The Certified Lighting Subcomponent Database (CSD)

Consistent with the ENERGY STAR Lighting Sunset the CSD is now retired.

The historical data contained in the database is for reference only. The data for these subcomponents are no longer considered certified under the ENERGY STAR program and may not be used for future ENERGY STAR certifications.

General Information

  • For the ENERGY STAR Luminaires specification, the Certified Subcomponent Database (CSD) supported certification of models by providing certified performance data for lighting subcomponents.
  • The use of the CSD was optional for luminaire partners. It was intended to streamline the certification process; subcomponents were not required to be listed on the CSD to be employed in an ENERGY STAR certified luminaire.
  • The CSD was designed to contain certified performance data for: lamps, ballasts, fluorescent lamp-ballast platforms, GU24 based self-ballasted compact fluorescent lamps and HID lamps, GU24 based LED lamps, and LED light engines.
  • The CSD was similar in purpose and function to the NEMA/ALA Lamp and Ballast Platform Matrix, but provided certified performance data required for certification of ENERGY STAR luminaires. The CSD can streamline the process of luminaire certification by providing partners’ makes, models and certified performance data of subcomponents. Depending on the type of luminaire, the subcomponents listed here may or may not meet the applicable requirements. In most instances, this approach to luminaire certification significantly reduced the luminaire partner’s testing burden, such that only limited additional testing was needed at the luminaire level (e.g., in situ temperature measurements and electrical safety testing).
  • LED arrays/modules, LED drivers and LED power supplies were not individually listed in the database, as no industry standard methods of measurement existed for measuring the performance of LED drivers.
  • The CSD contained fields for each applicable performance criterion in the ENERGY STAR Luminaires V2.2 specification. A complete list of these requirements for each subcomponent is described below.
  • The CSD also indicated when a subcomponent failed to meet at least one ENERGY STAR criteria of a luminaire or lamp during verification testing of a certified luminaire, lamp, ceiling fan with light kit, or ventilating fan with light kit. These subcomponents were identified in the “Linked to Failed Luminaire or Lamp” column. Partners using these subcomponents in their ENERGY STAR certified products were ultimately responsible for their product performance and worked with their suppliers and certification bodies to ensure that end-use products met ENERGY STAR requirements.

Listing Subcomponents on the CSD: Process

Performance for subcomponents listed on the CSD were certified to meet relevant requirements for use in ENERGY STAR certified luminaires.

Subcomponents in this database were not ENERGY STAR certified as a result of being listed. Subcomponents only certified for purposes of the CSD:

  • Could not carry any of the Program’s certification or promotional marks on the subcomponent, on subcomponent packaging, or in associated literature either printed or electronic.
  • Could not be referred to as ENERGY STAR certified, certified, rated, or approved.

Note: GU24-based integrated lamps that were ENERGY STAR certified could have appeared on both the CSD and the lamps certified product list.

Note: Questions about appropriate references to CSD listings in subcomponent marketing materials were to be directed to

Subcomponent Manufacturers:

To have subcomponents listed on the CSD, subcomponent manufacturers followed the third-party certification procedures and had subcomponents tested at an EPA-recognized laboratory, and the test data certified by an EPA-recognized certification body (CB). Please note, the data displayed only highlighted CSD products that met full certification.

  • Subcomponent partners' test labs provided the same test reports required by the Luminaires specification, and the sample sizes for subcomponents followed the required sample sizes in the specification. See Testing Requirements section below.
  • If the subcomponent met the Luminaires specification performance levels attributable to the subcomponent, the CB certified the subcomponent data for listing on the CSD.
  • When luminaire partners provided materials for ENERGY STAR certification, they were able to reference CSD listings for the performance data of subcomponents used in their luminaires.
  • The CSD listed performance data as entered by EPA-recognized certification bodies. Laboratory test reports themselves were not posted.

Certification Bodies:

  • CBs submitted certified performance data to EPA for listing on the CSD.
  • CBs reviewed subcomponent data from the CSD when reviewing a luminaire for certification to determine that it met the requirements for the specific type of luminaire to be certified.
  • Lifetime Testing: The luminaires specification allows for initial (conditional) certification of luminaires based on completion of minimum lamp lifetime testing requirements. This provision required that full lamp lifetime testing be completed, and requirements met, for full certification. In all instances where, subsequent to an initial CSD listing of a lamp or an initial luminaire certification, a certification body (CB) received lifetime testing results indicating that the product failed to meet rated lifetime (as indicated on product packaging), the CB was required within 2 business days to report this information as a subcomponent (lamp) or luminaire testing failure to
  • In order to list a subcomponent on the CSD, the CB ensured that it met the following luminaire requirements for the specific subcomponent, where applicable:
    • Transient protection;
    • Electrical safety as tested by an OSHA NRTL;
    • Electromagnetic and radio frequency interference;
    • Lighting toxics reduction;
    • Labeling language for mercury content; and
    • Warranty
