Lighting for the future.

Thanks to the participation of our consortium, the DLC’s solid-state lighting program is home to the largest and most influential list of high-performing commercial lighting products in the world. We work in tandem with energy efficiency programs to improve both the energy savings potential and quality of light in the built environment. The SSL Qualified Products List improves both consumer confidence and sustainability of the industry as a whole through well-researched criteria for efficiency and quality created by our expert team and input from our stakeholders. Our rigorous vetting and review process to qualify for listing creates trust.
