I. Authority and Background

    GSFLs, IRLs, and GSILs are included in the list of ``covered 
products'' for which DOE is authorized to establish and amend energy 
conservation standards and test procedures. (42 U.S.C. 6292(a)(14)) 
DOE's test procedures for GSFLs, IRLs, and GSILs appear at title 10 of 
the Code of Federal Regulations (``CFR'') part 430, subpart B, appendix 
R (``appendix R''). The following sections discuss DOE's authority to 
establish and amend test procedures for GSFLs, IRLs, and GSILs, as well 
as relevant background information regarding DOE's amendments to the 
test procedures for these products.

A. Authority

    The Energy Policy and Conservation Act, as amended (``EPCA''),\1\ 
authorizes DOE to regulate the energy efficiency of a number of 
consumer products and certain industrial equipment. (42 U.S.C. 6291-
6317) Title III, Part B \2\ of EPCA established the Energy Conservation 
Program for Consumer Products Other Than Automobiles, which sets forth 
a variety of provisions designed to improve energy efficiency. These 
products include GSFLs, IRLs, and GSILs, the subject of this document. 
(42 U.S.C. 6292(a)(14))
---------------------------------------------------------------------------

    \1\ All references to EPCA in this document refer to the statute 
as amended through the Energy Act of 2020, Public Law 116-260 (Dec. 
27, 2020), which reflect the last statutory amendments that impact 
Parts A and A-1 of EPCA.
    \2\ For editorial reasons, upon codification in the U.S. Code, 
Part B was redesignated Part A.
---------------------------------------------------------------------------

    The energy conservation program under EPCA consists essentially of 
four parts: (1) testing, (2) labeling, (3) Federal energy conservation 
standards, and (4) certification and enforcement procedures. Relevant 
provisions of EPCA specifically include definitions (42 U.S.C. 6291), 
test procedures (42 U.S.C. 6293), labeling provisions (42 U.S.C. 6294), 
energy conservation standards (42 U.S.C. 6295), and the authority to 
require information and reports from manufacturers (42 U.S.C. 6296).
    The testing requirements consist of test procedures that 
manufacturers of covered products must use as the basis for (1) 
certifying to DOE that their products comply with the applicable energy 
conservation standards adopted under EPCA (42 U.S.C. 6295(s)), and (2) 
making other representations about the efficiency of those products (42 
U.S.C. 6293(c)). Similarly, DOE must use these test procedures to 
determine whether the products comply with any relevant standards 
promulgated under EPCA. (42 U.S.C. 6295(s))
    Federal energy efficiency requirements for covered products 
established under EPCA generally supersede State laws and regulations 
concerning energy conservation testing, labeling, and standards. (42 
U.S.C. 6297) DOE may, however, grant waivers of Federal preemption for 
particular State laws or regulations, in accordance with the procedures 
and other provisions of EPCA. (42 U.S.C. 6297(d))
    Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures 
DOE must follow when prescribing or amending test procedures for 
covered products. EPCA requires that any test procedures prescribed or 
amended under this section shall be reasonably designed to produce test 
results which measure energy efficiency, energy use or estimated annual 
operating cost of a covered product during a representative average use 
cycle (as determined by the Secretary) or period of use and shall not 
be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))
    EPCA, as codified, directs DOE to prescribe test procedures for 
fluorescent lamps and IRLs, taking into consideration the applicable 
standards of IES or ANSI. (42 U.S.C. 6293(b)(6)) Consideration of IES 
and ANSI standards aligns DOE test procedures with latest industry 
practices for testing electric lamps; therefore, DOE also considers 
these industry test standards when prescribing test procedures for 
GSILs.
    EPCA also requires that, at least once every 7 years, DOE evaluate 
test procedures for each type of covered product, including GSFLs, 
IRLs, and GSILs, to determine whether amended test procedures would 
more accurately or fully comply with the requirements for the test 
procedures to not be unduly burdensome to conduct and be reasonably 
designed to produce test results that reflect energy efficiency, energy 
use, and estimated operating costs during a representative average use 
cycle or period of use. (42 U.S.C. 6293(b)(1)(A))
    If the Secretary determines, on her own behalf or in response to a 
petition by any interested person, that a test procedure should be 
prescribed or amended, the Secretary shall promptly publish in the 
Federal Register proposed test procedures and afford interested persons 
an opportunity to present oral and written data, views, and arguments 
with respect to such procedures. The comment period on a proposed rule 
to amend a test procedure shall be at least 60 days and may not exceed 
270 days. In prescribing or amending a test procedure, the Secretary 
shall take into account such information as the Secretary determines 
relevant to such procedure, including technological developments 
relating to energy use or energy efficiency of the type (or class) of 
covered products involved. (42 U.S.C. 6293(b)(2)). If DOE determines 
that test procedure revisions are not appropriate, DOE must publish its 
determination not to amend the test procedures.
    In addition, EPCA requires that DOE amend its test procedures for 
all covered products to integrate measures of standby mode and off mode 
energy consumption into the overall energy efficiency, energy 
consumption, or other energy descriptor, unless the current test 
procedure already incorporates the

[[Page 53620]]

standby mode and off mode energy consumption, or if such integration is 
technically infeasible. (42 U.S.C. 6295(gg)(2)(A))
    If an integrated test procedure is technically infeasible, DOE must 
prescribe separate standby mode and off mode energy use test procedures 
for the covered product, if a separate test is technically feasible. 
(Id.) Any such amendment must consider the most current versions of the 
International Electrotechnical Commission (``IEC'') Standard 62301 \3\ 
and IEC Standard 62087 \4\ as applicable. (42 U.S.C. 6295(gg)(2)(A))

    \3\ IEC 62301, Household electrical appliances--Measurement of 
standby power (Edition 2.0, 2011-01).

Part 7: 2018).
---------------------------------------------------------------------------

    DOE is publishing this final rule in satisfaction of the 7-year 
review requirement specified in EPCA. (42 U.S.C. 6293(b)(1)(A))

B. Background

    DOE's existing test procedures for GSFLs, IRLs, and GSILs appear at 
appendix R (``Uniform Test Method for Measuring Average Lamp Efficacy 
(``LE''), Color Rendering Index (``CRI''), and Correlated Color 
Temperature (``CCT'') of Electric Lamps'').
    DOE most recently amended the test procedures for GSFLs and GSILs 
in a final rule published on January 27, 2012. 77 FR 4203. DOE updated 
several references to the industry test standards referenced in DOE's 
test procedures and established a lamp lifetime test method for GSILs. 
Id. In that final rule, DOE determined that amendments to the existing 
test procedure for IRLs were not necessary. Id.
    On August 8, 2017, DOE published in the Federal Register a request 
for information (``RFI'') seeking comments on the current test 
procedures for GSFLs, IRLs, and GSILs. 82 FR 37031 (``August 2017 
RFI''). On June 3, 2021, DOE published in the Federal Register a notice 
of proposed rulemaking (``NOPR'') proposing amendments to the current 
test procedures for GSFLs, IRLs, and GSILs. 86 FR 29888 (``June 2021 
NOPR'').
    DOE received comments in response to the June 2021 NOPR from the 
interested parties listed in Table I.1.

II. Synopsis of the Final Rule

    In this final rule, DOE amends 10 CFR part 429, 430.2, 430.3, 
430.23, 430.32, and appendix R as follows: (1) updates references to 
industry test standards to reflect current industry practices; (2) 
modifies, adds, and removes definitions to better align with the scope 
and test methods; (3) references specific sections within industry test 
standards for further clarity; (4) provides a test method for measuring 
CRI for incandescent lamps to support DOE requirements; (5) provides a 
test method for measuring lifetime of incandescent reflector lamps to 
support the Federal Trade Commission's (``FTC's'') labeling 
requirements; (6) clarifies test frequency and inclusion of cathode 
power in measurements for GSFLs; (7) decreases the sample size and 
specifies all metrics for all lamps be measured from the same sample of 
units. In addition, this final rule aligns terminology across appendix 
R, the relevant sections of 10 CFR part 429, 430.23(r), 430.32(n) and 
430.32(x) and updates language for conciseness and clarity.
    The adopted amendments are summarized in Table II.1 of this 
document compared to the test procedure provision prior to the 
amendment, as well as the reason for the adopted change.

    DOE has determined that the amendments described in section III of 
this document and adopted in this document will not alter the measured 
efficiency of GSFLs, IRLs, or GSILs, or require retesting or 
recertification solely as a result of DOE's adoption of the amendments 
to the test procedures. Additionally, DOE has determined that the 
amendments will not increase the cost of testing. Discussion of DOE's 
actions are addressed in detail in section III of this document.
    The effective date for the amended test procedures adopted in this 
final rule is 30 days after publication of this document in the Federal 
Register. Representations of energy use or energy efficiency must be 
based on testing in accordance with the amended test procedures 
beginning 180 days after the publication of this final rule.

III. Discussion

    In response to the June 2021 NOPR, DOE received several comments on 
the proposed amendments. The CA IOUs stated general support for 
updating the GSFL, IRL, and GSIL test procedures and encouraged the 
process to proceed expeditiously. (CA IOUs, No. 13 at pp. 2-3) Other 
comments addressed specific topics including updates to industry 
standards incorporated by reference, test methodologies, sampling and 
certification requirements, and test procedures costs and impacts. DOE 
discusses the comments received on the June 2021 NOPR in the following 
sections.

A. Scope of Applicability

    This final rule covers those consumer products that meet the 
definitions of ``general service fluorescent lamp,'' ``incandescent 
reflector lamp,'' and ``general service incandescent lamp'' as codified 
in DOE's regulations at 10 CFR 430.2.
    DOE defines a general service fluorescent lamp as a lamp that can 
be used to satisfy the majority of fluorescent lighting applications; 
and also specifies that it cannot be designed and marketed for eight 
non-general applications. 10 CFR 403.2.
    DOE defines an incandescent reflector lamp to mean any lamp in 
which light is produced by a filament heated to incandescence by an 
electric current and that: (1) has an inner reflective coating on the 
outer bulb to direct the light; (2) is not colored; (3) is not designed 
for rough or vibration service applications; (3) is not an R20 short 
lamp; (3) has an R, PAR, ER, BR, BPAR, or similar bulb shapes with an 
E26 medium screw base; (4) has a rated voltage or voltage range between 
115 and 130 volts; (5) has a diameter greater than 2.25 inches; and (6) 
has a rated wattage that is 40 watts or higher. 10 CFR 430.2.
    DOE defines a general service incandescent lamp as an incandescent 
or halogen lamp type intended for general service applications and 
that: (1) has a medium screw base; (2) has a lumen range of not less 
than 310 lumens and not more than 2,600 lumens or, in the case of a 
modified spectrum lamp, not less than 232 lumens and not more than 
1,950 lumens; and (3) has a voltage range between 110 and 130 volts. 
The definition also specifies 16 types of lamps to which the definition 
does not apply. 10 CFR 430.2.
    DOE received comments regarding rulemaking scope in response to the 
June 2021 NOPR.
    The CA IOUs commented that under DOE's definitional rulemaking 
published on January 19, 2017,\6\ GSILs, IRLs, compact fluorescent 
lamps (``CFLs''), as well as integrated light-emitting diode (``LED'') 
lamps and organic light-emitting diode (``OLED'') lamps are general 
service lamps (``GSLs''). The CA IOUs asserted that the statutory GSL 
efficacy requirement of 45 lumens per watt (``lm/W'') (i.e., the 
``backstop'') \7\ has been triggered. The

[[Page 53622]]

CA IOUs stated that applying the 45 lm/W standard across different 
lamps with common consumer utility would be a significant step towards 
a technology-neutral approach to regulating lighting efficiency. The CA 
IOUs further stated that GSILs and IRLs are both GSLs per DOE 
regulation and therefore are subject to the GSL test procedure 
published by DOE in September 2016.\8\ (CA IOUs, No. 13 at p. 2)
---------------------------------------------------------------------------

