Media Center: About the DLC

The DLC is a non-profit organization improving energy efficiency, lighting quality, and the human experience in the built environment. We collaborate with utilities, energy efficiency programs, manufacturers, lighting designers, building owners, and government entities to create rigorous criteria for lighting performance that keeps up with the pace of technology. Together, we’re creating solutions for a better future with better lighting.

Our mission is to achieve energy optimization by enabling controllability with a focus on quality, people, and the environment. The DLC’s many initiatives include three Qualified Products Lists for energy efficient lighting technology: Solid-State Lighting, Networked Lighting Controls (NLC), and Horticultural Lighting. We also offer an extensive library of resources, research, and tools that help accelerate the adoption of energy efficient, quality lighting solutions.
