I. Authority and Background

    MHLFs are included in the list of ``covered products'' for which 
the U.S. Department of Energy (``DOE'') is authorized to establish and 
amend energy conservation standards and test procedures. (42 U.S.C. 
6295(a)(19)) DOE's energy conservation standards and test procedures 
for MHLFs are currently prescribed at 10 CFR 431.326 and 10 CFR 
431.324, respectively. The

[[Page 37686]]

following sections discuss DOE's authority to establish test procedures 
for MHLFs and relevant background information regarding DOE's 
consideration of test procedures for this equipment.

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 MHLFs, the subject of this document.\3\ (42 U.S.C. 
6292(a)(19) MHLFs contain metal halide lamp ballasts. Because the MHLF 
energy conservation standards in EPCA established a minimum efficiency 
for the ballasts incorporated into those fixtures, the test procedure 
requires measurement of metal halide lamp ballast efficiency. (42 
U.S.C. 6295(hh)(1)(A))
---------------------------------------------------------------------------

    \1\ All references to EPCA in this document refer to the statute 
as amended through the Energy Act of 2020, Pub. L. 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.
    \3\ Because of its placement in Part A of Title III of EPCA, the 
rulemaking for MHLFs is bound by the requirements of 42 U.S.C. 6292. 
However, because MHLFs are generally considered commercial 
equipment, as a matter of administrative convenience and to minimize 
confusion among interested parties, DOE adopted MHLF provisions into 
subpart S of 10 CFR part 431. 74 FR 12058, 12062 (March 23, 2009). 
Therefore, DOE will refer to MHLFs as ``equipment'' throughout the 
notice because of their placement in 10 CFR part 431. When the 
notice refers to specific provisions in Part A of EPCA, the term 
``product'' is used. The location of provisions within the CFR does 
not affect either their substance or applicable procedure.
---------------------------------------------------------------------------

    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 sets forth that test procedures for metal halide lamp ballasts 
shall be based on ANSI C82.6-2005.\4\ (42 U.S.C. 6293(b)(18))
---------------------------------------------------------------------------

American National Standard for Lamp Ballasts--Ballasts for High-
Intensity Discharge Lamps--Methods of Measurement. Approved February 
14, 2005.
---------------------------------------------------------------------------

    EPCA also requires that, at least once every 7 years, DOE evaluate 
test procedures for each type of covered product, including MHLFs, 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 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 \5\ and IEC Standard 62087 \6\ as applicable.

    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 procedure for MHLFs is codified at Title 10 of 
the Code of Federal Regulations (``CFR'') part 431, subpart S, Sec.  
431.324 (``Uniform test method for the measurement of energy efficiency 
and standby mode energy consumption of metal halide lamp ballasts'').
    The Energy Independence and Security Act of 2007 (Pub. L. 110-140; 
EISA 2007) amended EPCA, requiring DOE to establish test procedures for 
metal halide lamp ballasts based on the industry standard ANSI C82.6-
2005. (42 U.S.C. 6293(b)(18)) On March 9, 2010, DOE published a final 
rule establishing active mode and standby mode test

[[Page 37687]]

methods for MHLFs based on measuring ballast efficiency in accordance 
with ANSI C82.6-2005 (``March 2010 Final Rule''). 75 FR 10950. In the 
March 2010 Final Rule, DOE determined that ``off mode'' as defined by 
EPCA is not applicable to MHLFs because there is no condition in which 
the components of a MHLF are connected to the main power source and are 
not already in a mode accounted for in either active or standby mode. 
Id. at 10954-10955.
    On May 30, 2018, DOE published in the Federal Register a request 
for information seeking comments on the current test procedure for 
MHLFs. 83 FR 24680 (``May 2018 RFI''). On July 14, 2021, DOE published 
in the Federal Register a notice of proposed rulemaking (``NOPR'') 
proposing amendments to the current test procedure for MHLFs. 86 FR 
37069 (``July 2021 NOPR''). DOE held a public meeting related to the 
July 2021 NOPR on August 5, 2021.
    DOE received comments in response to the July 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 431.324, ``Uniform test 
method for the measurement of energy efficiency and standby mode energy 
consumption of metal halide lamp ballasts,'' as follows: (1) 
incorporating by reference new relevant industry standards as well as 
updating to latest versions of existing references; (2) revising 
definitions and reorganizing the content of the test procedure for 
better readability and clarity; (3) clarifying the selection of 
reference lamps to be tested with metal halide lamp ballasts; (4) 
specifying the light output level at which to test dimming ballasts in 
active mode; and (5) referencing IEC 63103:2020 and clarifying 
instructions for measuring the standby mode energy consumption of metal 
halide lamp ballasts.
    The adopted amendments are summarized in Table II.1 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 and 
adopted in this document will not alter the measured efficiency of 
MHLFs, 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 July 2021 NOPR, DOE received general comments 
regarding amended test procedures for MHLFs as well as more specific 
comments regarding proposed updates to industry standards and 
clarifications of test methods. The amendments being adopted in this 
final rule and comments are discussed in the following sections.

A. General Topics

    In response to the July 2021 NOPR, Signify stated that the test 
procedure proposed by DOE seems reasonably designed to measure the 
energy use or efficiency of MHLFs during a representative average use 
cycle or period of use. (Signify, No. 10 at p. 11) Signify also 
recommended, however, that DOE not change the test procedure for MHLFs 
because the existing one successfully communicates ballast energy 
efficiency and the accelerated market transition to light-emitting 
diode (``LED'') technology reduces any potential benefits of improving 
the test procedure. (Signify, No. 10 at p. 2) NEMA similarly stated 
that MHLFs are a highly mature technology for which sales are migrating 
to LED products; and that therefore, sweeping changes to the test 
procedure were not necessary. (NEMA, Public Meeting Transcript, pp. 27-
28)
    Regarding impact on measured values, Signify stated that the test 
procedure updates proposed in the July 2021 NOPR would not have a 
significant impact on measured values used for certifying compliance, 
with possible exceptions of proposals regarding standby mode power and 
ballast efficiency for dimming ballasts. (Signify, No. 10 at p. 9)
    DOE is publishing this final rule in satisfaction of the 7-year 
review requirement specified in EPCA, which requires DOE 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 finds that the adoption of 
applicable industry standards, updates to existing references of 
industry standards, and adoption of other clarifying amendments 
specified in the following sections will result in a more accurate test 
procedure and one that reflects industry best practices for testing 
MHLFs. Comments regarding the impacts on measured values resulting from 
amendments to standby mode testing and testing of dimming ballasts are 
discussed respectively, in sections III.F.2 and III.E.1.b. of this 
document.

B. Scope

    EPCA and DOE regulations define MHLF as a light fixture for general 
lighting application designed to be operated with a metal halide lamp 
and a ballast for a metal halide lamp. (42 U.S.C. 6291(a)(64) and 10 
CFR 431.322). Metal halide ballast is defined as a ballast used to 
start and operate metal halide lamps. (42 U.S.C. 6291(a)(62) and 10 CFR 
431.322). Metal halide lamp is defined as a high intensity discharge 
(``HID'') lamp in which the major portion of the light is produced by 
radiation of metal halides and their products of dissociation, possibly 
in combination with metallic vapors. (42 U.S.C. 6291(a)(63) and 10 CFR 
431.322).
    DOE is not changing the scope of equipment covered by its MHLF test 
procedure, or the relevant definitions, in this final rule.