    \6\ On January 19, 2017, DOE published two final rules 
(``January 2017 Definition Final Rules'') revising the definitions 
of GSL and GSIL by bringing certain categories of lamps that had 
been excluded by statute from the definition of GSIL within the 
definitions of GSIL and GSL. 82 FR 7276; 82 FR 7322. On September 5, 
2019, DOE published a final rule withdrawing the definitions in the 
January 2017 Definition Final Rules and instead maintained the 
existing regulatory definitions of GSL and GSIL. 84 FR 46661. On 
August 19, 2021, DOE published a NOPR proposing to amend the 
existing regulatory definitions of GSL and GSIL to be those 
specified in the January 2017 Definition Final Rules. 86 FR 46611. 
On May 9, 2022, DOE published a final rule adopting definitions of 
GSL and GSIL and associated supplemental definitions as set forth in 
the January 2017 Definition Final Rules. 87 FR 27461 (``May 2022 
Definition Final Rule'').
    \7\ EPCA directs DOE to initiate a rulemaking process for GSLs 
prior to January 1, 2014, to determine whether: (1) to amend energy 
conservation standards for GSLs and (2) the exemptions for certain 
incandescent lamps should be maintained or discontinued. (42 U.S.C. 
6295(i)(6)(A)(i)) The rulemaking is not limited to incandescent lamp 
technologies and must include a consideration of a minimum standard 
of 45 lumens per watt for GSLs. (42 U.S.C. 6295(i)(6)(A)(ii)) EPCA 
provides that if the Secretary determines that the standards in 
effect for GSILs should be amended, a final rule must be published 
by January 1, 2017, with a compliance date at least 3 years after 
the date on which the final rule is published. (42 U.S.C. 
6295(i)(6)(A)(iii)) The Secretary must also consider phased-in 
effective dates after considering certain manufacturer and retailer 
impacts. (42 U.S.C. 6295(i)(6)(A)(iv)) If DOE fails to complete a 
rulemaking in accordance with 42 U.S.C. 6295(i)(6)(A)(i)-(iv), or if 
the final rule does not produce savings greater than or equal to the 
savings from a minimum efficacy standard of 45 lm/W, the statute 
provides a ``backstop'' under which DOE must prohibit sales of GSLs 
that do not meet a minimum 45 lm/W standard. (42 U.S.C. 
6295(i)(6)(A)(v)) On May 9, 2022, DOE published a final rule 
codifying the 45 lm/W backstop requirement. 87 FR 27439 (``May 2022 
Backstop Final Rule'').
    \8\ On October 20, 2016, DOE published a final rule adopting 
test procedures for GSLs that are not general service incandescent 
lamps, compact fluorescent lamps, or integrated light-emitting diode 
(``LED'') lamps. The test procedures were codified in 10 CFR part 
430, subpart B, appendix DD. 81 FR 72493.
---------------------------------------------------------------------------

    In the May 2022 Definition Final Rule and May 2022 Backstop Final 
Rule, DOE addressed the CA IOUs comments regarding the applicability of 
the 45 lm/W backstop requirement for GSLs. The May 2022 Backstop Final 
Rule codified the backstop requirement for GSLs, which includes IRLs 
and GSILs. Further, DOE provides test procedures for all GSLs in 
certain appendices to subpart B of 10 CFR part 430. DOE's test 
procedure codified in appendix DD, Uniform Test Method for Measuring 
the Energy Consumption and Energy Efficiency of General Service Lamps 
That Are Not General Service Incandescent Lamps, Compact Fluorescent 
Lamps, or Integrated LED Lamps, applies as the title indicates to all 
GSLs that are not GSILs, CFLs, or integrated LED lamps. The DOE test 
procedure for GSILs and IRLs is codified in appendix R; the DOE test 
procedure for CFLs is codified in appendix W, Uniform Test Method for 
Measuring the Energy Consumption of Compact Fluorescent Lamps; and the 
DOE test procedure for integrated LED lamps is codified in appendix BB, 
Uniform Test Method for Measuring the Input Power, Lumen Output, Lamp 
Efficacy, Correlated Color Temperature (CCT), Color Rendering Index 
(CRI), Power Factor, Time to Failure, and Standby Mode Power of 
Integrated Light-Emitting Diode (LED) Lamps. The scope of this 
rulemaking is limited to the review and revision of appendix R and the 
associated sampling and certification requirements.

B. Incorporation by Reference of Industry Test Standards

    The GSFL, IRL, and GSIL test procedures described in appendix R 
reference certain ANSI and IES standards. Industry periodically updates 
its testing standards to account for changes in technology, 
developments in test methodology, developments in test instruments, 
and/or changes in industry practice. Several of the referenced industry 
test standards have been updated by industry since DOE last amended its 
test procedures for GSFLs, IRLs and GSILs. In the June 2021 NOPR, DOE 
identified updated versions of the referenced industry standards 
incorporated by reference for appendix R as shown in Table III.1 of 
this document. DOE tentatively determined that the proposed updates to 
industry test standard references are clarifications and would not 
involve substantive changes to the test setup and methodology. 86 FR 
29888, 29892. DOE also initially determined that incorporation by 
reference of the latest versions of the industry standards would better 
align DOE test procedures with industry practice and further increase 
the clarity of the test methods. Id. DOE requested comment in the June 
2021 NOPR on its proposed adoption of the updated versions of the 
referenced industry test standards and its tentative determination that 
such adoption would not result in substantive changes to the DOE test 
procedure. Id.
    NEMA commented that it approved of adopting the latest versions of 
consensus standards proposed in the June 2021 NOPR. NEMA stated that 
none of the standards for which NEMA is Secretariat are slated for 
updates within the next six months and recommended that DOE proceed as 
proposed without concern as to whether new versions of the consensus 
standards are imminent. (NEMA, No. 12 at p. 2) IES stated that all IES 
standards have been elevated to ANSI status over the past two years and 
that it is an appropriate practice for DOE to adopt ANSI standards when 
they are available. IES also noted that previous versions of IES 
standards referenced by DOE are no longer supported or sold by IES. IES 
also requested that DOE reference its standards with the initialism 
``IES'' rather than ``IESNA'' and noted its new resource for 
illumination engineering terms, ANSI/IES LS-1-20, Lighting Science: 
Nomenclature and Definitions for Illuminating Engineering. (IES, No. 14 
at pp. 1-2)
    At the time of this final rule analysis, DOE did not identify more 
recent versions of industry standards than those proposed for adoption 
in the June 2021 NOPR. For the reasons discussed in the June 2021 NOPR 
and in the preceding paragraphs, DOE is adopting the latest versions of 
industry standards as proposed in the June 2021 NOPR. Further, for 
purposes of reference and accuracy, DOE specifies industry standards in 
the CFR according to the titles that appear in the industry test 
standard publication. DOE reviewed the titles of the relevant industry 
test standards to determine if they were accurately specified in the 
June 2021 NOPR. DOE determined that in the June 2021 NOPR it had 
erroneously specified the title of the 2020 version of standard LM-78 
with ``IESNA,'' whereas it is labeled as ``IES'' in the industry test 
standard publication. Accordingly, in this final rule, DOE has included 
the title of this industry standard using the initialism ``IES.'' DOE 
also reviewed ANSI/IES LS-1-20 and did not find terms in DOE's GSFL, 
IRL, and GSIL test procedures that required reference to ANSI/IES LS-1-
20.

---------------------------------------------------------------------------

    DOE has determined that, because these updates to industry standard 
references do not involve substantive changes to the test setup and 
methodology but rather clarifications that align DOE's test procedures 
with latest industry best practices, they would not affect measured 
values. Hence, in this final rule, DOE incorporates by reference for 
appendix R the industry standards ANSI C78.375A-2014 (R2020), ANSI 
C78.81-2016 (adopted for voluntary representations, as described 
further in this section), ANSI C78.901-2016 (adopted for voluntary 
representations, as described further in this section), ANSI C82.3-
2016, IES LM-9-20, IES LM-58-20, IES LM-45-20, IES LM-49-20, IES LM-20-
20, IES LM-54-20, IES LM-78-20, and CIE 15:2018.
    For certain lamps, in the latest versions of the industry standards 
ANSI C78.81-2016 and ANSI C78.901-2016, only high frequency reference 
ballast settings are specified, whereas previously low frequency 
settings were provided.\31\ Because cathode heat is not used at high 
frequency, the measured lamp efficacy would likely increase during high 
frequency operation compared to low frequency operation. DOE's test 
procedure requires testing at low frequency unless only high frequency 
settings are provided. Hence, the adoption of ANSI C78.81-2016 and ANSI 
C78.901-2016, which specify only high frequency ballast settings for 
certain lamps, would result in certain lamps that were previously 
tested at low frequency being tested at high frequency, negating the 
consideration of cathode heat.
---------------------------------------------------------------------------

    \31\ ANSI C78.81-2016 and/or ANSI C78.901-2016 remove low 
frequency reference ballast settings and provide only high frequency 
reference ballast settings for the following lamps: 32 Watt (``W''), 
48-Inch T8 lamp; 32 W U-shaped, 6-Inch Center T8 lamp; 31 W, U-
shaped, 1-5/8 Inch Center T8 lamp; 59 W, 96-Inch T8, Single Pin 
Instant Start lamp; and 25 W, 28 W, and 30 W 48-Inch T8 lamps. 
Additionally, two new lamp data sheets were added providing only 
high frequency reference ballast settings for the following lamps: 
30 W, U-shaped, 6-Inch Center T8 lamp and 54 W 96-Inch T8, Single 
Pin Instant Start lamp.
---------------------------------------------------------------------------

    In the June 2021 NOPR, DOE proposed to maintain the current 
references to ANSI C78.81-2010 and ANSI C78.901-2005 for determining 
compliance and to add provisions to allow manufacturers to make 
voluntary representations of applicable GSFLs at the high frequency 
settings specified in the 2016 versions of ANSI C78.81 and ANSI C78.901 
in accordance with test procedures specified in appendix R and 
associated sampling requirements. The voluntary representations would 
not be used for compliance but rather would be in addition to values 
obtained for compliance and used for determining if and how standards 
for GSFLs should be amended to accommodate testing at high frequency 
settings. 86 FR 29888, 29894.

[[Page 53624]]

    NEMA commented that it supports conducting GSFL tests using high 
frequency reference ballasts for purposes of making product performance 
claims. NEMA did not support use of high frequency ballast settings for 
the purposes of certification to DOE. NEMA commented that tests 
conducted using high frequency ballasts produce different results from 
those conducted on older technology. Further, NEMA commented that 
amending the DOE test procedure to use high frequency ballasts would 
add unnecessary burden without any benefit, because there is no new 
product development in GSFL technology, the technology is mature, and 
sales are declining. (NEMA, No. 12 at p. 2)
    As discussed in the June 2021 NOPR, DOE understands that the change 
in measured efficacy when testing on high frequency versus low 
frequency settings resulting from updated versions of ANSI C78.81 and 
ANSI C78.901 is not de minimis. 86 FR 29888, 29894. Adoption of test 
procedures that reference the latest versions of ANSI C78.81 and ANSI 
C78.901 would impact compliance under the current GSFL energy 
conservation standards and require reassessment of the energy 
conservation standards based on measured values tested according to DOE 
test procedures using the updated industry test standards (e.g., ANSI 
C78.81-2016 and ANSI C78.901-2016). Id. For these reasons and those 
discussed in the June 2021 NOPR, DOE is maintaining the ballast 
frequency specifications through references to ANSI C78.81-2010 and 
ANSI C78.901-2005 for determining compliance, as proposed. DOE is 
adding provisions to allow manufacturers to make voluntary 
representations of applicable GSFLs at the high frequency settings 
specified in the 2016 versions of ANSI C78.81 and ANSI C78.901 in 
accordance with test procedures specified in appendix R and associated 
sampling requirements. DOE will not use the voluntary representations 
to determine compliance with GSFL energy conservation standards. DOE 
may consider voluntary representations to evaluate whether standards 
for GSFLs should be amended to accommodate testing at high frequency 
settings.
    In this final rule, as proposed in the June 2021 NOPR, DOE is 
providing instructions in a new section 5.0 in appendix R for making 
voluntary representations for GSFLs that have high frequency reference 
ballast settings in ANSI C78.81-2016 and ANSI C78.901-2016.

