Lighting - Fixtures

Regulated ballast in fixtures:

Lighting fixtures with regulated ballasts (and lamps) must first meet the current requirements of Canada's Energy Efficiency Regulations. This applies to most fixtures that contain ballasts that can operate 32WT8 – 4 foot rapid start fluorescent lamps.

Therefore, to be ENERGY STAR qualified in Canada, fixtures that operate 32W linear fluorescent lamps must:

  1. Meet the ballast regulatory requirements for Canada;
  2. Use ballasts registered with NRCan;
  3. Be listed on the U.S. ENERGY STAR product listThis link opens a new window..

ENERGY STAR® Qualifying Criteria for Residential Light Fixtures and Replacement GU-24 Base Integrated Lamps – Version 4.1

PDF version, 370 KB

A product must meet all of the identified criteria if it is to be labeled as ENERGY STAR by its manufacturer. The intent of ENERGY STAR for Residential Light Fixtures is to move consumers from traditional incandescent fixtures to fixtures that use high-quality fluorescent or other energy-efficient technologies, including motion-sensors and daylight-sensors for outdoor fixtures.

The references in this document to “safety” related standards do not necessarily reflect the equivalent “Canadian” mandatory requirements for Residential Light Fixtures sold in Canada. However, these products are require to meet mandatory Canadian safety standards when sold in Canada, and Natural Resources Canada does not have jurisdiction in this matter.

2) Qualifying Products

The ENERGY STAR Residential Light Fixture specification covers the requirements for indoor and outdoor light fixtures, recessed downlight retrofit kits and replacement GU-24 base integrated lamps intended primarily for residential type applications. For the purposes of this ENERGY STAR specification, residential applications include single-family and multi-family dwellings (such as houses and apartments), dormitories, public or military housing, assisted-living facilities, motels and hotels, and some light commercial applications.

Exclusion of magnetic ballasts
Indoor fluorescent fixtures that use magnetic ballasts cannot be ENERGY STAR qualified under this Version 4.1 specification. Only outdoor fixtures that use high intensity discharge (HID) lamps, such as metal halide and high pressure sodium, may continue to use magnetic ballasts.

Inclusion of decorative LEDs
EPA encourages the use of innovative light source technologies such as LEDs. LEDs used as decorative lighting elements in residential lighting fixtures and ceiling fan light kits are allowed as long as the total wattage of the LEDs does not exceed five (5) watts, the average LED system (LED and driver) efficacy is at least 20 lumens per watt, and the LED is used to supplement a primary light source that meets all of the applicable performance characteristics outlined in the Eligibility Criteria. This requirement applies to LED “hybrid” fixtures.

3) Energy-Efficiency Specifications

Only those products listed in Section 2 that meet the criteria provided in Annex A may qualify as ENERGY STAR. Specifications for qualifying indoor fixtures can be found in Table 1. Additional specifications for qualifying recessed downlight retrofit kits can be found in Table 1A. Specifications for qualifying outdoor fixtures can be found in either Table 2A – Outdoor Fixtures: Compliance Through Efficient Light Source or Table 2B – Outdoor Fixtures: Compliance Through Reduced Operating Time. Specifications for GU-24 based integrated lamps used in ENERGY STAR fixtures can be found in Table 3.

4) Qualification Process, Acceptable Sources of Documentation, Reference Standards & Required Documentation 1

The following section describes the steps required to qualify residential light fixtures and replacement GU-24 base integrated lamps as ENERGY STAR, provides information about acceptable sources of documentation, and states the testing standards and documentation required for performance characteristics.

Qualification Process

To qualify a residential lighting fixture as ENERGY STAR, it must be tested according to the protocol outlined below. Note: EPA and NRCan reserve the right to require additional documentation, at any time, in order to determine compliance with all performance characteristics.

  1. Participant must test qualifying products and obtain required documentation to meet the performance characteristics referenced in Annex A of this specification. Refer to the appropriate columns in Tables 1 through 3 to determine the reference standard and required documentation applicable to each performance characteristic.

