The DesignLights Consortium™ (DLC) is a project of Northeast Energy Efficiency Partnerships (NEEP), a regional non-profit founded in 1996. The DLC is dedicated to accelerating the widespread adoption of high-performing, energy efficient commercial lighting solutions. In collaboration with industry stakeholders, DLC defines high performance through technical requirements, facilitates thought leadership, and provides tools, resources, and technical expertise to members and industry.

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 requirements must be completed by an Accredited Laboratory, and test results submitted directly to the DLC by the manufacturer. DLC is a utility-based initiative; numerous utilities nationwide base rebate programs on DLC standards for products including Flood light, high bays, wall packs, roadway luminaires used in commercial, industrial, or outdoor applications.