C. Amendments to Appendix R

    In this final rule, DOE amends appendix R to improve the 
organization of the test procedures, further clarify test conditions 
and measurement steps, and cite specific sections of referenced 
industry test standards. Additionally, in this final rule, DOE removes 
references to rounding and sample size from appendix R, as these 
requirements are addressed in 10 CFR 429.27, and also removes 
references to minimum lifetime standards, as these are provided in 10 
CFR 430.32(x)(1)(iii)(A)-(B). DOE has determined that these updates to 
appendix R are not substantive, improve the clarity and consistency of 
the test method, provide explicit instructions for test methods likely 
already in use, and thereby, will not affect measured values. DOE 
details these amendments to appendix R in the following subsections.
1. Definitions
    In the June 2021 NOPR, DOE proposed to add and define the term 
``time to failure'' to support the procedure for determining lamp 
lifetime of lamps that use incandescent technology. 86 FR 29888, 29899. 
Section 4.2.3 of appendix R specifies a measurement procedure for 
testing the lifetime of GSILs. Furthermore, DOE's sampling plan for 
GSFLs at 10 CFR 429.27 specifies sampling requirements and procedures 
for determining a basic model's rated lifetime. 10 CFR 
429.27(a)(2)(iv). As discussed further in section III.D.3 of this 
document, in the June 2021 NOPR, DOE proposed to remove language in 10 
CFR 429.27(a)(2)(iv) stating that lifetime is the length of operating 
time between first use and failure of 50 percent of the sample size, 
and to instead directly describe what failure of 50 percent sample size 
means by specifying that the represented value of lifetime is equal to 
or less than the median time to failure of the sample. DOE proposed 
that this change would apply to both GSILs and IRLs (in newly proposed 
representation requirements for IRLs). To support these changes, DOE 
proposed in the June 2021 NOPR to add a definition in appendix R for 
``time to failure,'' as well as test methods, measurements, and 
calculations for determining time to failure, as discussed further in 
section III.C.4 of this document. In appendix R, DOE proposed to define 
``time to failure'' as the time elapsed between first use and the point 
at which the lamp ceases to produce measurable lumen output. Id.
    In the June 2021 NOPR, DOE also proposed certain changes related to 
the definition of ``lamp efficacy.'' Section 2.6 of appendix R defines 
``lamp efficacy'' as the ratio of measured lamp lumen output in lumens 
to the measured lamp electrical power input in watts, rounded to the 
nearest tenth, in units of lumens per watt. DOE also defines ``lamp 
efficacy'' at 10 CFR 430.2 as the measured lumen output of a lamp in 
lumens divided by the measured lamp electrical power input in watts 
expressed in units of lumens per watt. In the June 2021 NOPR, DOE 
proposed to replace the term ``lamp efficacy'' with ``initial lamp 
efficacy,'' and to simplify and clarify the definition by: (1) 
referencing lamp efficacy as defined in 10 CFR 430.2; (2) specifying 
that the value is determined after the lamp is stabilized and seasoned; 
and (3) removing references to rounding requirements, which DOE 
proposed to be addressed in 10 CFR 429.27 (see section III.D.5 for 
details on DOE's amendments to rounding requirements in 10 CFR 429.27). 
86 FR 29888, 29899.
    In the June 2021 NOPR, DOE also proposed certain changes related to 
the definition of ``lamp lumen output.'' Section 2.7 of appendix R 
defines ``lamp lumen output'' as the total luminous flux produced by 
the lamp, at the reference condition, in units of lumens. DOE proposed 
to replace the term ``lamp lumen output'' with ``initial lumen output'' 
and to simplify the definition to ``lumen output of the lamp,'' and add 
the clarification that the initial lumen output of the lamp is measured 
at the end of the lamp seasoning and stabilization. Id.
    In the June 2021 NOPR, DOE also proposed certain changes related to 
the definition of ``lamp electrical power input.'' Section 2.8 of 
appendix R defines ``lamp electrical power input'' as the total 
electrical power input to the lamp, including both arc and cathode 
power where appropriate, at the reference condition, in units of watts. 
DOE proposed to replace the term ``lamp electrical power input'' with 
``initial input power,'' and to simplify the definition to ``the input 
power to the lamp,'' and add the clarification that initial input power 
of the lamp is measured at the end of the lamp seasoning and 
stabilization. Id. DOE explained in the June 2021 NOPR that these 
proposed changes would more accurately describe the values being 
determined and measured by the test methods in appendix R. Id.
    Section 2.9 of appendix R defines ``reference condition'' as the 
test condition specified in IES LM-9 for general service fluorescent 
lamps, in IESNA LM-20 for incandescent reflector lamps, and in IES LM-
45 for general

[[Page 53625]]

service incandescent lamps. In the June 2021 NOPR, DOE proposed to 
remove the term ``reference condition'' because it is neither 
referenced in nor necessary for the test procedure. 86 FR 29888, 29899.
    Section 2.2 of appendix R defines ``ANSI Standard'' as a standard 
developed by a committee accredited by the American National Standards 
Institute. Section 2.3 of appendix R defines ``CIE'' as the 
International Commission on Illumination. Section 2.5 of appendix R 
defines ``IESNA'' as the Illuminating Engineering Society of North 
America. In the June 2021 NOPR, DOE proposed to remove these 
definitions for ``ANSI Standard,'' ``CIE,'' and ``IESNA'' in appendix R 
because 10 CFR 430.3 contains the relevant terms--specifically, 
``ANSI'', ``CIE'', and ``IESNA'' and the associated full names of these 
industry standards organizations.
    Section 2.4 of appendix R defines ``CRI'' as Color Rendering Index 
as defined in 10 CFR 430.2. In the June 2021 NOPR, DOE proposed to 
remove the definition for ``CRI,'' which only references the 
definitions in 10 CFR 430.2. Further, in the June 2021 NOPR, DOE 
incorrectly proposed to remove the definition of ``CCT'' in appendix R. 
However, the definition of ``CCT'' does not appear in appendix R. 86 FR 
29888, 29899.
    Section 2.1 of appendix R specifies that to the extent that 
definitions in the referenced IESNA and CIE standards do not conflict 
with the DOE definitions, the definitions specified in Section 3.0 of 
IES LM-9, Section 3.0 of IESNA LM-20, section 3.0 and the Glossary of 
IES LM-45, Section 2 of IESNA LM-58, and Appendix 1 of CIE 13.3 shall 
be included. In the June 2021 NOPR, DOE proposed to update the section 
reference from Section 2 of IES LM-58 to the corresponding Section 3 of 
IES LM-58-20 (which DOE proposed to incorporate by reference) and to 
delete the reference to the Glossary of IES LM-45, as it no longer 
exists in the updated 2020 version (which DOE proposed to incorporate 
by reference). 86 FR 29888, 29899.
    NEMA agreed with DOE's proposals to modify these definitions. 
(NEMA, No. 12 at p. 3) No other comments were received on the proposed 
amendments regarding definitions.
    For the reasons discussed in the preceding paragraphs and in the 
June 2021 NOPR, in this final rule DOE is adopting these revisions to 
definitions as proposed in the June 2021 NOPR.
2. General Instructions
    In the June 2021 NOPR, DOE proposed to add a ``General 
Instructions'' section to appendix R to improve the readability of and 
streamline the test methods in appendix R. This section would specify 
test practices applicable to all lamps covered by appendix R. 
Specifically, to ensure consistency in measurements, DOE proposed to 
include in the ``General Instructions'' section the following 
specifications: (1) where there is a conflict, the language of the test 
procedure in this appendix takes precedence over any materials 
incorporated by reference; (2) maintain lamp operating orientation 
throughout seasoning and testing, including storage and handling 
between tests; (3) if a lamp breaks, becomes defective, fails to 
stabilize, exhibits abnormal behavior (such as swirling),\32\ or stops 
producing light prior to the end of the seasoning period, replace the 
lamp with a new unit; however, if a lamp exhibits one of the conditions 
listed in the previous sentence only after the seasoning period ends, 
include the lamp's measurements in the sample; and (4) operate GSILs 
and IRLs at the rated voltage for incandescent lamps as defined in 10 
CFR 430.2. 86 FR 29888, 29899. DOE tentatively concluded that these 
proposals only explicitly state best practices already being followed 
by labs for testing lamps, and would not change current requirements of 
the DOE test procedure. 86 FR 29888, 29899-29900.
---------------------------------------------------------------------------

    \32\ This term refers to the visual observation that a beam or 
line of light appears to be ``swirling'' or ``spiraling'' within a 
fluorescent tube lamp.
---------------------------------------------------------------------------

    In particular, the proposed specification to operate GSILs and IRLs 
at the rated voltage for incandescent lamps as defined in 10 CFR 430.2 
would maintain consistency with the current specifications for 
determining the test voltage of incandescent lamps as specified in the 
definition of ``rated voltage with respect to incandescent lamps'' in 
10 CFR 430.2. DOE proposed to move this voltage specification currently 
codified as part of the definition in 10 CFR 430.2 to the ``General 
Instructions'' section of appendix R to make explicit that the 
specification applies to GSIL and IRL test methods in appendix R. 86 FR 
29888, 29900.
    DOE did not receive any comments on the proposed specifications 
regarding lamp breakage. For the reasons discussed in the preceding 
paragraphs and in the June 2021 NOPR, in this final rule DOE adopts the 
proposed general instructions regarding lamp breakage.
    DOE received several comments on the remaining proposed general 
instructions specifications. NEMA supported adding general instructions 
in appendix R but recommended certain revisions to the proposed text. 
In the case of conflicting requirements, NEMA suggested that industry 
and DOE work mutually to resolve conflicts between referenced industry 
standards and appendix R rather than allow appendix R to take 
precedence. (NEMA, No. 12 at pp. 3-4)
    By requiring that appendix R shall take precedence when there are 
conflicts between it and referenced industry standards, DOE ensures 
that all testing is conducted using a consistent methodology and not a 
case-by-case approach. Further, most instructions in appendix R 
currently reference industry standards, with the exception of DOE's 
instructions for addressing lamps without industry standard data sheets 
and recording measured values.
    For the reasons discussed in the preceding paragraphs and in the 
June 2021 NOPR, in this final rule DOE adopts the proposed provision in 
the June 2021 NOPR that appendix R shall take precedence over industry 
standards in the event of conflicting requirements.
    In regard to lamp orientation, NEMA recommended that lamp 
orientation be maintained during storage and handling only if it is 
practical, rather than always be maintained as proposed by DOE. NEMA 
referenced IES LM-54, which states that maintaining orientation through 
storage and handling is recommended but not required. In addition, NEMA 
stated that instruction should be added that for 4-foot T5 miniature 
bipin standard and high output lamps, the procedure in Section 6.2.2 of 
IES LM-9-20 should be followed. This section specifies that these lamp 
types must be seasoned in the vertical orientation but measured 
horizontally. (NEMA, No. 12 at pp. 3-4)
    DOE notes that Section 6.1.1 of IES LM-54-20 states that for 
fluorescent lamps, maintaining the orientation during seasoning when 
handling, transporting, or storing the lamps can reduce lamp 
stabilization time, and that this practice is generally not required 
but is effective and recommended. DOE notes that Section 6.1 of IES LM-
9-20 specifies for 4-foot T5 miniature bipin standard and high output 
lamps an exception to the rule of maintaining lamp orientation during 
seasoning and testing and references Section 6.2.2 of IES LM-9-20, 
which specifies that they be seasoned in the vertical position and 
measured in the horizontal position. DOE also notes that Section 6.2.4 
of IES

[[Page 53626]]

LM-9-20 states that when transferring lamps, the pin connections and 
orientation used during warm-up should be maintained.
    To incorporate the recommended and required specifications in 
industry standards, in this final rule, DOE is specifying in the 
General Instructions that (1) lamp operating orientation should be 
maintained throughout seasoning and testing, except for T5 miniature 
bipin standard and high output GSFLs, which should follow Section 6.2.2 
of IES LM-9-20; (2) for all GSFLs, lamp orientation must be maintained 
when transferring lamps from a warm-up position to the photometric 
equipment per Section 6.2.4 of IES LM-9-20; and (3) lamp orientation 
must be maintained at all other times, if practical.
    Regarding the proposed instructions for rated voltage, the CA IOUs 
commented that the current DOE test procedures requiring that GSILs and 
IRLs be tested at the marked voltage could result in exemption of 
certain lamps from standards and thereby, reduced energy savings. The 
CA IOUs stated that the current definitions for GSILs encompass lamps 
that operate between 110 and 130 V with a minimum light output of 310 
lumens; therefore, a GSIL rated at 100 V may produce less than 310 
lumens when tested and thus not be subject to regulation, even though 
it could produce greater than 310 lumens when operated at the more 
common 120 V. The CA IOUs cited concerns expressed by the Appliance 
Standards Awareness Project (``ASAP'') that manufacturers may re-rate 
medium-screw base incandescent lamps at voltages lower than they are 
operated in common use, yielding results not representative of actual 
performance for the majority of consumers. Hence, the CA IOUs 
recommended that DOE test procedures for GSILs and IRLs should require 
all medium base lamps to be tested at either 120 or 240 V. (CA IOUs, 
No. 13 at pp. 2-3)
    As noted in the June 2021 NOPR, DOE did not propose to change the 
test voltage requirements for GSILs and IRLs. 86 FR 29888, 29900. For 
IRLs, modifying the test voltage requirements would change the rated 
voltage for certain IRLs and potentially exclude them from the 
definition of IRL, which is defined as having a rated voltage or 
voltage range that lies at least partially in the range of 115 and 130 
V. 10 CFR 430.2. Further, because energy conservation standards are in 
part determined by the rated voltage of the IRL, changes to rated 
voltage may subject lamps to different standards. Regarding GSILs, 
DOE's review of the market has shown that even with the current test 
voltage requirements, GSILs are predominantly rated at 120 V. Hence, 
DOE does not find that manufacturers are re-rating voltages of GSILs to 
be excluded from regulation. Therefore, in this final rule, DOE is 
maintaining the current specifications for determining the test voltage 
of incandescent lamps as specified in the definition of ``rated voltage 
with respect to incandescent lamps'' in 10 CFR 430.2.
3. Test Method for Determining Initial Lamp Efficacy, CRI, and CCT
    In this final rule, as proposed in the June 2021 NOPR, DOE is 
establishing a section called ``Test Method for Determining Initial 
Input Power, Initial Lumen Output, Initial Lamp Efficacy, CRI, and 
CCT'' and including existing sections regarding these measurements as 
subsections. DOE also proposed changes to test conditions, setup, 
methods, measurements and calculations that are detailed in the 
sections below. 86 FR 29888, 29900.
a. Test Conditions and Setup
    In the June 2021 NOPR, for clarity, DOE proposed to include the 
term ``setup'' in the title of ``Test Conditions'' (i.e., ``Test 
Conditions and Setup'') and modify the existing language to use the 
phrase ``establish ambient, physical, and electrical conditions'' 
consistently. Additionally, for GSFLs, DOE proposed to move the 
specifications regarding appropriate voltage and current conditions and 
reference ballast settings from the ``Test Methods and Measurements'' 
section to ``Test Conditions and Setup,'' as these requirements are 
part of the electrical conditions and setup that must be met prior to 
taking any measurements. 86 FR 29888, 29900. DOE received no comments 
regarding these modifications. For the reasons discussed in the June 
2021 NOPR, DOE is adopting these proposed changes in this final rule.
    Further, in the June 2021 NOPR, DOE proposed to specify that when 
operating at low frequency, cathode power must be included in the 
measurement if ANSI C78.81 or ANSI C78.901 classifies the circuit 
application as ``rapid start'' for that GSFL lamp type. 86 FR 29888, 
29901. If these industry test standards classify the circuit 
application as something other than ``rapid start,'' DOE proposed that 
cathode power should not be included. Id. DOE also proposed to specify 
that cathode power must not be included in measurements when operating 
at high frequency. Id.
    Additionally, for GSFL lamp types that do not have lamp data sheets 
listed in industry test standards, section 4.1.2 of appendix R provides 
reference ballast settings with which to test. In the June 2021 NOPR, 
DOE proposed to add to the specified reference ballast settings 
instructions on whether the lamp must be tested at low or high 
frequency or include cathode power (see Table III.2 of this document). 
86 FR 29888, 29900-29901. DOE's proposal was intended to base the newly 
established instructions on how the lamp types most similar to the lamp 
type not contained in the industry test standard are tested. 86 FR 
29888, 29901.

