I. Introduction
DOE established an early assessment review process to conduct a
more focused analysis that would allow DOE to determine, based on
statutory criteria, whether an amended test procedure is warranted. 10
Code of Federal Regulations (``CFR'') part 430 subpart C appendix A
section 8(a). This RFI requests information and data regarding whether
an amended test procedure would more accurately and fully comply with
the requirement that the test procedure produce results that measure
energy use during a representative average use cycle or period of use
for the product, and not be unduly burdensome to conduct. To inform
interested parties and to facilitate this process, DOE has identified
several issues associated with the currently applicable test procedures
on which DOE is interested in receiving comment. Based on the
information received in response to the RFI and DOE's own analysis, DOE
will determine whether to proceed with a rulemaking for an amended test
procedure.
If DOE makes an initial determination that an amended test
procedure would more accurately or fully comply with statutory
requirements, or DOE's analysis is inconclusive, DOE would undertake a
rulemaking to issue an amended test procedure. If DOE makes an initial
determination based upon available evidence that an amended test
procedure would not meet the applicable statutory criteria, DOE would
[[Page 23636]]
engage in notice and comment rulemaking before issuing a final
determination that an amended test procedure is not warranted.
A. Authority
The Energy Policy and Conservation Act, as amended (``EPCA''),\1\
among other things, 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.
These products include CFLKs, the subject of this document. (42 U.S.C.
6291(50), 42 U.S.C. 6293(b)(16)(A)(ii), 42 U.S.C. 6295(ff)(2)-(5))
---------------------------------------------------------------------------
\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).
\2\ For editorial reasons, upon codification in the U.S. Code,
Part B was redesignated Part A.
---------------------------------------------------------------------------
Under EPCA, DOE's energy conservation program consists essentially
of four parts: (1) Testing, (2) labeling, (3) Federal energy
conservation standards, and (4) certification and enforcement
procedures. Relevant provisions of EPCA 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).
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(a)-(c)) DOE may, however, grant waivers of Federal
preemption in limited instances for particular State laws or
regulations, in accordance with the procedures and other provisions set
forth under 42 U.S.C. 6297(d).
EPCA also requires that, at least once every 7 years, DOE evaluate
test procedures for each type of covered product, including CFLKs, 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)) DOE is publishing this RFI to collect
data and information to inform its decision to satisfy the 7-year-
lookback review requirement.
B. Rulemaking History
On December 24, 2015, DOE published a final rule (``December 2015
Final Rule'') making two key updates to its CFLK test procedure. 80 FR
80209. First, DOE updated the CFLK test procedure to require that
representations of efficacy, including certifications of compliance
with CFLK standards, be made according to the corresponding DOE lamp
test procedures, where they exist (e.g., for a CFLK with medium screw
base sockets that is packaged with compact fluorescent lamps
(``CFLs''), the CFLK test procedure references the DOE test procedure
for CFLs at 10 CFR 430.23(y)). 80 FR 80209, 80211. Second, DOE updated
the CFLK test procedure by establishing in a separate appendix, i.e.,
appendix V1, the test procedure for CFLKs packaged with inseparable
light sources that require luminaire efficacy testing (e.g., CFLKs with
integrated solid state lighting (``SSL'') circuitry) and for CFLKs
packaged with lamps for which DOE test procedures did not exist. 80 FR
80209, 80212. With these changes, the December 2015 Final Rule aligned
CFLK requirements for measuring efficacy of lamps and/or light sources
in CFLKs with current DOE lamp test procedures.
The December 2015 Final Rule also replaced references to superseded
ENERGY STAR requirements with the latest versions of industry standards
in appendix V, the test procedure for measuring system efficacy of the
lamp and ballast platform. Additionally, for ease of reference, the
final rule replaced references to ENERGY STAR requirements in existing
CFLK standards contained in 10 CFR 430.32(s) with the specific
requirements. 80 FR 80209, 80211. Further, in that final rule, DOE
determined that it accounts for standby mode energy consumption of
CFLKs under the efficiency metric for ceiling fans rather than under
the CFLK efficiency metric; and therefore, did not specify a standby
mode test procedure for CFLKs. 80 FR 80209, 80212.
