What is the DLC and why does it matter

The Design Lights Consortium® Qualified Products List, or DLC QPL, is a qualification program created and administered by the nonprofit Northeast Energy Efficiency Partnerships (NEEP), whereby approved lights must pass certain energy efficacy criteria in addition to color, thermal and total flux requirements. For instance, the measured lumens per watt (efficacy) must be at a certain ratio. While the DLC was launched nearly 20 years ago, the DLC QPL began in 2008 and took off in 2009. By creating assurances for energy efficient standards for general lighting, the DLC QPL has been adopted by more than 80 energy efficiency programs through electrical utilities in North America.