C. Definitions

    DOE provides definitions concerning metal halide lamp ballasts and 
fixtures at 10 CFR 431.322. In the July 2021 NOPR, DOE proposed to 
define several terms in 10 CFR 431.322 pertaining to the proposed test 
specifications for reference lamps used in testing (see section III.E.1 
for greater detail). 86 FR 37069, 37079. Specifically, DOE proposed to 
define the term ``reference lamp'' as a lamp that meets the operating 
conditions of a reference lamp as defined by ANSI C82.9-2016. Id. DOE 
proposed to define ``quartz metal halide lamp'' as a lamp with an arc 
tube made of quartz materials, and ``ceramic metal halide lamp'' as a 
lamp with an arc tube made of ceramic materials. Id. Further, DOE 
proposed to amend the existing definition for the term ``ballast 
efficiency'' in 10 CFR 431.322 by removing clause 3 in the definition--
which references ``nominal system'' and ANSI C78.43--since the test 
procedure in its entirety outlines the system requirements when testing 
the ballast efficiency of a metal halide lamp ballast. Id. DOE also 
proposed to remove clauses 4 and 5 in the ``ballast efficiency'' 
definition, which provide input power and output power specifications 
for ballasts with a frequency of 60 Hz, and greater than 60 Hz, 
respectively. DOE proposed to move these requirements to the test 
procedure found in 10 CFR 431.324 because they describe the test 
method. Id.
    DOE received no comments regarding these modifications. For the 
reasons discussed in the July 2021 NOPR and in this paragraph, DOE is 
adopting these proposed changes to definitions in this final rule.

D. References to Industry Standards

    The MHLF test procedure currently incorporates by reference the 
2005 version of ANSI C82.6 (``ANSI C82.6-2005'') and the 2004 version 
of ANSI C78.43 (``ANSI C78.43-2004'').\8\ Industry periodically updates 
its testing standards to account for changes in technology,

methodology, developments in test instruments, and/or changes in 
industry practice. In the July 2021 NOPR, DOE identified updated 
versions of the industry standards incorporated by reference in the 
MHLF test procedure as shown in Table III.1 of this document. 86 FR 
37069, 37072.

    DOE compared these updated versions to those versions currently 
referenced by DOE's test procedure to determine to what extent, if any, 
incorporating by reference the latest industry standards would alter 
the measured energy efficiency or measured energy use, as determined 
under the existing test procedure, as required by EPCA. (42 U.S.C. 
6293(e)(1)) 86 FR 37069, 37073-37075. Specifically, DOE reviewed the 
2020 version of ANSI C82.6 (``ANSI C82.6-2015 (R2020)'') \9\ and the 
2017 version of ANSI C78.43 (``ANSI C78.43-2017'') \10\ for this 
purpose.

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

    ANSI C82.6-2005 is an industry standard that describes the 
procedures to be followed, and the precautions to be taken, in 
measuring the performance of ballasts that operate HID lamps. In the 
July 2021 NOPR, DOE identified the following differences between the 
2015 version of ANSI C82.6 and the 2020 version: The 2020 version of 
ANSI C82.6 includes a requirement that the ballast under test must be 
operated until it reaches equilibrium, thereby ensuring stable 
conditions for testing, which is already included in DOE's test 
procedure; the 2020 version of ANSI C82.6 provides greater flexibility 
by recommending the use of either a ``make-before-break'' or fast-
acting switch for the basic stabilization method when switching a 
reference lamp from a reference ballast circuit to a test ballast 
circuit; the 2020 version of ANSI C82.6 clarifies certain headings 
consistent with specifications in the DOE test procedure; the 2020 
version of ANSI C82.6 includes specifications pertaining to 
stabilization that reflect ``best practices;'' the 2020 version of ANSI 
C82.6 adds instrumentation requirements to improve consistency and 
repeatability of measured values, and that would not impact measured 
values; the 2020 version of ANSI C82.6 updates the list of pertinent 
measurements for electronic and magnetic ballasts; the 2020 version of 
ANSI C82.6 includes new sections that specify instrumentation to use 
and how to take certain measurements to improve consistency and 
repeatability; and reaffirms the equation for calculating ballast 
efficiency in DOE's regulations. 86 FR 37069, 37073-37074.
    ANSI C78.43 is an industry standard that sets forth the physical 
and electrical characteristics for single-ended metal halide lamps 
operated on 60 Hertz (``Hz'') ballasts. DOE tentatively determined that 
the changes in ANSI C78.43-2017 are mainly updates to certain lamp 
datasheets related to lamp designations, physical descriptions of 
lamps, and minor changes to test parameters. 86 FR 37069, 37074. The 
updated datasheets would provide characteristics for additional 
reference lamps to use for testing, which DOE tentatively determined 
reflect current industry practice. 86 FR 37069, 37075.
    In its review of the updated versions of ANSI C82.6 and ANSI 
C78.43, DOE tentatively determined that the changes would not result in 
a change in measured values or test burden. DOE proposed to reference 
ANSI C82.6-2015 (R2020) and ANSI C78.43-2017 in the DOE test procedure.

* Note: Additionally, this final rule incorporates by reference ANSI
  C78.44-2016, ANSI C82.9-2016, and IEC 63103:2020 in the MHLF test
  procedure.

    In addition to updating existing references to industry standards 
in DOE's test procedure with the most recent versions, DOE proposed in 
the July 2021 NOPR to incorporate by reference additional industry 
standards related to the testing of MHLFs that were not already 
referenced in the test procedure. 86 FR 37069, 37075-37076. 
Specifically, DOE proposed to incorporate by reference ANSI C78.44-2016 
\11\ to provide the physical and electrical characteristics for testing 
with double-ended metal halide lamps, ANSI C82.9-2016 \12\ to provide 
the definition of a reference lamp and IEC 62301:2011 for the 
measurement of standby mode energy consumption. Id. DOE tentatively 
determined that the inclusion of ANSI C78.44-2016 would ensure that 
necessary specifications are being provided for testing metal halide 
ballasts that operate double-ended metal halide lamps. Id. DOE 
tentatively determined that industry already adheres to stipulations 
for reference lamps as specified in ANSI C82.9-2016. Id. Regarding 
standby mode, DOE noted that it developed the standby mode test method 
to be consistent with the industry standard IEC 62301:2005, but also 
through reference to ANSI C82.6-2005. 86 FR 37069, 37076. DOE 
tentatively determined to directly incorporate by reference the most 
recent version, IEC 62301:2011. Id.

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

    In the July 2021 NOPR, DOE requested comment on its proposal to 
incorporate by reference ANSI C82.6-2015 (R2020), ANSI C78.43-2017, 
ANSI C78.44-2016, ANSI C82.9-2016, and IEC 62301:2011 in the MHLF test 
procedure. 86 FR 37069, 37085.
    Signify expressed support for incorporating by reference ANSI 
C82.6-2015 (R2020), ANSI C78.43-2017, ANSI C78.44-2016, and ANSI C82.9-
2016, stating that the standards are congruent with the latest ANSI C82 
committee consensus on the technical requirements and test procedures 
of metal halide ballasts and lamps. Signify stated that updated 
versions of ANSI C78.43-2017, ANSI C78.44-2016, and ANSI C82.9-2016 
offer more accurate descriptions than previous editions and

[[Page 37690]]

should not have a major impact on test results. (Signify, No. 10 at p. 
2, 3)
    In this final rule, as proposed in the July 2021 NOPR and based on 
the discussion in the preceding paragraphs and in the July 2021 NOPR, 
DOE incorporates by reference the industry standards ANSI C82.6-2015 
(R2020), ANSI C78.43-2017, ANSI C78.44-2016, and ANSI C82.9-2016. In 
this final rule, DOE is not adopting IEC 62301:2011 for the measurement 
of standby mode energy consumption as proposed in the July 2021 NOPR. 
In its place, DOE is adopting IEC 63103:2020 to replace references to 
ANSI C82.6 in the MHLF standby mode test method (see section III.F.2 of 
this document for further details). DOE has determined that, because 
these updates to industry standard references do not involve 
substantive changes to the test setup and methodology but rather are 
clarifications that align DOE's test procedures with latest industry 
best practices, they will not affect measured values.