Representations regarding CFLKs subject to the January 21, 2020
standards must be based on the amended test procedure, including
appendix V1. See 80 FR 80209, 80220 and 81 FR 580 (January 6, 2016).
II. Request for Information
DOE is publishing this RFI to collect data and information during
the early assessment review to inform its decision, consistent with its
obligations under EPCA, as to whether the Department should proceed
with an amended test procedure rulemaking, and if so, to assist in the
development of proposed amendments. Accordingly, in the following
sections, DOE has identified specific issues on which it seeks input to
aid in its analysis of whether an amended test procedure for CFLKs
would more accurately or fully comply with the requirement that the
test procedure produces results that measure energy use during a
representative average use cycle for the product, and not be unduly
burdensome to conduct. DOE also welcomes comments on other issues
relevant to its early assessment that may not specifically be
identified in this document.
The current DOE test procedure for CFLK can be found at 10 CFR part
430, subpart B, Appendix V and Appendix V1. All CFLKs manufactured as
of January 21, 2020 must be tested according to appendix V1. Because
appendix V is no longer applicable, DOE is considering removing it.
Accordingly, in the following sections, DOE focuses on identifying
issues as they pertain to Appendix V1.
Issue 1: DOE requests comment on removal of appendix V, the test
procedure required to be used for CFLKs with pin-based sockets that are
manufactured on or after January 1, 2007, and prior to January 21,
2020.
A. Scope and Definitions
Appendix V1 establishes the test requirements to measure the energy
efficiency of all CFLKs packaged with fluorescent lamps other than
compact fluorescent lamps or general service fluorescent lamps,
packaged with SSL products other than integrated light-emitting diode
(``LED'') lamps, or with integrated SSL circuitry. To support the test
procedure for CFLKs the following terms are defined in Appendix V1:
``CFLK with integrated SSL circuitry,'' ``covers,'' ``other (non-CFL
and non-GSFL) fluorescent lamp,'' ``other SSL products,'' and ``solid-
state Lighting (SSL).''
B. Test Procedure
The current DOE test procedure for CFLKs in Appendix V1 specifies
instructions for measuring the lamp efficacy or luminaire efficacy, as
applicable. Appendix V1 incorporates by reference IES LM-9-09 \3\ (2009
version) for testing ``other fluorescent lamps'' (i.e., not CFLs or
general service fluorescent lamps (``GSFLs'')) and IES LM-79-08 \4\
(2008 version) for testing
[[Page 23637]]
``other SSL products'' (i.e., not integrated LED lamps) and CFLKs with
integrated SSL circuitry. Appendix V1 references the industry standards
for test conditions and measurements. These referenced industry test
standards have been updated by industry since DOE last amended its test
procedures. IES LM-9-09 has been updated with a 2020 version \5\ (ANSI/
IES LM-9-20) and the 2008 version of IES LM-79 (IES LM-79-08) has been
updated with a 2019 version \6\ (ANSI/IES LM-79-19). In the following
sections, DOE requests information on how the changes in the updated
versions of these standards would impact DOE's test procedure for
CFLKs.

---------------------------------------------------------------------------
1. IES LM-9
IES LM-9 provides methods for taking electrical and photometric
measurements of fluorescent lamps. DOE's initial review indicates no
major changes in ANSI/IES LM-9-20 compared to IES LM-9-09 except for
updates to certain relevant references. Section 6.2 of IES LM-9-2020
updates its reference of IES LM-54, the industry standard for lamp
seasoning, from the 1999 version \7\ (IESNA LM-54-99) to 2020 version
\8\ (ANSI/IES LM-54-20). Section 7.0 of ANSI/IES LM-9-20 updates its
references of IES LM-78, the industry standard for measurements in an
integrating sphere, from the 2007 version \9\ (IESNA LM-78-07) to the
2020 version \10\ (ANSI/IES LM-78-20). These updates are discussed in

---------------------------------------------------------------------------
IES LM-54
DOE identified several changes in ANSI/IES LM-54-20 compared to the
IESNA LM-54-99. ANSI/IES LM-54-20 adds a section on physical
environment test conditions that cover topics such as keeping labs
clean and within the ambient temperature range; not subjecting lamps to
excessive vibration/shock; and using airflow to cool the seasoning
area. ANSI/IES LM-54-20 also adds a section on electrical test
conditions which includes instructions on frequency, voltage wave
shape, voltage regulation, basic lamp connection protocols, and setting
up an adjacent ground for fluorescent lamps. Additionally, ANSI/IES LM-
54-20 includes a new section on test preparation which addresses how to
handle and mark lamps. Finally, ANSI/IES LM-54-20 adds a statement
expressly stating that the orientation of the lamp during seasoning
should be maintained for the entire test.
