1. DLC certification
The DesignLights Consortium (DLC) was established in 2009 as a collaboration between utility companies and regional energy efficiency organizations in the United States and Canada. The DLC aims to promote energy efficiency in commercial lighting through the development of technical specifications and quality standards for lighting products. By certifying products that meet these standards, the DLC helps businesses and consumers identify energy-efficient lighting solutions that can reduce energy consumption and operating costs. The DLC certification has become a widely recognized mark of quality and energy efficiency in the lighting industry, driving the adoption of sustainable lighting technologies.