E. Amendments to Active Mode Test Method

    In this final rule, as proposed in the July 2021 NOPR, DOE adopts 
clarifying modifications to the active mode test method specified in 10 
CFR 431.324. Specifically, DOE amends the test conditions and setup, as 
well as the test method for the measurement of ballast efficiency of 
MHLFs. DOE also amends the test procedure to specify that the language 
in 10 CFR 431.324 takes precedence over the industry standard in cases 
where there is a conflict between any referenced industry standard and 
the language of the test procedure as revised by this final rule.
    DOE has determined that, because the adopted amendments to the 
active mode test method do not involve substantive changes to the test 
methodology but rather clarifications, they will not affect measured 
values. DOE details the amendments to the active mode test method and 
discussion of comments in the following subsections.
1. Test Conditions and Setup
    Paragraph (b)(1)(i) (``Test Conditions'') of 10 CFR 431.324 
specifies test conditions and setup requirements applicable to active 
mode testing. In the July 2021 NOPR, DOE proposed to amend the test 
conditions and setup paragraph to more accurately reference industry 
standards and the relevant sections of those standards, provide 
direction for testing metal halide lamp ballasts that operate lamps of 
different wattages or lamp types, and specify testing of dimming metal 
halide lamp ballasts at maximum input power. 86 FR 37069, 37076. DOE 
also proposed to revise the heading of paragraph (b)(1)(i) from ``Test 
Conditions'' to ``Test Conditions and Setup'' and to redesignate it as 
paragraph (b)(2) of the revised 10 CFR 431.324 to align with proposed 
additions to paragraph (b) pertaining to test setup. Id. The specific 
amendments as proposed and finalized are discussed in further detail in 
the sections that follow.
a. General Test Conditions
    Paragraph (b)(1)(i) of 10 CFR 431.324 references Section 4.0, 
``General Conditions for Electrical Performance Tests,'' of ANSI C82.6 
for power supply, ballast test conditions, lamp position, lamp 
stabilization, and test instrumentation. In the July 2021 NOPR, DOE 
proposed to relocate lamp stabilization requirements from this 
paragraph to the test method paragraph, newly designated as paragraph 
(b)(3), because lamp stabilization is part of the test method rather 
than a test condition, and to better align the test procedure with the 
organization of the updated ANSI C82.6 standard. 86 FR 37069, 37076. 
(See section III.E.2.a of this document regarding changes to the 
stabilization method) Also within the redesignated test conditions 
paragraph (b)(2), DOE proposed to include specification that the 
circuits used for testing must be in accordance with the circuit 
connections set forth in Section 6.3 of ANSI C82.6. Id.
    DOE received no comments regarding these modifications. In this 
final rule, for reasons discussed in this section and in the July 2021 
NOPR, DOE adopts these changes as proposed.
b. Dimming Ballasts
    In the March 2010 Final Rule, DOE determined that active mode 
applies to a functioning ballast operating with any amount of rated 
system light output (i.e., greater than zero percent), and noted that 
if a ballast is dimmed (i.e., operating the light source at more than 
zero percent, but less than 100 percent), the lamp and the ballast are 
both still in active mode. 75 FR 10950, 10953. In the July 2021 NOPR, 
DOE tentatively determined that in the case of dimming ballasts, where 
input power can vary, a specification regarding how to test these 
ballasts is necessary. DOE proposed to specify that dimming metal 
halide lamp ballasts be tested at maximum input power. 86 FR 37069, 
37076.
    Signify expressed support for DOE's proposal to specify that 
dimming metal halide lamp ballasts be tested at maximum input power. 
(Signify, No. 10 at p. 4) Signify commented that magnetic metal halide 
ballasts should not be dimmed below 50 percent rated power because the 
lamp operation may become unstable, the lamp color may shift 
dramatically, and the lamp electrodes' sputtering rate may 
significantly decrease lamp lifetime. Signify further commented that 
while electronic metal halide ballasts can dim metal halide lamps below 
50 percent rated power, color shift and lifetime issues may remain. For 
these reasons, Signify stated that the best practical way to test 
dimming metal halide lamp ballasts is at full power. (Signify, No. 10 
at pp. 4-5, 5) Signify further stated that the proposed clarification 
to test dimming ballasts at maximum power could change measured values 
if manufacturers had previously tested ballasts at different dimming 
points. Signify stated, however, that testing at maximum power is 
appropriate practice. (Signify, No. 10 at p. 10)
    DOE appreciates information on the dimming characteristics of metal 
halide ballasts. In this final rule, DOE is specifying to test dimming 
ballasts at maximum input power, i.e., at a non-dimmed level. DOE's 
review of the market indicates that specification sheets for dimming 
metal halide lamp ballasts provide input power at 100 percent power 
level as well as at lower power levels. Therefore, DOE does not expect 
this specification to result in a change in measured values of 
representations. In this final rule, for reasons specified in preceding 
paragraphs and in the July 2021 NOPR, DOE amends the test procedure to 
specify that dimming metal halide lamp ballasts be tested at maximum 
input power.
c. Reference Lamps
    Reference lamps must be used for testing MHLF ballast efficiency. 
Based on responses on the May 2018 RFI, DOE confirmed that the 
availability of reference lamps for metal halide ballast testing is 
sufficient and, in the July 2021 NOPR, proposed several additions to 
the test conditions and setup paragraph of 10 CFR 431.324 to clarify 
the selection of metal halide lamps used in testing metal halide lamp 
ballasts. 86 FR 37069, 37076. ANSI C82.9-2016 provides definitions 
related to specific terms used in industry standards for HID lamps and 
ballasts. Thus, in the July 2021 NOPR, DOE proposed to specify that the 
metal halide lamps used for testing must meet the definition of a 
reference lamp as defined by ANSI C82.9-2016. In addition, ANSI C78.43-
2017 and ANSI C78.44-2016 specify the physical and electrical 
requirements that single-ended and double-ended

[[Page 37691]]

metal halide lamps operated on 60 Hz ballasts must meet to qualify as 
reference lamps. Therefore, DOE also proposed that the metal halide 
lamps used for testing must be within the acceptable range for a 
reference lamp of the rated values specified in ANSI C78.43-2017 and 
ANSI C78.44-2016 for single-ended metal halide lamps and double-ended 
metal halide lamps, respectively. Id.
    The definition of basic model for MHLFs states that basic models 
are rated to operate a given lamp type and wattage. 10 CFR 431.322. 
Therefore, as DOE noted in the July 2021 NOPR, metal halide ballasts 
capable of operating multiple lamp wattages currently fall within 
multiple basic models. 86 FR 37069, 37077. No specification regarding 
the reference lamp to be used in testing metal halide lamp ballasts, 
pertaining to either lamp wattage or lamp type, is provided in 10 CFR 
431.324. Thus, DOE proposed revisions to the test procedure to clarify 
the wattage and type of reference lamp to be used for testing. Id.
    DOE has identified metal halide lamp ballasts that may be able to 
operate lamps of different wattages (e.g., a ballast that can operate a 
70 W lamp or 100 W lamp). Section 6.18 of ANSI C82.6-2015 (R2020) 
states that, if a ballast can operate multiple lamp types, some 
(unspecified) regulations require that a ballast be tested with the 
highest lamp power specified by the manufacturer. Thus, in the July 
2021 NOPR, DOE proposed to add a requirement to 10 CFR 431.324 that 
metal halide lamp ballasts designated with ANSI codes corresponding to 
more than one lamp must be tested with the lamp having the highest 
nominal lamp wattage as specified in ANSI C78.43-2017 or ANSI C78.44-
2016, as applicable. 86 FR 37069, 37077.
    DOE also identified some ballasts that can operate both ceramic 
metal halide lamps and quartz metal halide lamps. Based on data 
collected for DOE's HID lamps final rule determination published on 
December 9, 2015 (80 FR 76355),\13\ DOE has determined that quartz 
metal halide lamps are more popular than ceramic metal halide lamps. In 
the July 2021 NOPR, DOE proposed to add a requirement to 10 CFR 431.324 
that ballasts designated with ANSI codes corresponding to both ceramic 
metal halide lamps (code beginning with ``C'') and quartz metal halide 
lamps (code beginning with ``M'') of the same nominal lamp wattage must 
be tested with the quartz metal halide lamp. 86 FR 37069, 37077.