Issue 2: DOE requests information and test data, if available, on
any potential differences in testing under ANSI/IES LM-54-20 referenced
in IES LM-9-20 and the resulting measurements of efficacy, as compared
to efficacy as measured under IESNA LM-54-99 currently referenced by
IES LM-9-09. Please specify the updates in ANSI/IES LM-54-20 compared
to IESNA LM-54-99 that can result in changes to measured efficacy
values and by how much the values will change.
IES LM-78
DOE identified several changes in ANSI/IES LM-78-20 as compared to
IESNA LM-78-07. ANSI/IES LM-78-20 includes a new section on taking
measurements with a spectroradiometer within a sphere. ANSI/IES LM-78-
20 also provides specific sections on 2[pi] and 4[pi] geometry. For
4[pi] geometry, ANSI/IES LM-78-20 states the total surface area of the
lamp should be less than 2 percent of the total area of the sphere
wall. ANSI/IES LM-78-20 also adds an explanation on using sphere
angular response distribution function (``SRDF'') to assess sphere
responsivity. Further the equation to compute luminous flux now
includes subtraction of dark/stray light, a ratio of spectral mismatch
correction factor to self-absorption factor, and the sphere angular
non-uniformity correction factor.
DOE also identified updates to specifications in the IESNA LM-78-
07. ANSI/IES LM-78-20 states the sphere diameter shall be 1.5 times the
length of a linear lamp whereas it was specified as 2 times the length
in the 2007 version. ANSI/IES LM-78-20 also states for the degree of
the spectral match to the V([lambda]) function, it is preferable that
the value of the photometer be less than 3 percent, whereas it was less
than 5 percent in IESNA LM-78-07. Throughout ANSI/IES LM-78-20 the term
spatial luminous intensity is replaced with angular luminous intensity.
Finally, in ANSI/IES LM-78-20, the uncertainty analysis section has
been condensed to a list of potential sources of errors and references
to other industry standards for guidance.
Issue 3: DOE requests information and test data, if available, on
any potential differences in testing under ANSI/IES LM-78-20 referenced
in section 7.0 of ANSI/IES LM-9-20 and the resulting measurements of
efficacy, as compared to efficacy as measured under IESNA LM-78-07
currently referenced by IES LM-9-09. Please specify the updates in
ANSI/IES LM-78-20 compared to IESNA LM-78-07 that can result in changes
to measured efficacy values and by how much the values will change.
Issue 4: DOE requests information and test data, if available, on
any potential differences in testing under ANSI/IES LM-9-20 and the
resulting measurements of efficacy, as compared to efficacy as measured
under IES LM-9-09 currently incorporated by reference. Please specify
the updates in ANSI/IES LM-9-20 compared to IES LM-9-09 that can result
in changes to measured efficacy values and by how much the values will
change.
Issue 5: DOE seeks comment on any differences in testing costs
associated testing under ANSI/IES LM-9-20 compared to IES LM-9-09.
2. IES LM-79
I ES LM-79 provides methods for taking electrical and photometric
measurements of SSL products. DOE's initial review indicates several
key changes in ANSI/IES LM-79-19 compared to IES LM-79-08. Regarding
testing conditions, ANSI/IES LM-79-19 changes the tolerance of ambient
temperature to +/- 1.2 degrees Celsius measured not more than 1.5
meters from the test lamp, whereas in IES LM-79-08, it specified +/- 1
degree Celsius and measured from not more than 1 meter.
For instrumentation, ANSI/IES LM-79-19 requires the alternating
current (``AC'') power analyzer to have a frequency range from direct
current (``DC'') to at least 100 kilohertz (``kHz'') and for products
with high-frequency components a frequency range of at least 1
megahertz (``MHz''). ANSI/IES LM-79-19 also adds current crest factor
capability requirements for the AC power supply. Regarding power supply
tolerances, the ANSI/IES LM-79-19 specifies: (1) The supplied frequency
to have a tolerance of +/- 2 hertz (``Hz'') from the prescribed
frequency; and (2) the AC voltage component of the DC regulated voltage
to be less than 0.5
[[Page 23638]]
percent root mean square (``RMS'') of the DC regulated voltage.