    As indicated by Table III.2 of this document, DOE's proposed 
instructions provided cathode power and frequency operation 
instructions by lamp length, base, and diameter for GSFL types lacking 
ANSI data sheets.
---------------------------------------------------------------------------

    \33\ 86 FR 29888, 29901.
---------------------------------------------------------------------------

    NEMA, in its comments, suggested revisions to the proposed 
instructions in Table III.2 of this document. NEMA suggested adding 
lamp wattage as a determining factor. Specifically, NEMA requested the 
following changes: (1) 4-foot medium bipin (``MBP'') T8 lamps greater 
than or equal to 25 W, but less than 32 W, tested at low frequency 
should be tested without cathode power rather than with cathode power 
as proposed; (2) 2-foot U-shaped T8 lamps greater than or equal to 25 
W, but less than 31 W, tested at low frequency should be tested without 
cathode power rather than with cathode power as proposed. NEMA also 
recommended that DOE's instructions in Table III.2 of this document 
apply to wattages greater than or equal to 49 W for the 8-foot slimline 
single pin (``SP'') T8 and T12 lamps. NEMA stated that its changes were 
based on the most similar lamp type in the industry test standard. 
(NEMA, No. 12 at pp. 2-3)
    As noted, in proposing the test frequency and cathode power 
specifications for a lamp that does not have a lamp data sheet in 
industry standards, DOE used the lamp data sheet of a lamp type most 
similar to the lamp without a lamp data sheet. NEMA commented that it 
used the same approach in recommending revisions to DOE's proposals. 
Based on this comment, DOE assumes that NEMA's recommendation that 4-
foot MBP T8 and 2-foot U-shaped T8 lamps, respectively less than 32 W 
and 31 W, be tested without cathode power is based on lamp datasheets 
for reduced wattage (i.e., 25 W, 28 W, 30 W) 4-foot MBP lamp types in 
ANSI C78.81-2010. Reduced wattage 4-foot MBP lamp types have lamp 
datasheets that specify an instant start/program start circuit and 
provide specifications for testing at low frequency either with or 
without cathode power. NEMA indicates that manufacturers are choosing 
to test these lamps without cathode power. (NEMA, No. 12 at pp. 2-3) To 
use the proxy lamp data sheet that most accurately reflects the lamp 
without a data sheet and to reflect how manufacturers are using the 
specifications in the lamp data sheet, in this final rule, DOE adopts 
NEMA's suggested revisions to test these 4-foot MBP T8 and 2-foot U-
shaped T8 lamps without cathode power. Additionally, because the 
circuit design may not be apparent (i.e., rapid/instant/program start 
marked on the lamp) for a lamp without a lamp data sheet, DOE agrees to 
use wattage to identify the lamps that should not be tested with 
cathode power for these 4-foot MBP T8 and 2-foot U-shaped T8 lamps. DOE 
has amended the table provided in the June 2021 NOPR to reflect this 
change (see Table III.3 of this document).
    In its comments, NEMA also recommended that DOE's instruction 
regarding test frequency and cathode power should be limited to lamps 
with certain wattages (i.e., 4-foot MBP lamps and 2-foot U-shaped lamps 
greater than or equal to 25 W and 8-foot SP slimline lamps greater than 
or equal to 49 W). (NEMA, No. 12 at pp. 2-3) This suggested change 
would capture some but not all of the lamps covered under the 
definition of ``fluorescent lamp.'' \34\ DOE's proposed instructions 
for addressing lamp types that are not included in ANSI C78.81 or ANSI 
C78.901 lamp data sheets are to address all lamp types and wattages, 
including lamps that may be introduced by a manufacturer in the future 
and/or may become the subject of standards. Hence, DOE is not including 
NEMA's suggested wattage limitations in this final rule.
---------------------------------------------------------------------------

    \34\ ``Fluorescent lamp'' is defined as a low pressure mercury 
electric-discharge source in which a fluorescing coating transforms 
some of the ultraviolet energy generated by the mercury discharge 
into light, including only the following: (1) Any straight-shaped 
lamp (commonly referred to as 4-foot medium bipin lamps) with medium 
bipin bases of nominal overall length of 48 inches and rated wattage 
of 25 or more; (2) Any U-shaped lamp (commonly referred to as 2-foot 
U-shaped lamps) with medium bipin bases of nominal overall length 
between 22 and 25 inches and rated wattage of 25 or more; (3) Any 
rapid start lamp (commonly referred to as 8-foot high output lamps) 
with recessed double contact bases of nominal overall length of 96 
inches; (4) Any instant start lamp (commonly referred to as 8-foot 
slimline lamps) with single pin bases of nominal overall length of 
96 inches and rated wattage of 49 or more; (5) Any straight-shaped 
lamp (commonly referred to as 4-foot miniature bipin standard output 
lamps) with miniature bipin bases of nominal overall length between 
45 and 48 inches and rated wattage of 25 or more; and (6) Any 
straight-shaped lamp (commonly referred to 4-foot miniature bipin 
high output lamps) with miniature bipin bases of nominal overall 
length between 45 and 48 inches and rated wattage of 44 or more. 10 
CFR 430.2.
---------------------------------------------------------------------------

    Finally, NEMA commented that the label in Table III.2 of this 
document for the 4-foot T5 standard and high output lamp type should be 
``miniature bipin (``MiniBP'')'' rather than ``MBP.'' (NEMA, No. 12 at 
pp. 2-3) DOE agrees that the base type for the 4-foot T5 standard and 
high output lamps was mislabeled in Table III.2 of the June 2021 NOPR 
and should be MiniBP rather than MBP (see Table III.3 for correction).
    Table III.3 summarizes the revised frequency and cathode power test 
specifications for GSFLs adopted in this final rule.

------------------------------------------------------------------------

    Appendix R currently references IES LM-9, IES LM-45, and IES LM-20 
in their entirety for test conditions. In the June 2021 NOPR, DOE 
proposed to specify the relevant sections of the industry test 
standards; specifically, that ambient, physical, and electrical 
conditions be established as described in Sections 4.0, 5.0, 6.1, 6.5 
and 6.6 of

[[Page 53628]]

IES LM-9 for GSFLs; Sections 4.0, 5.0, 6.1, 6.3 and 6.4 of IES LM-45 
for GSILs; and Sections 4.0 and 5.0 of IES LM-20 for IRLs. 86 FR 29888, 
29901.
    In its comments, NEMA agreed with the proposed references to the 
specified sections of IES LM-9, IES LM-45, and IES LM-20 for 
establishing ambient, physical, and electrical conditions, as well as 
seasoning and stabilization. (NEMA, No. 12 at p. 4) For the reasons 
discussed in the June 2021 NOPR and in the preceding paragraphs, in 
this final rule DOE adopts the proposed amendments to test conditions 
and setup in appendix R.
b. Test Methods, Measurements, and Calculations
    Section 3.1 of appendix R specifies that for GSFLs, the ambient 
conditions of the test and the electrical circuits, reference ballasts, 
stabilization requirements, instruments, detectors, and photometric 
test procedure and test report shall be as described in the relevant 
sections of IES LM-9. Section 3.2 of appendix R specifies that for 
GSILs, the selection and seasoning (initial burn-in) of the test lamps, 
the equipment and instrumentation, and the test conditions shall be as 
described in IES LM-45. Section 3.3 of appendix R specifies that for 
IRLs, the selection and seasoning (initial burn-in) of the test lamps, 
the equipment and instrumentation, and the test conditions shall 
conform to Sections 4.2 and 5.0 of IESNA LM-20.
    In the June 2021 NOPR, DOE proposed to replace these references of 
industry test standards in general to list specific sections of the 
industry standard. 86 FR 29888, 29901. The proposed section references 
as well as proposed changes to seasoning, stabilization, initial power 
and initial lumen output measurements, and certain calculations are 
detailed in the sections which follow.
Seasoning and Stabilization
    In the June 2021 NOPR, DOE proposed to state explicitly that lamps 
must be seasoned and stabilized according to Section 6.2 of IES LM-45 
for GSILs and Section 6.0 of IES LM-20 for IRLs. 86 FR 29888, 29901. 
For GSFLs, DOE proposed to state that lamps must be seasoned and 
stabilized in accordance with Sections 6.1, 6.2, 6.3, and 6.4 of IES 
LM-9. 86 FR 29888, 29902. DOE tentatively determined that the proposed 
updates would only specify more exact industry reference to current 
specifications and would not change current requirements of the DOE 
test procedure. 86 FR 29888, 29901, 29902. DOE received no comments on 
the proposed changes. For the reasons discussed in the June 2021 NOPR 
and in the preceding paragraphs, DOE is adopting the proposed 
amendments regarding references for seasoning and stabilization.
Photometric Measurements
    DOE proposed to specify that initial lumen output measurements be 
taken in accordance with Section 7.0 in IES LM-9 for GSFLs, Section 7.0 
in IES LM-45 for GSILs, and Section 7.0 or 8.0 in IES LM-20 for IRLs. 
86 FR 29888, 29902. DOE tentatively determined that these section 
references would not limit manufacturers from using one specific method 
for taking photometric measurements (i.e., goniophotometer, integrating 
sphere). Id. Additionally, for IRLs, DOE proposed to require measuring 
initial lumen output rather than total forward lumens. Id. DOE 
tentatively found that, because a reflector lamp is designed to focus 
lumens in a specific direction rather than in all directions, the term 
``total forward lumens'' has the same meaning as ``initial lumen 
output.'' Id.
    Regarding photometric measurements and DOE's proposal to continue 
to allow multiple methods for taking photometric measurements, the CA 
IOUs reiterated its comment submitted in response to the August 2017 
RFI in which the CA IOUs expressed support for the exclusive use of the 
integrating sphere method for measuring the light output of GSFLs, 
IRLs, and GSILs. The CA IOUs stated that they understand that while 
there are aspects of lamp performance (such as color rendering), 
reliability, and standby energy consumption that are technology-
specific, not requiring exclusive use of the integrating sphere method 
was a missed opportunity to set a technology-neutral test method. In 
addition, the CA IOUs expressed support for DOE's proposal to measure 
initial lumens rather than total forward lumens for IRLs. (CA IOUs, No. 
13 at p. 2)
    For this final rule, DOE reviewed whether to require exclusive use 
of the integrating sphere method and came to the same conclusion as in 
the June 2021 NOPR that both the goniophotometer and integrating sphere 
method should be allowed for measurement, as this may provide 
logistical flexibility for manufacturers. Additionally, the integrating 
sphere and goniophotometer methods can be used across lamp 
technologies. Therefore, DOE continues to allow the use of both the 
goniophotometer and integrating sphere methods. In this final rule, for 
the reasons discussed in the June 2021 NOPR and in the preceding 
paragraphs, DOE is adopting the industry standard section references 
for photometric measurements and changing the term ``total forward 
lumens'' to ``initial lumen output'' for IRLs in appendix R as proposed 
in the June 2021 NOPR.
Determining CRI and CCT
    Manufacturers of GSILs are required to certify CRI values (see 10 
CFR 429.27(b)(2)(iii)), and DOE's standards for GSILs include a minimum 
CRI requirement (see 10 CFR 430.32(x)(1)(iii)(A) and (B)). In addition, 
the Energy Independence and Security Act of 2007 (``EISA;'' Pub. L. 
110-140) established a CRI requirement for IRLs.\35\ Section 4.4 of 
appendix R provides specifications for determining CRI for GSFLs, but 
does not address determining CRI for either GSILs or IRLs.
---------------------------------------------------------------------------

    \35\ Section 321(a) of the Energy Independence and Security Act 
of 2007 (``EISA 2007'') established CRI requirements for lamps that 
are intended for a general service or general illumination 
application (whether incandescent or not); have a medium screw base 
or any other screw base not defined in ANSI C81.61-2006; are capable 
of being operated at a voltage at least partially within the range 
of 110 to 130 volts; and are manufactured or imported after December 
31, 2011.
---------------------------------------------------------------------------

    In the June 2021 NOPR, DOE proposed to include a test method for 
determining CRI of GSILs and IRLs in appendix R. 86 FR 29888, 29902. 
Specifically, DOE proposed to require that CRI of GSILs be determined 
in accordance with Section 7.4 of IES LM-45 and CIE 13.3 and that CRI 
of IRLs be determined in accordance with CIE 13.3. Id. Additionally, 
regarding GSFLs, for completeness, DOE proposed to state that, in 
addition to CIE 13.3, the CRI of GSFLs be determined in accordance with 
Section 7.6 of IES LM-9. Id. Because CIE 13.3 is the industry test 
standard for testing CRI of all lamps, DOE tentatively found that CRI 
is likely already being measured in accordance with this standard, and 
therefore, tentatively concluded that the proposed test method for CRI 
would establish procedures already being followed. Id.
    Currently, appendix R requires CCT for GSFLs to be determined in 
accordance with IES LM-9, and CCT for incandescent lamps to be 
determined in accordance with CIE 15. In the June 2021 NOPR, DOE 
proposed to require that CCT of GSFLs be determined in accordance with 
Section 7.6 of IES LM-9 and CIE 15; CCT of GSILs be determined in 
accordance with Section 7.4 of IES LM-45 and CIE 15; and CCT of IRLs be 
determined in accordance with CIE 15. 86 FR 29888, 29902.
    In its comments, NEMA agreed with the proposed industry test 
standard references for measuring CCT and CRI.