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

    Signify expressed support for the proposal to test ballasts with 
lamps at the highest lamp wattage. Signify expressed no preference for 
testing with a quartz metal halide lamp over a ceramic metal halide 
lamp. (Signify, No. 10 at p. 5) Signify asserted that using a reference 
lamp ensures test result repeatability because the ballast load will 
always be operating at nominal voltage, whereas lamps used in practice 
undergo voltage variation as they age. (Signify, No. 10 at pp. 5-6)
    For the reasons discussed in the preceding paragraphs and in the 
July 2021 NOPR, in this final rule DOE adopts the proposed requirements 
that for ballasts capable of operating lamps of different wattages, 
select the reference lamp with the highest wattage; and for ballasts 
capable of operating quartz metal halide lamps and ceramic metal halide 
lamps of the same wattage, select the quartz metal halide lamp for 
testing.
2. Test Method
    In the July 2021 NOPR, DOE proposed to add paragraphs to the test 
method paragraph describing requirements for lamp stabilization, test 
measurements, and calculations. DOE also proposed to revise the heading 
of paragraph (b)(2) of 10 CFR 431.324 from ``Test Measurement'' to 
``Test Method'' and redesignate it as paragraph (b)(3) to align with 
the proposed revisions to paragraph (b). In addition, DOE proposed to 
add the ballast efficiency calculation contained in paragraph (b)(3) of 
existing 10 CFR 431.324 to the ``Test Method'' paragraph to further 
improve organization. 86 FR 37069, 37077. The specific amendments as 
proposed are discussed in further detail in the sections that follow.
a. Stabilization Criteria
    Paragraph (b)(1)(i) (``Test Conditions'') of 10 CFR 431.324 
contains instructions for lamp stabilization prior to testing 
(hereafter referred to as the ``basic stabilization method''). 
Paragraph (b)(1)(ii) of 10 CFR 431.324 (``Alternative Stabilization 
Method'') specifies an alternate stabilization method for cases where 
switching without extinguishing the lamp is impossible, or for low-
frequency electronic ballasts.
    In the July 2021 NOPR, DOE proposed to replace the explicit 
instructions for lamp stabilization in 10 CFR 431.324 with direct 
references to Sections 4.4.2 and 4.4.3 of ANSI C82.6-2015 (R2020) for 
the basic stabilization method and the alternative stabilization 
method, respectively. 86 FR 37069, 37077. DOE had adopted the explicit 
stabilization instructions in the March 2010 Final Rule based on then-
anticipated changes to the updated version of ANSI C82.6 provided by 
NEMA. Id. Because the explicit instructions for lamp stabilization in 
10 CFR 431.324 are now contained in ANSI C82.6-2015 (R2020), DOE 
proposed to reference the relevant sections, Sections 4.4.2 and 4.4.3. 
Id. DOE noted one difference in the basic lamp stabilization method in 
10 CFR 431.324 compared ANSI C82.6-2015 (R2020) and proposed to keep 
the specification in 10 CFR 431.324, as it is clearer and more 
practical to execute. Id. Specifically, ANSI C82.6-2015 (R2020) states 
that stabilization is determined by operating the lamp within 3 percent 
of its rated wattage in the specified ambient temperature until the 
electrical parameters ``cease to change.'' In 10 CFR 431.324, 
stabilization is reached when the lamp's electrical characteristics 
vary by no more than 3 percent in three consecutive 10- to 15-minute 
intervals. In the July 2021 NOPR, DOE tentatively determined that the 
verbiage ``cease to change'' in the updated ANSI stability criteria 
would be nearly impossible to meet, as electrical parameters are 
expected to change by a small percentage after each measurement. Id.
    Signify expressed support for retaining the basic stabilization 
method and adopting the alternative stabilization method described in 
ANSI C82.6-2015 (R2020). Signify added that the basic stabilization 
method has been successfully used to test magnetic metal halide lamp 
ballasts but cannot be used for electronic metal halide lamp ballasts, 
as stably transferring a lamp from a warmup (standby) ballast to an 
electronic ballast is difficult. (Signify, No. 10 at p. 6) Signify 
explained that when lamps on electronic ballasts are disconnected and 
transferred, or are in ``no lamp'' condition, they either power off 
until the power supply comes back on, or they power their lamp ignition 
circuit on again--neither of which are suitable for a stable transfer. 
Signify stated that the alternative stabilization method ensures 
repeatable ballast efficiency test results for electronic ballasts by 
avoiding multiple lamp reignitions. (Signify, No. 10 at p. 7)
    DOE reiterates that replacement of the basic stabilization method 
instructions with direct references to Section 4.4.2 of ANSI C82.6-2015 
(R2020) would maintain the same method as currently specified, as the 
current instructions are

[[Page 37692]]

consistent with ANSI C82.6-2015 (R2020), with the exception noted above 
regarding specific intervals for stabilization determination. As 
described in the preceding paragraphs and in the July 2021 NOPR, in 
this final rule DOE is replacing the explicit instructions for lamp 
stabilization in 10 CFR 431.324 with direct references to Sections 
4.4.2 and 4.4.3 of ANSI C82.6-2015 (R2020) for the basic stabilization 
method and the alternative stabilization method, respectively. DOE is 
also specifying for the basic stabilization method that stabilization 
is reached when the lamp's electrical characteristics vary by no more 
than 3-percent in three consecutive 10- to 15-minute intervals measured 
after the minimum burning time of 30 minutes, consistent with the 
proposal in the July 2021 NOPR.
b. Test Measurements
    Paragraph (b)(2) of 10 CFR 431.324 specifies that the ballast input 
power and lamp output power during operating conditions must be 
measured in accordance with the methods specified in Section 6.0 of 
ANSI C82.6-2005. In ANSI C82.6-2015 (R2020), Sections 6.1 and 6.8 
pertain specifically to measuring ballast input power, and Sections 6.2 
and 6.10 pertain specifically to measuring lamp output power. In the 
July 2021 NOPR, DOE proposed to remove the general reference to Section 
6 of ANSI C82.6 in 10 CFR 431.324 and to instead specifically reference 
Sections 6.1 and 6.8 of ANSI C82.6-2015 (R2020) for measuring ballast 
input power, and sections 6.2 and 6.10 of ANSI C82.6-2015 (R2020) for 
measuring lamp output power. DOE expected that these updates would 
further clarify the test procedure and not change measured values. 86 
FR 37069, 37077.
    DOE received no comments regarding these updates. For the reasons 
discussed in the July 2021 NOPR and in this paragraph, DOE is adopting 
these proposed changes in this final rule.
c. Calculations
    Paragraph (b)(3) of 10 CFR 431.324 (``Efficiency Calculation'') 
specifies that the measured lamp output power must be divided by the 
measured ballast input power to determine the percent efficiency of the 
ballast under test to three significant figures.
    In the July 2021 NOPR, DOE proposed to amend this instruction by 
referencing the specific sections in the DOE test procedure that 
specify how to measure ballast input power and ballast output (lamp) 
power. 86 FR 37069, 37078. Specifically, DOE proposed the amended 
instruction to state that the measured ballast output (lamp) power, as 
measured in paragraph (b)(2)(ii)(B), must be divided by the measured 
ballast input power, as measured in paragraph (b)(2)(ii)(B), to 
determine the percent efficiency of the ballast under test to three 
significant figures.
    DOE received no comments regarding these proposed amendments to the 
test procedure. For the reasons discussed in the July 2021 NOPR and in 
this paragraph, DOE is adopting these proposed changes in this final 
rule. DOE notes that in the amended test procedure, this instruction is 
specified in paragraph (b)(3)(iii)(A) of 10 CFR 431.324.