    The following stipulations apply:

    • For multiple fixture models that use the same lamp/ballast combination, only one set of test results is required. For example, two fixtures that use the same lamp and ballast combination, but have different trim, lens and/or chassis need only be tested once.
    • For fixture models that may use different ballasts (either in terms of the type of ballast or manufacturer), each lamp/ballast combination must undergo testing and the test results must be submitted for qualification. For example, if a residential light fixture participant plans to use ballasts from several manufacturers in any one fixture, the fixture must be tested with each manufacturer's ballast.
    • For fixture models with one ballast type that can work with multiple fluorescent lamp types, the fixtures need only be tested with one lamp type. The lamp type must either be the one supplied with the fixture at shipment or, if a lamp is not supplied, one of the lamp types listed on the packaging. Please note that EPA and NRCan expect all lamps listed on the packaging to comply with the specification when operating on the fixture's ballast. To ease the burden on the manufacturer, however, test data need be submitted for only one lamp type operating on the fixture's ballast.

  2. Electronically submit a completed copy of the ENERGY STAR Residential Light Fixture Qualified Product Information (QPI) form, along with required documentation in the Supplemental Information Reporting (SIR) form, to the address listed on the QPI form. To obtain the current version of the QPI and SIR forms, visit the “Lighting” section of the U.S. ENERGY STAR Web site, select “Manufacturers,” and click on “Qualifying Product Information”.
Acceptable Sources of Documentation
  1. A variety of acceptable sources of documentation are referenced for each performance characteristic within Tables 1 through 3. For clarity, these sources are summarized below:

    • A test report from a laboratory accredited by NVLAP or one of its MRA signatories – Both public and private accredited laboratories may be used. NVLAP's MRA signatory partners include ILAC, APLAC, and NACLA. Note that if the laboratory used for the lumen output, CRI, CCT, or lamp life test is accredited by NVLAP or one of its MRA signatories, it must also have a scope of accreditation that includes the method of measurement reference standard for this performance characteristic. Participants should obtain from the laboratory both its certificate of accreditation and its scope of accreditation and submit them to ENERGY STAR.
    • An EPA-approved Platform Letter of Approval – These letters are provided from EPA to manufacturers who have pre-approved specific performance characteristics for their lamp and/or ballast. When using this type of documentation, Participants should obtain a copy of the applicable letter from the manufacturer and include it with the ENERGY STAR submittal.
    • EPA-approved documentation from an industry association – In certain instances, EPA has approved documentation from industry associations who take responsibility for specific performance characteristics of lamps and/or ballasts. When using this type of documentation, Participants should contact the industry association to obtain the EPA-approved documentation that is required for use with ENERGY STAR submittals. Note: Participants may use the NEMA-ALA Lamp and Ballast Matrices. as a source for obtaining required information to qualify fixtures.
    • A test report from an OSHA NRTL laboratory – Documentation for safety requirements must come from an OSHA NRTL laboratory. OSHA NRTL laboratories may also be used to obtain certain additional performance characteristics, as specified in Tables 1 through 3.
    • Manufacturer documentation – Documentation for certain performance characteristics (such as product packaging requirements) may come directly from the original equipment manufacturer.
  2. The information below may be used to locate an accredited testing facility:

    11. Participants must specify if their product contains amalgam mercury during the qualification submission process to be eligible for this requirement.
    12. Laboratory test results must be produced using each specific fixture that will be qualified.

5) Additional Quality Assurance Requirements

The following requirements outline a manufacturer-financed quality assurance system that allows for independent evaluation of ENERGY STAR qualified fixtures. These requirements went into effect with the Version 4.0 effective date of October 1, 2005. EPA or NRCan may request manufacturers to submit products for quality assurance testing as described below. EPA or NRCan reserve the right to modify these procedures based on experience gained in their implementation. The Procedures Manual. for the most recent round of this program is available on the U.S. ENERGY STAR RLF Partner Resources page.

For the most current information on this program, reference the Residential Light Fixtures Partner Resources page on the ENERGY STAR website.

A. Quality Assurance Testing (QA4)

EPA will select fixtures, platforms, and/or replacement lamps each year for quality assurance testing. The manufacturer of each selected product will be required to commission third-party testing of the specified fixture, lamp, or platform by a manufacturer-independent NVLAP accredited testing lab. The testing lab will procure three (3) samples of each fixture or ten (10) samples of each platform or replacement lamp on the open market (if possible). Specific testing details are outlined in the Procedures Manual. Each product must be tested for:

Performance Parameters

  • Efficacy
  • Lamp Start Time
  • Correlated Color Temperature
  • Color Rendering Index
  • Lamp Base Type
  • Lumen Maintenance
  • Maximum Ballast Operating Case Temperature (fixtures only)

Consumer Informational Parameters

  • Product Packaging
  • Fluorescent lamp labeling information as written on the lamp or lamp base (manufacturer designation that encompasses the lamp manufacturer name, wattage, correlated color temperature, and color rendering index)

NRCan additional testing
NRCan reserves the right to conduct compliance testing of the products qualified under the current criteria.