IES LM-79-08 required that the calibration uncertainties of
instruments for AC voltage and current be a minimum of 0.2 percent and
for the AC power meter be a minimum of 0.5 percent. ANSI/IES LM-79-19
replaces these specifications with expanded uncertainty minimums of:
(1) 0.4 percent for RMS AC voltage for 60 Hz sinusoidal waveform
measurements; (2) 0.6 percent for RMS AC current for 0.5 Hz to 1 kHz
range and 2 percent for 1 kHz to 100 kHz range; and (3) 1 percent for
active AC power in the 0.5 Hz to 1 kHz range and 2 percent in the 1 kHz
to 100 kHz range.
For test circuits, ANSI/IES LM-79-19 adds the following
specifications: (1) Use of separate sense leads to avoid voltage drops;
(2) resistance and capacitance of test circuit (excluding power supply)
to be less than respectively 0.5 ohms and 1.5 nanofarads; and (3) the
internal impedance of voltage measurement circuits (excluding the power
meter) to be at least 1 megaohm.
For electrical measurements, ANSI/IES LM-79-19 specifies the
tolerances intervals of +/- 0.5 percent for AC RMS voltage, +/- 0.2
percent for DC voltage and current. It also states optical and
electrical waveforms should be analyzed to ensure measurement equipment
is appropriate and addresses inrush currents \11\ and testing low
voltage products.
---------------------------------------------------------------------------
\11\ Some SSL products may experience inrush currents which are
high instantaneous currents that occur when the power supply is
turned on.
---------------------------------------------------------------------------
Regarding stability, ANSI/IES LM-79-19 states that to determine
stability three readings of light output and electrical power must be
taken at 10-minute intervals over 20 minutes. IES LM-79-08 required
three readings taken at 15-minute intervals over 30 minutes. ANSI/IES
LM-79-19 also clarifies that it is the average of the three
measurements taken chronologically that should be used to determine the
stabilization threshold. Additionally, unlike IES LM-79-08, ANSI/IES
LM-79-19 no longer allows the use of alternative stabilization methods
for measurements of a number of products of the same model.
Finally, ANSI/IES LM-79-19 condenses the section on the integrating
sphere method and directly references IES LM-78-17,\12\ the 2017
version of the industry standard for measurements in an integrating
sphere. Further, ANSI/IES LM-79-19 specifies that the spectroradiometer
system have a wavelength uncertainty within 0.5 nanometers. ANSI/IES
LM-79-19 also specifies that for 2[pi] geometry the total surface area
of the test lamp internal to the sphere should be no more than 1
percent of the total surface area of the sphere.
---------------------------------------------------------------------------
\12\ Illuminating Engineering Society of America, IES LM-78-17
Approved Method for Total Flux Measurement of Lamps Using an
Integrating Sphere. Approved January 9, 2017.
---------------------------------------------------------------------------
Currently, appendix V1 references section 2 through 9.2 of IES LM-
79-08. If the DOE proposes to adopt ANSI/IES LM-79-19, sections 4
through 6 and 7.2 would be referenced.
Issue 6: DOE requests information and test data, if available, on
any potential differences in testing under ANSI/IES LM-79-19 and the
resulting measurements of efficacy, as compared to efficacy as measured
under IES LM-79-08 currently incorporated by reference. Please specify
the updates in ANSI/IES LM-79-19 compared to IES LM-79-08 that could
result in changes to measured efficacy values and by how much the
values will change.
Issue 7: DOE seeks comment on any differences in testing costs
associated testing under ANSI/IES LM-79-19 compared to IES LM-79-08.
Issue 8: DOE specifically requests information and test data, if
available, on any potential differences in the measurement of efficacy
when using a goniophotometer instead of an integrating sphere.
Issue 9: DOE requests information on industry test procedures for
photometric and electrical measurements of non-integrated organic
light-emitting diode lamps or any other SSL products not covered under
ANSI/IES LM-79-19.