F. Amendments to Standby Mode Test Method

    Paragraph (c) of 10 CFR 431.324 (``Testing and Calculations-Standby 
Mode) specifies the procedure for measuring standby mode energy 
consumption. This paragraph explicitly states that the measurement of 
standby mode need not be performed to determine compliance with energy 
conservation standards for metal halide lamp fixtures at this time. 10 
CFR 431.324(c). That paragraph further states that this statement will 
be removed as part of the rulemaking to amend the energy conservation 
standards for metal halide lamp fixtures to account for standby mode 
energy consumption, and the specified procedure shall apply on the 
compliance date for such requirements. Id. However, all representations 
related to standby mode energy consumption of MHLFs made after 
September 7, 2010, must be based upon results generated under this test 
procedure. Id.
    In this final rule, as proposed in the July 2021 NOPR, DOE adopts 
clarifying modifications to the standby mode test method specified in 
10 CFR 431.324. 86 FR 37069, 37079. DOE has determined that, because 
the adopted amendments to standby mode test procedures do not involve 
substantive changes to the test methodology, they will not affect 
measured values. DOE details the amendments to the standby mode test 
method and discussion of comments in the following subsections.
1. Test Conditions and Setup
    In the July 2021 NOPR, DOE proposed to modify the general 
instructions of the standby mode test method found in existing 
paragraph (c) to clarify that standby mode energy consumption need only 
be measured for ballasts capable of operating in standby mode. DOE also 
proposed to state that the language in 10 CFR 431.324 would take 
precedence if there is a conflict between the industry standard, IEC 
62301:2011, proposed to be adopted through reference, and the language 
in the revised DOE test procedure. 86 FR 37069, 37079.
    DOE received no comments regarding these proposed amendments to the 
test procedure. For the reasons discussed in the July 2021 NOPR and in 
the preceding paragraph, DOE is adopting the changes to the test 
conditions and setup instructions as proposed.
    Both the active mode and standby mode test methods measure input 
power of the ballast. As such, for consistency within the test 
procedure and to reduce the test burden, in the July 2021 NOPR, DOE 
proposed to modify the test conditions and setup paragraph in the 
standby mode test method with the following directions: (1) test 
conditions and setup must be in accordance with the active mode test 
method, and (2) each ballast must be operated with a lamp as specified 
in the active mode test method, except that the use of a reference lamp 
is not required. 86 FR 37069, 37079. Because lamps are not turned on 
during the measurement of standby mode energy consumption, DOE 
tentatively determined that whether the lamp to which the ballast is 
connected is a reference lamp does not impact standby mode energy 
consumption measurements. In addition, DOE proposed to revise the 
heading ``Test Conditions'' of paragraph (c)(1) of existing 10 CFR 
431.324 to ``Test Conditions and Setup'', redesignated as paragraph 
(c)(2), to reflect these changes. Id.
    Signify expressed support for the proposed amendments with no 
additional comment. (Signify, No. 10 at p. 7)
    For the reasons discussed in the July 2021 NOPR and in preceding 
paragraphs, DOE adopts its proposal to reference the active mode test 
method section for the test conditions and setup of the standby mode 
test method, and to specify that each ballast must be operated with a 
lamp as specified in the active mode test method, except that the use 
of a reference lamp is not required.
2. Test Method and Measurement
    In the July 2021 NOPR, DOE proposed to add a new paragraph, 
designated as (c)(3), with the heading ``Test Method and Measurement,'' 
containing specific instructions related to the measurement of standby 
mode energy consumption. 86 FR 37069, 37079. DOE proposed to: (1) add 
instructions to turn on, at full light output, the lamp to which the 
ballast is connected to ensure the ballast is not defective and (2) 
require ballast stabilization and subsequent

[[Page 37693]]

measurement of standby mode energy consumption to be conducted 
according to Section 5 of IEC 62301:2011. Id.
    Signify stated that DOE's proposed instruction to require the lamp 
be turned on to ensure the ballast is not defective prior to measuring 
standby mode energy consumption is reasonable. Signify added that since 
a defective ballast may appear to be operating in standby mode with an 
unlit lamp, the ballast should be powered on before and after taking 
standby mode power measurements to verify it is operating properly. 
(Signify, No. 10 at p. 8)
    DOE determined that turning the lamp on prior to measurement is 
sufficient for verifying that the ballast is not defective--that it is 
providing the power supply necessary to operate the lamps, and that 
turning it on after the measurement is not necessary. This also aligns 
with DOE's standby mode test method for fluorescent lamp ballasts (see 
appendix Q).
    For the reasons discussed in the preceding paragraphs and in the 
July 2021 NOPR, in this final rule, DOE adopts its proposed 
instructions requiring the lamp be turned on prior to measurement to 
ensure the ballast is not defective prior to measuring standby mode 
energy consumption.
    Regarding DOE's proposal to stabilize and measure standby mode 
energy consumption in accordance with Section 5 of IEC 62301:2011, as 
discussed, EPCA directs DOE to establish test procedures to include 
standby mode energy consumption, taking into consideration the most 
current versions of Standards 62301 and 62087 of the International 
Electrotechnical Commission. (42 U.S.C. 6295(gg)(2)(A)) In establishing 
the standby test procedure for MHLFs, DOE developed the test procedure 
to be consistent with IEC Standard 62301. 75 FR 10950, 10959. IEC 
Standard 62087 applies only to audio, video, and related equipment, and 
does not apply to lighting products. IEC 62301:2011 does not 
specifically address lighting products but applies generally to 
household electrical appliances, which include lighting products. In 
order to develop a test method that would be familiar to metal halide 
lamp ballast manufacturers, DOE also referenced language and 
methodologies presented in ANSI C82.6-2005. Id.
    In the July 2021 NOPR, DOE proposed a standby mode test procedure 
that directly references IEC 62301:2011 to replace the test procedure 
based on IEC 62301 with references to ANSI C82.6. Specifically, DOE 
proposed to reference Section 5 of IEC 62301:2011 for stabilization and 
standby mode energy consumption measurements. 86 FR 37069, 37078-37079. 
DOE noted that ANSI C82.6 does not explicitly address measurements for 
standby mode, whereas IEC 62301:2011 provides instructions for 
measuring standby mode energy consumption of household electrical 
appliances. Id. In the May 2019 RFI, DOE requested comment on the 
potential impact of incorporating IEC 62301:2011. NEMA responded that 
IEC 62301:2011 is not applicable to high intensity discharge (``HID'') 
lamp ballasts. In response, in the July 2021 NOPR, DOE referred NEMA to 
section 1 of IEC 62301:2011 which states the standard is applicable to 
electrical products with certain rated voltages which would include 
metal halide lamp ballasts. Id. In the July 2021 NOPR, DOE tentatively 
determined that replacing the currently referenced industry standard 
(ANSI C82.6-2005) with one that addresses standby mode energy 
consumption (IEC 62301:2011) would improve clarity, better align with 
the requirements of EPCA and the standby mode test methods for other 
lighting products. 86 FR 37069, 37078-37079.
    China, Signify, and NEMA recommended that DOE adopt IEC 63103:2020 
rather than IEC 62301 for measuring standby mode power. (China, No. 9 
at p. 3; Signify, No. 10 at pp. 2-3; NEMA, Public Meeting Transcript, 
pp. 14-15) China stated that standby power measurements should adhere 
to IEC 63103:2020, as MHLFs are lighting devices, and asserted that IEC 
62301:2011 is for household appliances. (China, No. 9 at p. 3)
    Signify stated that MHLFs are not used in household applications 
and that IEC 63103:2020 has been specifically developed to measure low 
power modes, such as standby mode, of lighting devices and systems. 
Signify stated that the definition of standby power in IEC 63103:2020 
is ``standby mode [of lighting equipment] when the equipment is 
connected to a supply voltage with the illumination function off, while 
capable of being activated by an external trigger not being a trigger 
from a network,'' which better aligns with DOE's definition. (Signify, 
No. 10 at p. 3) Signify stated that IEC 63103:2020 includes more 
specific guidelines and clarifications for stabilizing MHLFs than IEC 
62301:2011 does, and that the ANSI C137 Lighting Systems Committee is 
in the process of adopting IEC 63103:2020 as an ANSI standard for 
similar reasons. (Signify, No. 10 at pp 3-4; 8-9)
    NEMA stated that when IEC 62301:2011 was the only standby mode 
testing standard, it was acceptable to use for MHLFs; but now that the 
lighting industry has written a standby testing standard (i.e., IEC 
63103:2020), it is more appropriate to use it. (NEMA, Public Meeting 
Transcript, pp. 14-15)
    As noted in the July 2021 NOPR, DOE proposed to reference Section 5 
of IEC 62301:2011 for stabilization and standby mode energy consumption 
measurements. 86 FR 37069, 37079. To evaluate commenters' 
recommendation to reference IEC 63103:2020 instead of IEC 62301:2011, 
DOE reviewed the method for stabilization and standby mode energy 
consumption measurements in the two standards in a line-by-line 
comparison. The method of stabilization and measurement are specified 
in Section 5.3 of IEC 62301:2011 and in Section 5.4 of IEC 63103:2020. 
Instructions in both these sections outline the same three options for 
stabilization and measurement of standby mode energy consumption: a 
direct meter reading method, an average reading method, and a sampling 
method. Sections in both standards describe the direct meter reading 
method as recording the instrument power reading; the average reading 
method as averaging power readings over a specified period or 
alternatively recording the accumulated energy consumption over a 
specified period and dividing by the period; and the sampling method as 
recording power measurements at regular intervals throughout the 
measurement period. Sections in both standards specify that the direct 
meter reading method shall only be used where the mode does not change 
and the power reading displayed is stable, and that results from the 
other two methods have precedence over this method. Both standards do 
not permit the average reading method for cyclic loads or limited 
duration modes and specify that the sampling method shall be used for 
cyclic or unstable modes and where there is doubt regarding the 
behavior of the test unit. Further, in each method, the steps for 
stabilizing and taking measurements are laid out in the same manner and 
use almost identical language. The only differences in the methods 
described in IEC 62301:2011 and IEC 63103:2020, shown in Table III.2, 
are the threshold at which the test unit is considered stable.