[[Page 53629]]

(NEMA, No. 12 at p. 4) For the reasons discussed in the June 2021 NOPR 
and in the preceding paragraphs, DOE adopts the industry standard 
section references for the measurement of CRI and CCT as proposed in 
the June 2021 NOPR.
4. Test Methods, Measurements, and Calculations for Determining Time to 
Failure
    In the June 2021 NOPR, to improve the organization of appendix R, 
DOE proposed to create a section called ``Test Method for Determining 
Time to Failure for General Service Incandescent Lamps and Incandescent 
Reflector Lamps'' and subsections, ``Test Conditions and Setup,'' and 
``Test Methods, Measurements, and Calculations.'' 86 FR 29888, 29903. 
To clarify the existing test method for determining the time to failure 
of GSILs and adopt the same test method for determining time to failure 
of IRLs, DOE proposed to include information on test conditions, 
seasoning and stabilization, and to remove information not pertinent to 
determining the time to failure value of the lamp. Id. Specifically, 
DOE proposed to measure lifetime of IRLs in accordance with IES LM-49 
and use the same methods as for GSIL lifetime testing. Id. To specify 
the ambient, physical, and electrical conditions for lifetime testing 
of GSILs and IRLs, DOE proposed to reference Sections 4.0 and 5.0 of 
IES LM-49. DOE also proposed to specify that the lamps must be seasoned 
and stabilized and to reference Section 6.2 of IES LM-45 for these 
procedures. Id. Further, DOE proposed to require measuring ``time to 
failure'' in accordance with Section 6.0 of IES LM-49 (see section 
III.C.1 for definition). Id. Additionally, DOE proposed to update the 
existing reference from Section 6.1 of IES LM-49-01 to corresponding 
Section 6.4 of IES LM-49-20 in the provision disallowing accelerated 
testing. Id. Finally, because it relates to the standard rather than 
the test procedure, DOE proposed to remove language in section 4.2.3 of 
appendix R stating that the lamp will be deemed to meet minimum rated 
lifetime standards if greater than 50 percent of the sample size meets 
the minimum rated lifetime. Id.
    DOE tentatively determined that these proposed updates would not 
change current requirements for testing lifetime of GSILs, as the 
updates only explicitly state certain steps of the referenced industry 
standard for determining time to failure for incandescent lamps and 
provide the associated section references to an industry test standard 
already incorporated by reference. Id. DOE also tentatively determined 
that because the proposed requirements for testing lifetime of IRLs 
reference IES LM-49, the industry standard for testing lifetime of 
incandescent lamps, they are not substantively different from those 
manufacturers are currently using to conduct this test. Id.
    In its comments, NEMA agreed with DOE's proposed section references 
in IES LM-49 for establishing ambient, physical, and electrical 
conditions and measuring time to failure, as well as proposed section 
references in IES LM-45 for seasoning and stabilization. (NEMA, No. 12 
at p. 4) DOE received no other comments on its proposals regarding test 
methods, measurements, and calculations for determining time to 
failure. For the reasons discussed in the June 2021 NOPR and in the 
preceding paragraphs, DOE adopts the updates to the organization of 
test procedure provisions and to the method of determining time to 
failure as proposed in the June 2021 NOPR.

D. Amendments to 10 CFR 429.27, 10 CFR 429.33 and 10 CFR 430.2

    Sampling, certification, and rounding requirements for GSFLs, IRLs, 
and GSILs are currently specified in 10 CFR 429.27. In this final rule, 
as proposed in the June 2021 NOPR (see 86 FR 29888, 29903), DOE is 
reorganizing 10 CFR 429.27 to apply only to GSFLs (as opposed to GSFLs, 
GSILs, and IRLs), establishing new Sec.  429.55 \36\ for IRLs, and 
establishing new Sec.  429.66 for GSILs, so that each lamp type (i.e., 
GSFL, IRL, GSIL) has its own section within 10 CFR part 429. 
Accordingly, as proposed (see 86 FR 29888, 29903), DOE is also revising 
10 CFR 429.33 to replace references to 10 CFR 429.27 with references to 
the specific, separate sections for each lamp type. DOE has determined 
that the updates to 10 CFR 429.27, 10 CFR 429.33 and 10 CFR 430.2 are 
not substantive changes, improve the clarity of the sampling, 
certification, and rounding requirements for GSFLs, IRLs, and GSILs, 
and thereby will not affect measured values. DOE details these 
amendments in the following subsections.
---------------------------------------------------------------------------

    \36\ In the June 2021 NOPR, DOE had proposed establishing 10 CFR 
429.38 for IRLs. Subsequent to publishing the June 2021 NOPR, DOE 
has reserved 10 CFR 429.38 for non-class A external power supplies.
---------------------------------------------------------------------------

1. Definitions
Basic Model
    In the June 2021 NOPR, DOE proposed, for clarity, to update the 
definition of ``basic model'' in 10 CFR 430.2 to replace ``lumens per 
watt (lm/W)'' with ``lamp efficacy.'' 86 FR 29888, 29903. DOE 
tentatively determined that this change would improve clarity by using 
the name of the metric instead of the unit of measure. DOE received no 
comments on the proposed change. Id. In this final rule DOE is adopting 
the proposed modification to the definition of ``basic model.''
Definitions and References to ``Rated''
    In the June 2021 NOPR, DOE proposed to replace references to 
``rated lumen output'' and ``rated lifetime'' in 10 CFR 429.27 with, 
respectively, ``initial lumen output'' and ``lifetime.'' 86 FR 29888, 
29904. DOE stated that the term ``rated'' can lead to misunderstanding 
to the extent a reader interprets it as a standardized value rather 
than one that is determined through measurements. Id.
    In its comments, NEMA agreed with the proposed replacements of 
``rated lumen output'' and ``rated lifetime.'' (NEMA, No. 12 at p. 5) 
For the reasons discussed in the June 2021 NOPR and in the preceding 
paragraphs, DOE is replacing the references of ``rated lumen output'' 
and ``rated lifetime'' in 10 CFR 429.27 with, respectively, ``initial 
lumen output'' and ``lifetime'' as proposed in the June 2021 NOPR.
    ``Rated wattage'' for GSILs, IRLs, and GSFLs (without a lamp 
datasheet) is defined in 10 CFR 430.2 as the electrical power measured 
according to appendix R. In the June 2021 NOPR, DOE proposed to clarify 
this definition by replacing the references to appendix R with 
references to the relevant sections in 10 CFR part 429 and replacing 
``electrical power'' with ``initial input power.'' 86 FR 29888, 29904. 
The resulting modification provided clearer directions for determining 
rated wattage by specifying that the rated wattage is the represented 
value of electrical power as determined in the appropriate 10 CFR part 
429 section derived from the initial input power measured in appendix 
R.
    In 10 CFR 430.2, the term ``rated lifetime for general service 
incandescent lamps'' means the length of operating time of a sample of 
lamps (as defined in 10 CFR 429.27(a)(2)(iv)) between first use and 
failure of 50 percent of the sample size in accordance with test 
procedures described in IESNA LM-49, as determined in section 4.2 of 
appendix R. The operating time is based on the middle lamp operating 
time for an odd number of samples and the average operating time of the 
two middle lamps for an even number of samples. See 10 CFR 430.2. 
Instructions for determining the length of operating time using middle 
samples are specified

[[Page 53630]]

in the relevant sections at 10 CFR part 429.
    In the June 2021 NOPR, DOE proposed to replace the term ``rated 
lifetime for general service incandescent lamps'' with the term 
``lifetime.'' With respect to an incandescent lamp, this would mean the 
length of operating time between first use and failure of 50 percent of 
the sample units (as specified in 10 CFR 429.27 and 10 CFR 429.38), 
determined in accordance with the test procedures described in appendix 
R. In proposing this definition for the term ``lifetime'', DOE proposed 
to remove the term ``rated'' from the current term ``rated lifetime for 
general service incandescent lamps'' to maintain consistency with DOE's 
proposal to remove the term ``rated'' from instances of ``rated 
lifetime'' in the relevant sections of 10 CFR 429.27. Additionally, 
because the term ``lifetime'' rather than ``lifetime for general 
service incandescent lamps'' is used in 10 CFR 429.27, DOE also 
proposed to remove the phrasing ``for general service incandescent 
lamps'' from the defined term. Id.
    In its comments, NEMA agreed with the proposed modifications to 
definitions for ``lifetime'' and ``rated wattage.'' (NEMA, No. 12 at p. 
5) For the reasons discussed in the June 2021 NOPR and in the preceding 
paragraphs, DOE is making clarifying amendments to the definitions of 
``rated wattage'' and ``lifetime for general service incandescent 
lamp'' and changing the latter term to ``lifetime'' as proposed in the 
June 2021 NOPR.
    In the provisions for determining the represented value of rated 
wattage for GSFLs, GSILs, and IRLs, in the June 2021 NOPR, DOE proposed 
to change any current references of ``rated lamp wattage'' to ``rated 
wattage'' for consistency within 10 CFR part 429 and to conform to the 
relevant term used in the energy conservation standards in 10 CFR 
430.32. 86 FR 29888, 29904. DOE received no comments on the proposed 
change. In this final rule, as proposed in the June 2021 NOPR, DOE is 
amending ``rated lamp wattage'' to ``rated wattage.''
    In the June 2021 NOPR, in the provisions for determining the rated 
wattage of GSILs, DOE proposed to change from using a two-tailed 
confidence interval to a one-tailed confidence interval when 
determining the 95-percent upper confidence limit. 86 FR 29888, 29904. 
A two-tailed confidence interval test is typically utilized to 
determine whether a set of results could be either higher or lower, 
while a one-tailed confidence interval test is typically utilized to 
determine whether a set of results are going in one specific direction 
(i.e., either higher or lower). All represented values of lamp metrics 
required by DOE are either the greater of or lower of the mean or the 
upper/lower confidence limit of the results--depending on how the 
consumer may value that metric. (For example, where lower values are 
favored, such as wattage, the represented value is greater of the mean 
or upper confidence limit of the results). A represented value of rated 
wattage for a GSIL is the greater of the mean or the upper 95-percent 
confidence limit. 10 CFR 429.27(a)(2)(iii) Because DOE is interested in 
the greater value from the tested results for wattage, a one-tailed 
confidence interval (which indicates whether results are going higher 
or lower), rather than two-tailed confidence interval test is 
appropriate.
    In its comments, NEMA agreed with the proposal to base the 95 
percent upper confidence limit for input power on the one-tailed 
confidence interval. (NEMA, No. 12 at p. 5) For the reasons discussed 
in the June 2021 NOPR and in the preceding paragraphs, DOE adopts a 
one-tailed confidence interval to determine the 95-percent upper 
confidence limit as proposed in the June 2021 NOPR.
Definitions of IRL Types
    In the June 2021 NOPR, DOE proposed to update the definitions in 10 
CFR 430.2 for the bulged parabolic aluminized reflector (``BPAR''), 20/
8-inch reflector (``R20''), elliptical reflector (``ER''), and bulged 
reflector (``BR'') incandescent reflector lamps with references to the 
latest versions of the currently referenced industry standards. 86 FR 
29888, 29904. Additionally, DOE proposed definitions for reflector 
(``R'') and parabolic aluminized reflector (``PAR'') incandescent 
reflector lamps that reference ANSI C78.21-2011 (R2016). Id. 
Accordingly, DOE proposed to incorporate by reference ANSI C78.21-2011 
(R2016) and ANSI C78.79-2014 (R2020) for 10 CFR 430.2. Id. DOE received 
no comments on the proposed changes. In this final rule, DOE adopts the 
amendments to definitions of IRL types as proposed in the June 2021 
NOPR. DOE notes that, as specified in the proposed rule language, the 
definitions of ``R'' and ``PAR'' reference ANSI C78.79-2014 (R2020), 
not ANSI C78.21-2011 (R2016) as incorrectly stated in the section 
titled ``Definition of IRL Types'' in the preamble of the June 2021 
NOPR. 86 FR 29888, 2990. Additionally, DOE removes the duplicate 
definition of the term ``BR incandescent reflector lamp'' in 10 CFR 
430.2 and retains the definition of this term as proposed in the June 
2021 NOPR. This amendment is consistent with the statutory definition 
of ``BR incandescent reflector lamp'' in 42 U.S.C. 6291(55) and does 
not impact the scope of coverage for DOE's test procedure or energy 
conservation standards.
2. Sampling Requirements
    In the June 2021 NOPR, DOE proposed certain clarifying and 
organizational modifications to the sampling provisions in 10 CFR 
429.27(a). 86 FR 29888, 29904. First, to be consistent with sampling 
requirement language for other lamp types (i.e., CFLs and integrated 
LED lamps), DOE proposed to state explicitly that represented values 
and certified ratings must be determined in accordance with the 
sampling provisions described in 10 CFR part 429. Id. DOE also proposed 
to specify the same sample of units as the basis for representations 
for all metrics for each basic model. Id.
    Further, in the June 2021 NOPR, to reduce burden and confusion, DOE 
proposed to change the minimum sample size from 21 lamps to 10 lamps 
and to remove the requirement that a minimum of three lamps be selected 
from each month of production for a minimum of 7 out of a 12-month 
period. Id. Reducing the sample size from 21 to 10 lamps aligns with 
the sampling requirements of other lighting products (e.g., CFLs, 
integrated LED lamps). DOE proposed to remove the minimum of 7 out of 
12 months requirement because it has led to confusion among 
manufacturers who interpreted this to mean that DOE requires re-testing 
every calendar year. Further, selecting a few sample units from 
multiple months of the year can be difficult to coordinate and execute. 
In particular, if a manufacturer does not initially know the number of 
months in which it will produce the basic model, it would need to 
reserve lamps from each production month and later decide how many to 
test. 86 FR 29888, 29904-29905.
    DOE also proposed to eliminate the requirement to identify the 
production months of sample units in 10 CFR 429.27(c) by providing the 
production date codes and accompanying decoding schemes for all test 
units. Id. DOE tentatively concluded that this change would not require 
manufacturers to retest products. Id. Certifications based on 21 lamps 
would meet the proposed requirement to base certification on a minimum 
of 10 units. However, manufacturers would likely choose to test fewer 
lamps when they certify new

