The Certified Lighting Subcomponent Database (CSD) is similar in purpose to the NEMA/ALA Lamp and Ballast Platform Matrix. The CSD will allow EPA-Recognized Certification Bodies (CBs) to upload make, model and certified performance data for tested lighting subcomponents including lamps, ballasts, GU24-based integrated (self-ballasted) lamps, and LED light engines. This performance data can be referenced when certifying a luminaire with ENERGY STAR. The NEMA/ALA matrix data can no longer serve this purpose because that data has not been certified by EPA-Recognized CBs, and may not have originated from EPA-Recognized Laboratories. Please note: subcomponents listed on the CSD are not themselves ENERGY STAR qualified. The CSD is intended to streamline the certification process; subcomponents are not required to be listed on the CSD to be employed in an ENERGY STAR certified luminaire. The CSD and additional information about it is available at www.energystar.gov/lightingsubcomponents.