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

    As shown in Table III.2, IEC 63103:2020 specifies slightly less 
stringent stabilization thresholds than IEC 62301:2011 (e.g., 
specifying for the sampling method that the cumulative average of all 
data points in the second two thirds of the total time period must fall 
within a band of <plus-minus>1 percent, as opposed to a band of <plus-
minus>0.2 percent). DOE finds that these minor differences in stability 
criteria would not result in measurably different values of standby 
power between the two methods. As commenters have noted, IEC 63103:2020 
was specifically developed to measure standby mode of lighting devices, 
and thereby established stabilization thresholds more relevant to such 
products.
    Finally, as noted in preceding paragraphs, DOE requested comment on 
its consideration of referencing IEC 62301:2011 in the May 2019 RFI and 
its proposal to reference it in the July 2021 NOPR. 86 FR 37069, 37078-
37079. Because IEC 62301:2011 and IEC 63103:2020 provide the same test 
methods for stabilization and measurement, different only in certain 
stabilization thresholds, interested parties have had the opportunity 
to comment on the method of measuring standby mode in accordance with 
IEC 63103:2020. As commented by interested parties (as summarized in 
the preceding paragraphs), DOE has determined that the adoption of IEC 
63103:2020 better aligns with the lighting industry's best practices 
for measuring standby mode energy consumption.
    As directed by EPCA, DOE has taken into consideration IEC 62301 for 
the standby mode energy consumption test method (42 U.S.C. 
6295(gg)(2)(A)). As stated, the test method provided in IEC 63103:2020 
applicable to MHLFs is essentially the same test method as proposed by 
reference in IEC 62301. DOE has determined that the two test methods 
would produce equivalent results. As IEC 63103:2020 is specific to 
lighting, DOE has determined that it is the more appropriate industry 
standard to reference for measuring standby mode energy consumption of 
MHLFs. For these reasons, in this final rule DOE amends the MHLF test 
procedure to reference Section 5.4 of IEC 63103:2020 for stabilizing 
and measuring the standby mode energy consumption of MHLF ballasts.
    Regarding the implications of replacing the reference to ANSI 
C82.6-2005, Signify stated that the standby power test method specified 
by ANSI C82.6-2005 is very different from the proposed IEC 62301:2011 
method, and thus measured values could change. Signify stated the 
impact would be minimal, however, as few metal halide lamp ballasts 
operate in standby mode. Signify also noted that DOE has no efficiency 
standard for standby mode. (Signify, No. 10 at pp. 10-11)
    As noted by Signify and as discussed previously, DOE currently does 
not prescribe standards that incorporate standby mode energy 
consumption of MHLFs. Based on a review of MHLFs and metal halide lamp 
ballasts on the market, DOE has determined that manufacturers are not 
making representations of standby mode power consumption in public-
facing materials; therefore, amending the test procedure to reference 
IEC 63103:2020 (which, as discussed, produces results equivalent to IEC 
62301:2011) rather than ANSI C82.6-2005 will result in no impact for 
MHLF manufacturers.

G. Compliance Date

    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.)

H. Test Procedure Costs and Impacts

    In this document, DOE amends the existing test procedure for MHLFs 
by (1) incorporating by reference new relevant industry standards as 
well as updating to latest versions of existing references; (2) 
revising definitions and reorganizing the content of the test procedure 
for better readability and clarity; (3) clarifying the selection of 
reference lamps to be tested with metal halide lamp ballasts; (4) 
specifying the light output level at which to test dimming ballasts in 
active mode; and (5) referencing IEC 63103:2020 and clarifying 
instructions for measuring the standby mode energy consumption of metal 
halide lamp ballasts. DOE has determined that the test procedure as 
amended by this final rule would not impact testing costs as discussed 
in the following paragraphs.
    In the July 2021 NOPR, DOE tentatively determined that the proposed 
amendments to the MHLF test procedure would not be unduly burdensome to 
conduct and would

[[Page 37695]]

result in neither a reduction of nor an increase in future testing 
costs. 86 FR 37069, 37080. The proposed amendments update industry 
standard references of ANSI C78.43 from version 2004 to 2017 and ANSI 
C82.6 from version 2005 to 2020 and references three new standards: 
ANSI C78.44-2016 to incorporate industry-approved lamp characteristics 
for double-ended metal halide lamps; ANSI C82.9-2016 to incorporate 
industry-approved definition for reference lamp; and IEC 62301:2011 to 
incorporate an industry standard that is specific to standby energy 
consumption measurement. Id. In the July 2021 NOPR, DOE tentatively 
determined these updates only clarify requirements, and do not add 
complexity to test conditions/setup or add test steps. Id. In this 
final rule, DOE is adopting IEC 63103:2020 rather than IEC 62301:2011. 
As discussed in section III.F.2 of this document, these two standards 
specify slightly different stabilization thresholds but are expected to 
yield equivalent standby power measurement results. Therefore, DOE 
finds that its preliminary conclusions pertaining to IEC 62301:2011 
also apply to IEC 63103:2020 as adopted in this final rule.
    Further, DOE finds that the amendments, aside from updates and 
addition of industry standards, being adopted in this final rule and 
proposed in the July 2021 NOPR provide further clarification to DOE's 
test procedure for MHLF, do not substantively change the existing test 
methods and therefore do not impact test burden or testing costs. These 
amendments are clarifications regarding selection of reference lamps 
(see section III.E.1.c); of definitions (see section III.C); of light 
output level at which to test dimming ballasts (see section III.E.1.b); 
and testing standby mode energy consumption (see section III.F).
    Signify stated that adopting the test procedure updates will incur 
approximately $50,000 in additional costs through the need for a new 
National Voluntary Laboratory Accreditation Program (``NVLAP'') 
accreditation and to acquire equipment compatible with the proposed IEC 
standby power test method. Signify added that laboratories conducting 
the standby power test method will undergo a testing time increase of 
at least 90 minutes per unit. Signify stated that additional costs and 
test burden are unnecessary given the market transition to LED 
technology. (Signify, No. 10 at p. 11-12)
    As stated in the July 2021 NOPR, a laboratory gaining accreditation 
to test MHLFs according to the test procedure in 10 CFR 431.324 would 
be doing so voluntarily or as required by an entity other than DOE. 
Accreditation by NVLAP is not required by DOE under 10 CFR part 431 or 
10 CFR part 429 for the testing of MHLFs, and therefore does not factor 
into testing costs associated with DOE's test procedure. 86 FR 37069, 
37080. Regarding acquisition of test equipment compatible with the 
adoption of the IEC standard for standby mode energy consumption, DOE 
reviewed the instrumentation information provided in the IEC standards 
and did not identify the need for any equipment for power measurements 
that laboratories would not already have for taking power measurements 
of electrical products.
    In this final rule, DOE is specifying to stabilize the ballast and 
measure its standby mode energy consumption in accordance with Section 
5.4 of IEC 63103:2020 (see section III.F.2). DOE has determined that 
this amendment does not add testing time to the standby mode test 
method. Prior to this amendment the standby mode test method stated 
ballast test conditions shall be as specified in Section 4.0 of ANSI 
C82.6 and input power shall be measured as specified in Section 6.0 of 
ANSI C82.6. However, Section 4.0 of ANSI C82.6 provides specifications 
for lamp stabilization, not specifications, as provided in Section 5.4 
of IEC 63103:2020, for ballast stabilization in standby mode (i.e., 
lamp is turned off). DOE assumes that when using the previous standby 
test method any lab or manufacturer would follow best practices and 
stabilize the unit being tested before taking measurements. Section 5.4 
of IEC 63103:2020 provides three different step-by-step methods of 
determining stabilization and taking the final power measurement (see 
section III.F.2). These methods are not new and are almost the same 
ones employed in the industry standard for determining standby mode 
energy consumption for household electrical appliances, IEC 62301:2011. 
DOE finds that manufacturers, in accordance with best industry 
practices, would likely have used a method similar to the ones provided 
in Section 5.4 of IEC 63103:2020. Hence DOE has determined that 
referencing Section 5.4 of IEC 63103:2020 for stabilization and 
measurement of the standby mode energy consumption of the ballast does 
not result in additional testing time.
    In summary, DOE has determined that the amendments adopted in this 
final rule do not impact test burden or testing costs.