[[Page 53631]]

products and therefore save testing costs.
    In its comments, NEMA agreed with the proposed reduction in minimum 
sample size from 21 to 10, stating that GSFLs, IRLs, and GSILs are 
legacy technologies with less frequent production runs, making 
flexibility in sampling beneficial. NEMA also commented that DOE should 
consider sample size reductions in other product categories where 
sample size and testing cost can be non-trivial. (NEMA, No. 12 at p. 5)
    In response to NEMA's comment to reduce the sample size for other 
products generally, DOE notes that it is outside the scope of this 
rulemaking, which relates only to the test procedures and associated 
sampling and certification requirements for GSFLs, IRLs, and GSILs.
    In this final rule, as proposed in the June 2021 NOPR, DOE is 
reducing the minimum sample size from 21 to 10 for GSFLs, IRLs, and 
GSILs, and removing the associated requirement that a minimum of three 
lamps be selected from each month of production for a minimum of 7 
months out of a 12-month period. Also, as proposed in the June 2021 
NOPR, DOE is specifying that the same sample of units be used as the 
basis for representations for all metrics for each basic model. 
Additionally, as proposed in the June 2021 NOPR, DOE is explicitly 
stating that represented values and certified ratings must be 
determined in accordance with the sampling provisions described in 10 
CFR part 429. The expected cost savings from this adopted change are 
described in section III.G of this document.
    Because sample units would no longer have to be selected over a 12-
month period, DOE also proposed in the June 2021 NOPR to remove the 
requirement in 10 CFR 429.12(e)(2) to submit an initial certification 
report prior to or concurrent with the distribution of a new basic 
model for GSFLs and IRLs. 86 FR 29888, 29905. Instead, for GSFLs and 
IRLs, the complete certification report described in 10 CFR 429.12(b) 
would be required at that time. Id. DOE stated that it expected a 
manufacturer would complete the testing needed to submit a 
certification of compliance with standards prior to distribution in 
commerce, so a subsequent report would not be needed to reflect 
additional test results. Id.
    In its comments, NEMA agreed with the removal of initial 
certification report submissions for GSFLs and IRLs and noted that no 
new product offerings are expected that would require said reports. 
(NEMA, No. 12 at p. 6) In this final rule, DOE adopts its proposal in 
the June 2021 NOPR to remove initial certification report submissions 
for GSFLs and IRLs and to require that a complete test report be 
submitted prior to distribution in commerce of a basic model.
3. Represented Value Determinations
    Under the FTC lighting facts labeling requirement, manufacturers of 
GSILs and IRLs are required to include on the lamp packaging basic and 
consistent information, including lumen output, wattage, life, CCT, and 
costs of annual energy consumption. 16 CFR 305.23(b). In support of FTC 
labeling requirements for GSILs and IRLs, in the June 2021 NOPR, DOE 
proposed adding determinations for the represented values of life (in 
years), estimated annual energy cost (in dollars per year), CCT, 
wattage (for IRLs only), and initial lumen output (for IRLs only). 86 
FR 29888, 29905.
    Specifically, DOE proposed that represented values of CCT for GSILs 
and IRLs, and wattage for IRLs, be determined as the mean of the sample 
and initial lumen output for IRLs be determined using a lower 
confidence limit (``LCL'') calculation. Further, DOE proposed that 
represented values of life (in years) for GSILs and IRLs be determined 
by dividing the represented lifetime of these lamps, as determined by 
DOE requirements in 10 CFR part 429, by the estimated annual operating 
hours as specified by FTC in 16 CFR 305.23(b)(3)(iii). To support this 
calculation, DOE proposed that the lifetime for IRLs be determined as 
equal to or less than the median time to failure of the sample. DOE 
proposed that represented values of estimated annual energy cost (in 
dollars per year) for GSILs and IRLs be determined in accordance with 
FTC requirements (i.e., a usage rate of 3 hours per day, and 11 cents 
($0.11) per kWh), using the average initial wattage for the tested 
sample of lamps (see 16 CFR 305.23(b)(3)(ii)). Id.
    DOE's current test procedure for GSFLs includes measurement of 
wattage and CCT, and in this final rule DOE is adopting a test 
procedure for measuring CRI of IRLs (see section III.C.3 of this 
document). Therefore, in the June 2021 NOPR, DOE proposed to provide 
instructions that the represented values for wattage and CCT of GSFLs 
be determined as the mean of the sample, and CRI for IRLs be determined 
using a LCL calculation. Id.
    DOE also proposed to revise existing represented value 
determinations of initial lumen output for GSILs from a mean (average) 
to an LCL calculation; and determination of CRI for GSFLs from an LCL 
to an average calculation. Id. Finally, DOE proposed to remove language 
stating that lifetime is the length of operating time between first use 
and failure of 50 percent of the sample size. Id. Instead, DOE proposed 
to directly specify how failure of 50 percent of the sample is 
determined by stating that the represented value of lifetime is equal 
to or less than the median time to failure of the sample. Id. For an 
odd sample size, the median time to failure is simply the middle unit's 
time to failure. For an even sample size, it is the arithmetic mean of 
the time to failure of the two middle samples. DOE proposed this change 
would apply to both GSILs and IRLs. Id.
    DOE received no comments on these proposed changes. In this final 
rule, DOE adopts the aforementioned updates to determinations of 
represented values as proposed in the June 2021 NOPR.
4. Reporting Requirements
    To align the proposed amendments with the sampling requirements 
(see section III.D.2 of this document), in the June 2021 NOPR, DOE 
proposed removing the requirement to report production dates of units 
tested and removing ``12-month average'' from the description for 
GSFLs, IRLs, and GSILs. 86 FR 29888, 29905. Further, to align with the 
proposed method of referencing wattage (adopted in this final rule, see 
section III.D.1 of this document), DOE proposed clarifying the 
description of ``lamp wattage'' so that it instead reads as ``rated 
wattage'' for GSFLs, IRLs, and GSILs. Id. Additionally, to align with 
the proposed method of referencing lifetime (adopted in this final 
rule, see section III.D.1), DOE proposed clarifying the description of 
``average minimum rated lifetime'' so that it instead reads as 
``lifetime'' for GSILs. Id.
    DOE received no comments on these proposed changes. In this final 
rule, DOE adopts conforming amendments to the terminology in reporting 
requirements as proposed in the June 2021 NOPR.
5. Rounding Requirements
    In the June 2021 NOPR, for completeness and clarity, DOE proposed 
to specify rounding requirements for all represented values. 86 FR 
29888, 29906. DOE proposed to require rounding initial input power to 
the nearest tenth of a watt, initial lumen output to three significant 
digits, CRI to the nearest whole number, and lifetime to the nearest 
whole hour. Id. DOE proposed to modify the CCT rounding requirement to 
the nearest 100 Kelvin

[[Page 53632]]

rather than nearest 10 Kelvin. Id. DOE tentatively determined that 
these updates to rounding requirements would align with other DOE lamp 
test procedures such as CFLs and integrated LED lamps, and tentatively 
determined they provide the necessary level of precision for evaluating 
compliance with the applicable metric(s). Id.
    Additionally, DOE proposed to move the rounding requirements for 
lamp efficacy and CCT from appendix R to 10 CFR part 429. Id. DOE also 
proposed to consolidate all rounding provisions in a single paragraph 
in each of the relevant product-specific sections in 10 CFR part 429. 
Id.
    NEMA commented that it did not perceive any potential negative 
impact as a result of DOE's proposed rounding proposal, because it 
pertains to different functional parameters, and testing of GSFL, IRL, 
and GSIL technology is very mature and well understood. (NEMA, No. 12 
at p. 5)
    In this final rule, DOE adopts the aforementioned updates to 
rounding requirements as proposed in the June 2021 NOPR.

E. Amendments to 10 CFR 430.23(r)

    Test procedures and measurements for GSFLs, IRLs, and GSILs are 
specified in 10 CFR 430.23(r). Because they are also established in 
appendix R, DOE proposed in the June 2021 NOPR to remove calculations 
for determining annual energy consumption, lamp efficacy, CRI, and 
lifetime from 10 CFR 430.23(r). 86 FR 29888, 29906. Additionally, DOE 
proposed to reference appendix R in general rather than specifying 
sections, so that any future amendments to sections in appendix R do 
not require changes in 10 CFR 430.23(r). Id. Finally, DOE proposed to 
remove all references to annual energy consumption, as this metric is 
not required by DOE. DOE proposed to replace the current language in 10 
CFR 430.23(r) with a requirement to measure initial lumen output, 
initial input power, initial lamp efficacy, CRI, CCT, and time to 
failure in accordance with appendix R. Id.
    DOE received no comments regarding these proposed changes. DOE has 
determined that these changes to 10 CFR 430.23(r) improve the clarity 
of the GSFL, IRL, and GSIL test procedures. In this final rule, DOE 
adopts the amendments to 10 CFR 430.23(r) as proposed in the June 2021 
NOPR.

