DLC Certification
DLC Certification DesignLightsConsort, DLC, is a consortium of public utility companies and regional energy efficiency agencies that are leaders in certifying the quality and performance of energy-efficient lighting.
DLC is a consortium of utility companies and regional energy efficiency agencies that lead the way in certifying the quality and performance of energy-efficient lighting. DLC certified products are used by utilities to promote high performance solid state lighting fixtures throughout the United States that are not yet covered by the ENERGY-STAR standard. In North America, luminaries sold with DLC registration are eligible for North American government subsidies.