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 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.

[[Page 37696]]

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: energy.gov/gc/office-general-counsel.
    DOE has recently conducted a focused inquiry into small business 
manufacturers of the MHLFs covered by this rulemaking. DOE used 
available public information to identify potential small manufacturers. 
DOE accessed the Compliance Certification Database \14\ to create a 
list of companies that import or otherwise manufacture the MHLFs 
covered by this proposal.
---------------------------------------------------------------------------

    \14\ U.S. Department of Energy Compliance Certification 
Management System, available at: www.regulations.doe.gov/ccms.
---------------------------------------------------------------------------

    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. These size standards and codes established by the North 
American Industry Classification System (``NAICS'') and are available 
at https://www.sba.gov/document/support--table-size-standards. Metal 
halide lamp ballast manufacturing is classified under NAICS 335311, 
``Power, Distribution, and Specialty Transformer Manufacturing.'' The 
SBA sets a threshold of 750 employees or fewer for an entity to be 
considered as a small business for this category. MHLF manufacturing is 
classified under NAICS 335122, ``Commercial, Industrial, and 
Institutional Electric Lighting Fixture Manufacturing.'' The SBA sets a 
threshold of 500 employees or less for an entity to be considered as a 
small business for this category.
    To estimate the number of companies that could be small businesses 
that manufacture these ballasts, DOE conducted a market survey using 
publicly available information. DOE's research involved reviewing 
information provided by trade associations (e.g., the National 
Electrical Manufacturers' Association), information from individual 
company websites, market research tools (i.e., Hoover's reports) and 
DOE's certification and compliance database. DOE screened out companies 
that do not meet the definition of a ``small business'' or are 
completely foreign owned and operated. DOE identified five small 
businesses that produce metal halide lamp ballasts sold in the United 
States and can be considered small business manufacturers. For MHLFs, 
DOE identified approximately 54 small businesses that produce MHLFs 
sold in the United States and can be considered small business 
manufacturers.
    In the July 2021 NOPR, DOE tentatively concluded that the proposed 
amendments would not increase the industry cost of the existing test 
procedure (see section III.H) and would not have a ``significant 
economic impact on a substantial number of small entities,'' so the 
preparation of an IRFA is not warranted. 86 FR 37069, 37082.
    DOE received no comments on the impacts of the test procedure 
amendments proposed in the NOPR on small businesses.
    Therefore, DOE concludes 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. DOE has submitted a certification and supporting 
statement of factual basis to the Chief Counsel for Advocacy of the 
Small Business Administration for review under 5 U.S.C. 605(b).

C. Review Under the Paperwork Reduction Act of 1995

    Manufacturers of MHLFs 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 MHLFs. (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 amending the certification or 
reporting requirements for MHLFs 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 MHLFs. 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 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

[[Page 37697]]

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 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

[[Page 37698]]

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 Federal Trade Commission (``FTC'') concerning the 
impact of the commercial or industry standards on competition.
    The modifications to the test procedure for MHLFs adopted in this 
final rule incorporates testing methods contained in certain sections 
of the following commercial standards:
    (1) American National Standards Institute (``ANSI'') C78.43 (ANSI 
C78.43-2017), ``American National Standard for Electric Lamps--Single-
Ended Metal Halide Lamps,'' approved December 21, 2017.
    (2) ANSI C78.44 (ANSI C78.44-2016), ``American National Standard 
for Electric Lamps--Double-Ended Metal Halide Lamps,'' approved July 1, 
2016.
    (3) ANSI C82.6-2015 (R2020) (ANSI C82.6-2015 (R2020)), ``American 
National Standard for Lamp Ballasts--Ballasts for High-Intensity 
Discharge Lamps--Methods of Measurement,'' approved March 30, 2020.
    (4) ANSI C82.9 (ANSI C82.9-2016), ``American National Standard for 
Lamp Ballasts--High-Intensity Discharge and Low-Pressure Sodium Lamps--
Definitions,'' approved July 12, 2016.
    (5) International Electrotechnical Commission (``IEC'') 63103 (IEC 
63103), ``Lighting Equipment--Non-Active Mode Power Measurement'' 
(Edition 1.0, 2020-07).
    DOE has evaluated these standards and is unable to conclude whether 
it fully complies with the requirements of section 32(b) of the FEAA 
(i.e., whether it was developed in a manner that fully provides for 
public participation, comment, and review.) DOE has consulted with both 
the Attorney General and the Chairman of the FTC about the impact on 
competition of using the methods contained in these standards and has 
received no comments objecting to their use.

M. Congressional Notification

    As required by 5 U.S.C. 801, DOE will report to Congress on the 
promulgation of this rule before its effective date. The report will 
state that it has been determined that the rule is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).

N. Description of Materials Incorporated by Reference

    In this final rule, DOE incorporates by reference the test standard 
published by ANSI, titled ``American National Standard for Electric 
Lamps--Single-Ended Metal Halide Lamps,'' ANSI C78.43-2017. ANSI 
C78.43-2017 is an industry accepted test standard that specifies the 
physical and electrical requirements for single-ended metal halide 
lamps operated on 60 Hz ballasts. Specifically, the test procedure 
codified by this final rule references ANSI C78.43-2017 for 
characteristics of reference lamps that must be used when testing metal 
halide lamp ballasts. ANSI C78.43-2017 is readily available on ANSI's 
website at webstore.ansi.org/.
    In this final rule, DOE also incorporates by reference the test 
standard published by ANSI, titled ``American National Standard for 
Electric Lamps--Double-Ended Metal Halide Lamps,'' ANSI C78.44-2016. 
ANSI C78.44-2016 is an industry accepted test standard that sets forth 
the physical and electrical requirements for double-ended metal halide 
lamps operated on 60 Hz ballasts. Specifically, the test procedure 
codified by this final rule references ANSI C78.44-2016 for 
characteristics of reference lamps that must be used when testing metal 
halide lamp ballasts. ANSI C78.44-2016 is readily available on ANSI's 
website at webstore.ansi.org/.
    In this final rule, DOE also incorporates by reference the test 
standard published by ANSI, titled ``American National Standard for 
Lamp Ballasts--Ballasts for High-Intensity Discharge Lamps--Methods of 
Measurement,'' ANSI C82.6-2015 (R2020). ANSI C82.6-2015 (R2020) is an 
industry accepted test standard that describes the procedures and the 
precautions to be taken in measuring performance of low-frequency 
ballasts (electromagnetic and electronic ballasts that operate at less 
than 400 Hz) for HID lamps. Specifically, the test procedure codified 
by this final rule references Sections of ANSI C82.6-2015 (R2020) for 
general testing conditions and methods for the measurement of ballast 
operating characteristics. ANSI C82.6-2015 (R2020) is readily available 
on ANSI's website at webstore.ansi.org/.
    In this final rule, DOE also incorporates by reference the test 
standard published by ANSI, titled ``American National Standard for 
Lamp Ballasts--High-Intensity Discharge and Low-Pressure Sodium Lamps--
Definitions,'' ANSI C82.9-2016. ANSI C82.9-2016 is an industry accepted 
standard that provides definitions related to specific terms related to 
HID lamps and ballasts. Specifically, the test procedure codified by 
this final rule references ANSI C82.9-2016 for defining reference lamps 
which are used when testing metal halide lamp ballasts. ANSI C82.9-2016 
is readily available on ANSI's website at webstore.ansi.org/.
    In this final rule, DOE also incorporates by reference the test 
standard published by IEC, titled ``Lighting Equipment--Non-Active Mode 
Power Measurement (Edition 1.0, July 2020),'' IEC 63103:2020. IEC 
63103:2020 is an industry accepted standard that describes measurements 
of electrical power consumption in standby mode, off mode, and 
networked standby mode for lighting equipment. Specifically, the test 
procedure codified by this final rule references Section 5.4 of IEC 
63103:2020 for testing standby mode energy consumption of metal halide 
lamp ballasts. IEC 63103:2020 is readily available on IEC's website at 
webstore.ansi.org.