F. Conforming Amendments to Energy Conservation Standard Text at 10 CFR 
430.32

    In the June 2021 NOPR, to avoid confusion and align with the 
proposed new terminology for appendix R and 10 CFR 429.27, DOE proposed 
to modify certain terms related to the energy conservation standards 
for GSFLs, IRLs, and GSILs. 86 FR 29888, 29906. Specifically, the 
tables in 10 CFR 430.32(n)(6) and 10 CFR 430.32(x) provide the energy 
conservation standards for IRLs and GSILs, respectively, for which the 
wattage terms are measured values. For IRLs, DOE proposed to change 
``rated lamp wattage'' to ``rated wattage'' in 10 CFR 430.32(n)(6). 86 
FR 29888, 29906. Also, in existing footnote 1 in the table in 10 CFR 
430.32(n)(6), DOE proposed to specify the ``P'' in the minimum standard 
equation as ``rated wattage'' rather than ``rated lamp wattage.'' Id. 
For GSILs, DOE proposed to change the term ``maximum rate wattage'' to 
``maximum rated wattage'' in 10 CFR 430.32(x). Id.
    Further, for GSIL standards in 10 CFR 430.32(x), in the June 2021 
NOPR, DOE proposed to remove the term ``rated'' from ``rated lumen 
ranges'' and add an explanatory footnote to use the measured initial 
lumen output to determine the applicable lumen range. Id. Finally, DOE 
proposed to remove the term ``rate'' from ``minimum rate lifetime'' and 
add an explanatory footnote to use lifetime determined in accordance 
with 10 CFR 429.27 to assess compliance with this standard. Id.
    Additionally, DOE proposed to remove the lamp efficacy requirements 
for GSFLs manufactured after May 1, 1994, and November 1, 1995, and on 
or before July 14, 2012, listed in 10 CFR 430.32(n)(1) and for IRLs 
manufactured after November 1, 1995, and on or before July 14, 2012, 
listed in 10 CFR 430.32(n)(5). Id. New standards superseded these 
standards, and there are likely no units on the market to which they 
apply.
    Finally, DOE proposed to change the subparagraph numbering in 10 
CFR 430.32(x) as follows: 10 CFR 430.32(x)(1)(iii)(A) and (B) to 
respectively 10 CFR 430.32(x)(2) and (3); and subsequently renumber 10 
CFR 430.32(x)(2) and (3) to 10 CFR 430.32(x)(4) and (5). This would 
reduce any confusion that standards under these subparagraphs are 
applicable only for lamps that fall under 10 CFR 430.32(x)(1)(iii). Id.
    In its comments, NEMA agreed with the proposal to align 
terminology. (NEMA, No. 12 at p. 5) DOE has determined that these 
changes to 10 CFR 430.32 improve the clarity of the GSFL, IRL, and GSIL 
test procedures. As these changes are conforming amendments that 
generally align the terminology used in the energy conservation 
standards and test procedures, these amendments will not impact the 
stringency of the required energy conservation standard or compliance 
with the applicable energy conservation standards. In this final rule, 
DOE adopts the amendments to energy conservation standard text at 10 
CFR 430.32 as proposed in the June 2021 NOPR.

G. Test Procedures Costs and Impacts

    In this final rule, DOE amends the existing test procedures for 
GSIL, IRLs, and GSFLs by: (1) updating references to industry test 
standards to reflect current industry practices; (2) modifying, adding, 
and removing definitions to better align with the scope and test 
methods; (3) referencing specific sections within industry test 
standards for further clarity; (4) providing a test method for 
measuring CRI for incandescent lamps to support DOE requirements; (5) 
providing a test method for measuring lifetime of IRLs to support the 
FTC's labeling requirements; (6) clarifying test frequency and 
inclusion of cathode power in measurements for GSFLs; (7) decreasing 
the sample size and specifying all metrics for all lamps be measured 
from the same sample of units. In addition, this final rule aligns 
terminology across appendix R, the relevant sections of 10 CFR part 
429, 10 CFR 430.23(r), 10 CFR 430.32(n) and 10 CFR 430.32(x) and 
updates language for conciseness and clarity. DOE also updates certain 
represented value calculations and rounding requirements. DOE has 
determined that the test procedure as amended by this final rule would 
impact testing costs as discussed in the following paragraphs.
    DOE has determined that the updates to the GSFL, IRL, and GSIL test 
procedures will not increase test burden and would result in cost 
savings. The amendments adopted in this final rule primarily provide 
updates and clarifications for how to conduct the test procedures and 
do not add complexity to test conditions or setup. This final rule adds 
references to specific sections of industry test standards to provide 
precise direction when conducting the test procedures. Revisions to 
definitions and test conditions only clarify the test method. Further, 
the reorganization and alignment of terminology among relevant sections 
of the CFR improves readability and provides clarity throughout the 
sampling requirements, test procedure, and applicable energy 
conservation standards.
    The adopted provision specifying the frequency for testing and 
whether

[[Page 53633]]

cathode heat is included in measurements reflects the stated direction 
in industry test standards referenced by the current test procedures 
and also standard industry practice as verified by product submissions 
in DOE's Compliance Certification Database. Because DOE is specifying 
details that are already required or in use, DOE concludes that there 
are no costs incurred due to this final rule.
    Measurement of the CRI of incandescent lamps and measuring lifetime 
of incandescent reflector lamps is already required by DOE, EISA 2007, 
or FTC. As such, manufacturers already conduct this test for covered 
products. The method of measuring CRI has not changed substantively in 
over 20 years (the referenced industry test standard was last updated 
in 1995) and therefore the method of measurement used by manufacturers 
is likely substantively similar to the method adopted by this final 
rule. Further, the data required for CRI can be gathered via an 
integrating sphere at the same time the sphere is used to measure lumen 
output. Thus, the data to determine CRI can be gathered while measuring 
a quantity that is used in a metric already reported to DOE (i.e., lamp 
efficacy).
    Regarding lifetime, the FTC requires manufacturers to report life 
(in years) of IRLs on its Lighting Facts label. 16 CFR 305.23(b)(3)(ii) 
The lifetime test method used in support of the Lighting Facts label is 
likely substantively similar to the method adopted by DOE. The industry 
test method that describes measuring the lifetime of incandescent 
filament lamps is IES LM-49. Although IES LM-49 was updated in 2020, 
DOE concludes that changes in the updated version are only explicitly 
stating what is already practiced by test labs. Therefore, because 
industry is already conducting tests for the CRI of incandescent lamps 
and the lifetime of IRLs, and using methods that are substantively 
similar to the methods adopted in this final rule, DOE concludes that 
there are no costs incurred due to these proposed test methods. 86 FR 
29888, 29908.
    DOE is also allowing manufacturers to make voluntary 
representations of certain GSFLs. Manufacturers can voluntarily make 
representations at the high frequency settings specified in the 2016 
versions of ANSI C78.81 and ANSI C78.901 in accordance with test 
procedures specified in appendix R and sampling requirements in 10 CFR 
429.27. These values will not be used for compliance but rather would 
be in addition to values obtained for compliance and used by DOE for 
determining if and how standards for GSFLs should be amended in the 
future to accommodate testing at high frequency settings.
    DOE adopts updates to represented value calculations and rounding 
requirements in this final rule. These do not pose added burden as 
determination of represented values and rounding are actions 
manufacturers are already required to do when they annually certify 
basic models to DOE.
    In the June 2021 NOPR, DOE determined the cost savings associated 
with the proposal to change the minimum sample size to 10 lamps instead 
of 21 lamps. Because current certifications already must be based on a 
sample size of more than 10 units, products currently certified to DOE 
would not have to be retested as a result of this change. However, 
manufacturers would be able to use the new sampling requirements when 
new products are introduced and certified to DOE. Based on a review of 
submission dates for GSFL, IRL, and GSIL basic models in DOE's 
Compliance Certification Database, DOE determined the number of new 
model certifications during the period 2016-2018. An average of 196 
GSFL, 30 IRL, and 84 GSIL new models were certified over these years. 
The cost to test efficacy, CCT, and CRI at a third-party laboratory is 
approximately $90 per unit for a GSFL and approximately $75 per unit 
for an IRL or GSIL. Based on feedback from laboratories, a reduction in 
sample size would not change costs for lifetime testing for GSILs. 
Thus, in the June 2021 NOPR, DOE estimated the annual industry-wide 
savings for GSFLs due to reduced sample size requirements to be 
$193,710, for IRLs to be $24,475 and for GSILs to be $69,025. Id.
    NEMA commented that cost savings opportunities are small, as GSFLs, 
IRLs, and GSILs are highly mature technologies with declining sales. As 
an alternative NEMA encouraged DOE to reduce test costs for other, 
newer technology options sooner than has been proposed for this sector. 
(NEMA, No. 12 at p. 6)
    DOE notes that the scope of this rulemaking is to review and amend, 
as applicable, the test procedures for GSFLs, IRLs, and GSILs and the 
associated sampling and certification requirements. DOE has determined 
that for these covered products, the amendments to the sampling 
requirements adopted in this final rule will result in test cost 
savings as estimated in the June 2021 NOPR.
    DOE did not receive any comments on the cost estimates presented in 
the June 2021 NOPR. In this final rule, DOE maintains the conclusion 
that the adopted updates do not result in added test burden and the 
change to sample size results in cost savings as previously discussed 
in the June 2021 NOPR and in this document. Further, the amendments 
adopted in this final rule will not require changes to the designs of 
GSFLs, IRLs, or GSILs, and the adopted amendments will not impact the 
utility of such products or impact the availability of GSFL, IRL, or 
GSIL products. The adopted amendments will not impact the 
representations of GSFL, IRL, or GSIL energy efficiency. As such, the 
retesting of GSFLs, IRLs, or GSILs will not be required solely as a 
result of DOE's adoption of the proposed amendments to the test 
procedure.

H. Effective and Compliance Dates

    The effective date for the adopted test procedure amendment will be 
30 days after publication of this final rule in the Federal Register. 
EPCA prescribes that all representations of energy efficiency and 
energy use, including those made on marketing materials and product 
labels, must be made in accordance with an amended test procedure, 
beginning 180 days after publication of the final rule in the Federal 
Register. (42 U.S.C. 6293(c)(2)) EPCA provides an allowance for 
individual manufacturers to petition DOE for an extension of the 180-
day period if the manufacturer may experience undue hardship in meeting 
the deadline. (42 U.S.C. 6293(c)(3)) To receive such an extension, 
petitions must be filed with DOE no later than 60 days before the end 
of the 180-day period and must detail how the manufacturer will 
experience undue hardship. (Id.)

IV. Procedural Issues and Regulatory Review

A. Review Under Executive Orders 12866 and 13563

    Executive Order (``E.O.'') 12866, ``Regulatory Planning and 
Review,'' as supplemented and reaffirmed by E.O. 13563, ``Improving 
Regulation and Regulatory Review,'' 76 FR 3821 (Jan. 21, 2011), 
requires agencies, to the extent permitted by law, to (1) propose or 
adopt a regulation only upon a reasoned determination that its benefits 
justify its costs (recognizing that some benefits and costs are 
difficult to quantify); (2) tailor regulations to impose the least 
burden on society, consistent with obtaining regulatory objectives, 
taking into account, among other things, and to the extent practicable, 
the costs of cumulative regulations; (3) select, in choosing among 
alternative regulatory

[[Page 53634]]

approaches, those approaches that maximize net benefits (including 
potential economic, environmental, public health and safety, and other 
advantages; distributive impacts; and equity); (4) to the extent 
feasible, specify performance objectives, rather than specifying the 
behavior or manner of compliance that regulated entities must adopt; 
and (5) identify and assess available alternatives to direct 
regulation, including providing economic incentives to encourage the 
desired behavior, such as user fees or marketable permits, or providing 
information upon which choices can be made by the public. DOE 
emphasizes as well that E.O. 13563 requires agencies to use the best 
available techniques to quantify anticipated present and future 
benefits and costs as accurately as possible. In its guidance, the 
Office of Information and Regulatory Affairs (``OIRA'') in the Office 
of Management and Budget (``OMB'') has emphasized that such techniques 
may include identifying changing future compliance costs that might 
result from technological innovation or anticipated behavioral changes. 
For the reasons stated in the preamble, this final regulatory action is 
consistent with these principles.
    Section 6(a) of E.O. 12866 also requires agencies to submit 
``significant regulatory actions'' to OIRA for review. OIRA has 
determined that this final regulatory action does not constitute a 
``significant regulatory action'' under section 3(f) of E.O. 12866. 
Accordingly, this action was not submitted to OIRA for review under 
E.O. 12866.

B. Review Under the Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
preparation of a final regulatory flexibility analysis (``FRFA'') for 
any final rule where the agency was first required by law to publish a 
proposed rule for public comment, unless the agency certifies that the 
rule, if promulgated, will not have a significant economic impact on a 
substantial number of small entities. As required by Executive Order 
13272, ``Proper Consideration of Small Entities in Agency Rulemaking,'' 
67 FR 53461 (August 16, 2002), DOE published procedures and policies on 
February 19, 2003, to ensure that the potential impacts of its rules on 
small entities are properly considered during the DOE rulemaking 
process. 68 FR 7990. DOE has made its procedures and policies available 
on the Office of the General Counsel's website: www.energy.gov/gc/office-general-counsel.
    DOE reviewed this rule to amend the test procedures for GSFLs, 
IRLs, and GSILs under the provisions of the Regulatory Flexibility Act 
and the procedures and policies published on February 19, 2003. DOE 
certifies that this final rule will not have a significant impact on a 
substantial number of small entities. The factual basis for this 
certification is set forth in the following paragraphs.
    The Small Business Administration (``SBA'') considers a business 
entity to be a small business if, together with its affiliates, it 
employs less than a threshold number of workers specified in 13 CFR 
part 121. The size standards and codes are established by the 2017 
North American Industry Classification System (``NAICS'').
    GSFL, IRL, and GSIL manufacturers are classified under NAICS code 
335110, ``electric lamp bulb and part manufacturing.'' The SBA sets a 
threshold of 1,250 employees or fewer for an entity to be considered as 
a small business for this NAICS code. DOE conducted a focused inquiry 
into small business manufacturers of the GSFLs, IRLs, and GSILs covered 
by this rulemaking. DOE used available public information to identify 
potential small manufacturers. DOE accessed the Compliance 
Certification Database \37\ to identify basic models of GSFLs, IRLs, 
and GSILs. DOE then used other publicly available data sources, such as 
California Energy Commission's Modernized Appliance Efficiency Database 
System and company specific product literature, to create a list of 
companies that import or otherwise manufacture the GSFL, IRL, and GSIL 
models covered by this rulemaking. Using these sources, DOE identified 
a total of 20 distinct companies that import or manufacture GSFLs, 
IRLs, or GSILs in the United States.
---------------------------------------------------------------------------

    \37\ U.S. Department of Energy Compliance Certification 
Database, available at: www.regulations.doe.gov/certification-data/products.html#q=Product_Group_s%3A*.
---------------------------------------------------------------------------

    DOE then reviewed these companies to determine whether the entities 
met the SBA's definition of a ``small business'' as it relates to NAICS 
code 335110 and screened out any companies that do not offer products 
covered by this rulemaking, do not meet the definition of a ``small 
business,'' or are foreign owned and operated. DOE did not identify any 
small businesses that manufacture GSFLs, IRLs, or GSILs in the United 
States.
    In response to the June 2021 NOPR, NEMA stated that it is not aware 
of any small businesses that manufacture GSFLs, IRLs, and GSILs in the 
United States. (NEMA, No. 12 at p. 6)
    Because DOE identified no small businesses that manufacture GSFLs, 
IRLs, or GSILs in the United States, DOE concludes and certifies that 
the cost effects accruing from the final rule would not have a 
``significant economic impact on a substantial number of small 
entities,'' and that the preparation of a FRFA is not warranted.