Schedule Requirements
The manufacturer must retain a qualified third-party NVLAP accredited testing lab within fourteen (14) business days of EPA notification. The laboratory must complete all initial testing (except lumen maintenance, which should be started but cannot be completed) within 19 calendar days of notification of test start date to EPA. For fixtures, testing on the first sample must be completed within 311 days of initial notification by EPA. If the second and third samples need to be tested, testing needs to be completed within 240 days of failure of the first sample. For platforms or lamps, testing on all ten samples must be completed within 311 days of initial notification by EPA.

For fixtures, if more than one sample fails to meet the same performance parameter of the ENERGY STAR specification, the fixture will be addressed under EPA's delisting protocol. For platforms or replacement lamps, if more than two out of ten samples fail to meet the same performance parameter of the ENERGY STAR specification, the platform or replacement lamps will be addressed under EPA's Standard Operating Procedure (SOP) for Underperforming Components (Lamps, Ballasts, or Drivers).

Note: EPA will select no more than two (2) lamp ballast platforms or replacement lamps from any given manufacturer per year. Having selected the platform or replacement lamp, EPA will then proceed with testing one specific fixture that contains each platform or replacement lamp; or initiate the Quality Assurance process on the items.

B. Third-Party Complaint Process

Any party who believes that a non-compliant fixture is using the ENERGY STAR mark may request that EPA investigate the fixture's compliance. This request must be accompanied by laboratory test reports or other evidence indicating that the product does not meet ENERGY STAR requirements. The third-party making the complaint shall remain anonymous in all communications between EPA and the manufacturer whose product is in question.

EPA will review the materials from the third-party; will notify the manufacturer of the complaint; and, if necessary, request a corrective action plan be submitted within seven (7) calendar days. Upon receipt and review of the corrective action plan, EPA will take one of the following actions:

  • Determine that the fixture is eligible to meet the ENERGY STAR requirements, or
  • Determine that the fixture is not qualified or not eligible to be qualified and either request additional information or take steps to remove the fixture from the ENERGY STAR Qualified Product List for a minimum of six months and/or ensure the manufacturer ceases use of the ENERGY STAR mark.

EPA reserves the right to terminate any partnership agreements with a manufacturer whose products repeatedly violate the specification.

6) Effective Date

The date that all ENERGY STAR qualified residential lighting fixtures must meet Version 4.1 is defined as the effective date of the agreement. The ENERGY STAR Version 4.1 Eligibility Criteria (aka Specification) for Residential Light Fixtures, which represents a change in requirements from Version 4.0 that affects only GU-24 based fixtures, came into effect on August 1, 2008.

  1. Qualifying and Labeling Products under the Version 4.1 Specification

    All products, including models originally qualified under Version 4.0 with a date of manufacture on or after August 1, 2008, must meet the new Version 4.1 requirements in order to use the ENERGY STAR mark on the product or in product literature on Participants promotional materials, on the Participant's website, or through Participant sales channels. (Note: Products qualified under Version 4.0 that employ lamp bases other than GU-24 will automatically qualify under Version 4.1 because the changes in the specification affect only GU-24 based products.) The date of manufacture is specific to each unit and is the date (e.g. month and year) on which a unit is considered to be completely assembled.
  2. Elimination of Automatic Grandfathering

    EPA does not allow grandfathering under this Version 4.1 specification. Therefore, any product sold, marketed, or identified by the manufacturing participant as ENERGY STAR must meet the current specification in effect at that time.

7) Future Specification Revisions

ENERGY STAR reserves the right to change the specification should technological and/or market changes affect its usefulness to consumers, industry, or the environment. In keeping with current policy, revisions to the specification will be arrived at through industry discussions.

While this document currently refers to test procedures for fluorescent and compact fluorescent technologies, as new technologies emerge that have equal or better performance to the levels proposed here, consistent with a technology neutral approach, EPA may amend the program requirements by adding additional test procedures.

Expiration of ENERGY STAR Qualification
During future specification revisions EPA may choose to require complete new test data (i.e., test data that has been obtained within the six months prior to submitting the fixture for re-qualification) and documentation for all performance characteristics in order for the fixture to remain ENERGY STAR qualified. New test data may be required for new, revised and/or existing ENERGY STAR performance characteristics.