4. Section 431.324 is revised to read as follows:


Sec.  431.324  Uniform test method for the measurement of energy 
efficiency and standby mode energy consumption of metal halide lamp 
ballasts.

    (a) Scope. This section provides test procedures for measuring, 
pursuant to EPCA, the energy efficiency of metal halide lamp ballasts. 
After July 25, 2022, and prior to December 21, 2022, any 
representations with respect to energy use or efficiency of metal 
halide lamp fixtures must be in accordance with the results of testing 
pursuant to this section or the test procedures as they appeared in 10 
CFR 431.324 as it appeared in the 10 CFR parts 200-499 edition revised 
as of January 1, 2022. On or after December 21, 2022, any 
representations, including certifications of compliance for metal 
halide lamp fixtures subject to any energy conservation standard, made 
with respect to the energy use or efficiency of metal halide lamp 
fixtures must be made in accordance with the results of testing 
pursuant to this section.
    (b) Active mode procedure--(1) General instructions. Specifications 
in referenced standards that are recommended, that ``shall'' or 
``should'' be met, or that are not otherwise explicitly optional, are 
mandatory. In cases where there is a conflict between any industry 
standard(s) and this section, the language of the test procedure in 
this section takes precedence over the industry standard(s).
    (2) Test conditions and setup. (i) The power supply, ballast 
conditions, lamp position, and instrumentation must all conform to the 
requirements specified in Section 4.0 of ANSI C82.6-2015 (R2020) 
(incorporated by reference; see Sec.  431.323).
    (ii) Airflow in the room for the testing period must be <=0.5 
meters/second.
    (iii) Test circuits must be in accordance with the circuit 
connections specified in Section 6.3 of ANSI C82.6-2015 (R2020).

[[Page 37700]]

    (iv) For ballasts designed to operate lamps rated less than 150 W 
that have 120 V as an available input voltage, testing must be 
performed at 120 V. For ballasts designed to operate lamps rated less 
than 150 W that do not have 120 V as an available voltage, testing must 
be performed at the highest available input voltage. For ballasts 
designed to operate lamps rated greater than or equal to 150 W that 
have 277 V as an available input voltage, testing must be conducted at 
277 V. For ballasts designed to operate lamps rated greater than or 
equal to 150 W that do not have 277 V as an available input voltage, 
testing must be conducted at the highest available input voltage.
    (v) Operate dimming ballasts at maximum input power.
    (vi) Select the metal halide lamp for testing as follows:
    (A) The metal halide lamp used for testing must meet the 
specifications of a reference lamp as defined by ANSI C82.9-2016 and 
the rated values of the corresponding lamp data sheet as specified in 
ANSI C78.43-2017 (both incorporated by reference; see Sec.  431.323) 
for single-ended lamps and ANSI C78.44-2016 (incorporated by reference; 
see Sec.  431.323) for double-ended lamps.
    (B) Ballasts designated with ANSI codes corresponding to more than 
one lamp must be tested with the lamp having the highest nominal lamp 
wattage as specified in ANSI C78.43-2017 or ANSI C78.44-2016, as 
applicable.
    (C) Ballasts designated with ANSI codes corresponding to both 
ceramic metal halide lamps (code beginning with ``C'') and quartz metal 
halide lamps (code beginning with ``M'') of the same nominal lamp 
wattage must be tested with the quartz metal halide lamp.
    (3) Test method--(i) Stabilization criteria--(A) General 
instruction. Lamp must be seasoned as prescribed in Section 4.4.1 of 
ANSI C82.6-2015 (R2020).
    (B) Basic stabilization method. Lamps using the basic stabilization 
method must be stabilized in accordance with Section 4.4.2 of ANSI 
C82.6-2015 (R2020). Stabilization is reached when the lamp's electrical 
characteristics vary by no more than 3-percent in three consecutive 10- 
to 15-minute intervals measured after the minimum burning time of 30 
minutes.
    (C) Alternative stabilization method. In cases where switching from 
the reference ballast to test ballast without extinguishing the lamp is 
impossible, such as for low-frequency electronic ballasts, the 
alternative stabilization method must be used. Lamps using the 
alternative stabilization method must be stabilized in accordance with 
Section 4.4.3 of ANSI C82.6-2015 (R2020).
    (ii) Test measurements. (A) The ballast input power during 
operating conditions must be measured in accordance with the methods 
specified in Sections 6.1 and 6.8 of ANSI C82.6-2015 (R2020).
    (B) The ballast output (lamp) power during operating conditions 
must be measured in accordance with the methods specified in Sections 
6.2 and 6.10 of ANSI C82.6-2015 (R2020).
    (C) For ballasts with a frequency of 60 Hz, the ballast input and 
output power shall be measured after lamps have been stabilized 
according to Section 4.4 of ANSI C82.6-2015 (R2020) using a wattmeter 
with accuracy specified in Section 4.5 of ANSI C82.6-2015 (R2020); and
    (D) For ballasts with a frequency greater than 60 Hz, the ballast 
input and output power shall have a basic accuracy of <plus-minus>0.5 
percent at the higher of either 3 times the output operating frequency 
of the ballast or 2.4 kHz.
    (iii) Calculations. (A) To determine the percent efficiency of the 
ballast under test, divide the measured ballast output (lamp) power, as 
measured in paragraph (b)(3)(ii) of this section, by the measured 
ballast input power, as measured in paragraph (b)(3)(ii) of this 
section. Calculate percent efficiency to three significant figures.
    (B) [Reserved]
    (c) Standby mode procedure--(1) General instructions. Measure 
standby mode energy consumption only for a ballast that is capable of 
operating in standby mode. Specifications in referenced standards that 
are recommended, that ``shall'' or ``should'' be met, or that are not 
otherwise explicitly optional, are mandatory. When there is a conflict, 
the language of the test procedure in this section takes precedence 
over IEC 63103 (incorporated by reference; see Sec.  431.323).
    (2) Test conditions and setup. (i) Establish and maintain test 
conditions and setup in accordance with paragraph (b)(2) of this 
section.
    (ii) Connect each ballast to a lamp as specified in paragraph 
(b)(2)(vi) of this section. Note: ballast operation with a reference 
lamp is not required.
    (3) Test method and measurement. (i) Turn on all of the lamps at 
full light output. If any lamp is not functional, replace the lamp and 
repeat the test procedure. If the ballast will not operate any lamps, 
replace the unit under test.
    (ii) Send a signal to the ballast instructing it to have zero light 
output using the appropriate ballast communication protocol or system 
for the ballast being tested.
    (iii) Stabilize the ballast prior to measurement using one of the 
methods as specified in Section 5.4 of IEC 63103.
    (iv) Measure the standby mode energy consumption in watts using one 
of the methods as specified in Section 5.4 of IEC 63103.