C. Review Under the Paperwork Reduction Act of 1995

    Manufacturers of GSFLs, IRLs, and GSILs must certify to DOE that 
their products comply with any applicable energy conservation 
standards. To certify compliance, manufacturers must first obtain test 
data for their products according to the DOE test procedures, including 
any amendments adopted for those test procedures. DOE has established 
regulations for the certification and recordkeeping requirements for 
all covered consumer products and commercial equipment, including 
GSFLs, IRLs, and GSILs. (See generally 10 CFR part 429.) The 
collection-of-information requirement for the certification and 
recordkeeping is subject to review and approval by OMB under the 
Paperwork Reduction Act (``PRA''). This requirement has been approved 
by OMB under OMB control number 1910-1400. Public reporting burden for 
the certification is estimated to average 35 hours per response, 
including the time for reviewing instructions, searching existing data 
sources, gathering and maintaining the data needed, and completing and 
reviewing the collection of information.
    DOE is not adding to the certification or reporting requirements 
for GSFLs, IRLs, or GSILs in this final rule.
    Notwithstanding any other provision of the law, no person is 
required to respond to, nor shall any person be subject to a penalty 
for failure to comply with, a collection of information subject to the 
requirements of the PRA, unless that collection of information displays 
a currently valid OMB Control Number.

D. Review Under the National Environmental Policy Act of 1969

    In this final rule, DOE establishes test procedure amendments that 
it expects will be used to develop and implement future energy 
conservation standards for GSFLs, IRLs, and GSILs. DOE has determined 
that this rule falls into a class of actions that are categorically 
excluded from review under the National Environmental Policy Act of 
1969 (42 U.S.C. 4321 et seq.) and DOE's implementing regulations at 10 
CFR part 1021. Specifically, DOE has determined

[[Page 53635]]

that adopting test procedures for measuring energy efficiency of 
consumer products and industrial equipment is consistent with 
activities identified in 10 CFR part 1021, appendix A to subpart D, A5 
and A6. Accordingly, neither an environmental assessment nor an 
environmental impact statement is required.

E. Review Under Executive Order 13132

    Executive Order 13132, ``Federalism,'' 64 FR 43255 (August 4, 
1999), imposes certain requirements on agencies formulating and 
implementing policies or regulations that preempt State law or that 
have federalism implications. The Executive order requires agencies to 
examine the constitutional and statutory authority supporting any 
action that would limit the policymaking discretion of the States and 
to carefully assess the necessity for such actions. The Executive order 
also requires agencies to have an accountable process to ensure 
meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications. 
On March 14, 2000, DOE published a statement of policy describing the 
intergovernmental consultation process it will follow in the 
development of such regulations. 65 FR 13735. DOE examined this final 
rule and determined that it will not have a substantial direct effect 
on the States, on the relationship between the national government and 
the States, or on the distribution of power and responsibilities among 
the various levels of government. EPCA governs and prescribes Federal 
preemption of State regulations as to energy conservation for the 
products that are the subject of this final rule. States can petition 
DOE for exemption from such preemption to the extent, and based on 
criteria, set forth in EPCA. (42 U.S.C. 6297(d)) No further action is 
required by Executive Order 13132.

F. Review Under Executive Order 12988

    Regarding the review of existing regulations and the promulgation 
of new regulations, section 3(a) of Executive Order 12988, ``Civil 
Justice Reform,'' 61 FR 4729 (Feb. 7, 1996), imposes on Federal 
agencies the general duty to adhere to the following requirements: (1) 
eliminate drafting errors and ambiguity; (2) write regulations to 
minimize litigation; (3) provide a clear legal standard for affected 
conduct rather than a general standard; and (4) promote simplification 
and burden reduction. Section 3(b) of Executive Order 12988 
specifically requires that executive agencies make every reasonable 
effort to ensure that the regulation (1) clearly specifies the 
preemptive effect, if any; (2) clearly specifies any effect on existing 
Federal law or regulation; (3) provides a clear legal standard for 
affected conduct while promoting simplification and burden reduction; 
(4) specifies the retroactive effect, if any; (5) adequately defines 
key terms; and (6) addresses other important issues affecting clarity 
and general draftsmanship under any guidelines issued by the Attorney 
General. Section 3(c) of Executive Order 12988 requires Executive 
agencies to review regulations in light of applicable standards in 
sections 3(a) and 3(b) to determine whether they are met or it is 
unreasonable to meet one or more of them. DOE has completed the 
required review and determined that, to the extent permitted by law, 
this final rule meets the relevant standards of Executive Order 12988.

G. Review Under the Unfunded Mandates Reform Act of 1995

    Title II of the Unfunded Mandates Reform Act of 1995 (``UMRA'') 
requires each Federal agency to assess the effects of Federal 
regulatory actions on State, local, and Tribal governments and the 
private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531). 
For a regulatory action resulting in a rule that may cause the 
expenditure by State, local, and Tribal governments, in the aggregate, 
or by the private sector of $100 million or more in any one year 
(adjusted annually for inflation), section 202 of UMRA requires a 
Federal agency to publish a written statement that estimates the 
resulting costs, benefits, and other effects on the national economy. 
(2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to 
develop an effective process to permit timely input by elected officers 
of State, local, and Tribal governments on a proposed ``significant 
intergovernmental mandate,'' and requires an agency plan for giving 
notice and opportunity for timely input to potentially affected small 
governments before establishing any requirements that might 
significantly or uniquely affect small governments. On March 18, 1997, 
DOE published a statement of policy on its process for 
intergovernmental consultation under UMRA. 62 FR 12820; also available 
at www.energy.gov/gc/office-general-counsel. DOE examined this final 
rule according to UMRA and its statement of policy and determined that 
the rule contains neither an intergovernmental mandate, nor a mandate 
that may result in the expenditure of $100 million or more in any year, 
so these requirements do not apply.

H. Review Under the Treasury and General Government Appropriations Act, 
1999

    Section 654 of the Treasury and General Government Appropriations 
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family 
Policymaking Assessment for any rule that may affect family well-being. 
This final rule will not have any impact on the autonomy or integrity 
of the family as an institution. Accordingly, DOE has concluded that it 
is not necessary to prepare a Family Policymaking Assessment.

I. Review Under Executive Order 12630

    DOE has determined, under Executive Order 12630, ``Governmental 
Actions and Interference with Constitutionally Protected Property 
Rights'' 53 FR 8859 (March 18, 1988), that this regulation will not 
result in any takings that might require compensation under the Fifth 
Amendment to the U.S. Constitution.

J. Review Under Treasury and General Government Appropriations Act, 
2001

    Section 515 of the Treasury and General Government Appropriations 
Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most 
disseminations of information to the public under guidelines 
established by each agency pursuant to general guidelines issued by 
OMB. OMB's guidelines were published at 67 FR 8452 (Feb. 22, 2002), and 
DOE's guidelines were published at 67 FR 62446 (Oct. 7, 2002). Pursuant 
to OMB Memorandum M-19-15, Improving Implementation of the Information 
Quality Act (April 24, 2019), DOE published updated guidelines which 
are available at www.energy.gov/sites/prod/files/2019/12/f70/DOE%20Final%20Updated%20IQA%20Guidelines%20Dec%202019.pdf. DOE has 
reviewed this final rule under the OMB and DOE guidelines and has 
concluded that it is consistent with applicable policies in those 
guidelines.

K. Review Under Executive Order 13211

    Executive Order 13211, ``Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use,'' 66 FR 28355 
(May 22, 2001), requires Federal agencies to prepare and submit to OMB, 
a Statement of Energy Effects for any significant energy action. A 
``significant energy action'' is defined as any action by an agency 
that promulgated or is expected to lead to promulgation of a final 
rule, and that (1) is a significant regulatory action under Executive 
Order 12866, or any successor order; and (2) is likely to have a 
significant adverse

[[Page 53636]]

effect on the supply, distribution, or use of energy; or (3) is 
designated by the Administrator of OIRA as a significant energy action. 
For any significant energy action, the agency must give a detailed 
statement of any adverse effects on energy supply, distribution, or use 
if the regulation is implemented, and of reasonable alternatives to the 
action and their expected benefits on energy supply, distribution, and 
use.
    This regulatory action is not a significant regulatory action under 
Executive Order 12866. Moreover, it would not have a significant 
adverse effect on the supply, distribution, or use of energy, nor has 
it been designated as a significant energy action by the Administrator 
of OIRA. Therefore, it is not a significant energy action, and, 
accordingly, DOE has not prepared a Statement of Energy Effects.

L. Review Under Section 32 of the Federal Energy Administration Act of 
1974

    Under section 301 of the Department of Energy Organization Act 
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the 
Federal Energy Administration Act of 1974, as amended by the Federal 
Energy Administration Authorization Act of 1977. (15 U.S.C. 788; 
``FEAA'') Section 32 essentially provides in relevant part that, where 
a proposed rule authorizes or requires use of commercial standards, the 
notice of proposed rulemaking must inform the public of the use and 
background of such standards. In addition, section 32(c) requires DOE 
to consult with the Attorney General and the Chairman of the FTC 
concerning the impact of the commercial or industry standards on 
competition.
    The modifications to the test procedures for GSFLs, IRLs, and GSILs 
adopted in this final rule incorporate testing methods contained in 
certain sections of the following industry standards:
    (1) ANSI C78.21, ``American National Standard for Electric Lamps--
PAR and R Shapes,'' 2011 (R2016);
    (2) ANSI C78.79, ``American National Standard for Electric Lamps--
Nomenclature for Envelope Shapes Intended for Use with Electric 
Lamps,'' 2014 (R2020);
    (3) ANSI C78.81, ``American National Standard for Electric Lamps--
Double-Capped Fluorescent Lamps--Dimensional and Electrical 
Characteristics,'' 2016;
    (4) ANSI C78.375A, ``American National Standard for Electric 
Lamps--Fluorescent Lamps--Guide for Electrical Measures,'' 2014 
(R2020);
    (5) ANSI C78.901, ``American National Standard for Electric Lamps--
Single-Based Fluorescent Lamps--Dimensional and Electrical 
Characteristics,'' 2016;
    (6) ANSI C82.3, ``American National Standard for Electric Lamps--
Reference Ballasts for Fluorescent Lamps,'' 2016;
    (7) IES LM-9, ``ANSI/IES LM-9-2020--Approved Method: Electrical and 
Photometric Measurements of Fluorescent Lamps,'' 2020;
    (8) IES LM-20, ``ANSI/IES LM-20-20 Approved Method: Photometry of 
Reflector Type Lamps,'' 2020;
    (9) IES LM-45, ``ANSI/IES LM-45-20 Approved Method: Electrical and 
Photometric Measurements of General Service Incandescent Filament 
Lamps,'' 2020;
    (10) IES LM-49, ``ANSI/IES LM-49-20 Approved Method: Life Testing 
of Incandescent Filament Lamps,'' 2020;

    3. General Instructions
    3.1 When there is a conflict, the language of the test procedure 
in this appendix takes precedence over any materials incorporated by 
reference.
    3.2 Maintain lamp operating orientation throughout seasoning and 
testing, except that for T5 miniature bipin standard and high output 
GSFLs, follow Section 6.2.2 of IES LM-9-20. For all GSFLs, maintain 
lamp orientation when transferring lamps from a warm-up position to 
the photometric equipment per Section 6.2.4 of IES LM-9-20. Maintain 
lamp orientation at all other times, if practical.
    3.3 If a lamp breaks, becomes defective, fails to stabilize, 
exhibits abnormal behavior (such as swirling), or stops producing 
light prior to the end of the seasoning period, replace the lamp 
with a new unit. However, if a lamp exhibits one of the conditions 
listed in the previous sentence only after the seasoning period 
ends, include the lamp's measurements in the sample.
    3.4 Operate GSILs and IRLs at the rated voltage for incandescent 
lamps as defined in 10 CFR 430.2.
