DesignLights Consortium® Energy Efficiency Requirements

DesignLights Consortium® (DLC) Energy Efficiency Requirements for Commercial Solid State Lighting (SSL) Products

The DesignLights Consortium® (DLC) is a voluntary certification initiative for LED technology requiring lighting products to comply with minimum performance standards in three critical areas:

• distribution,
• color,
• and longevity/stress.

Testing to DLC lighting requirements must be completed by an Accredited Laboratory, with test results submitted directly to the DLC by the manufacturer.

DLC certification is a utility-based initiative; numerous utilities nationwide base rebate programs on DLC standards for products including high bays, wall packs, lab lamps, roadway luminaires, retrofit-kits, decorative LEDs, and LED panels (such as refrigerator lights, T8’s, and panels used in commercial, industrial, or outdoor applications).
