DLC Certification

As an accredited testing laboratory, we’ve helped thousands of manufacturers complete testing for their products and achieve DLC certification.

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.

2. More about DLC certification

The DesignLights Consortium (DLC) 5.1 is an updated version of the DLC technical requirements and quality standards for commercial lighting products, specifically focusing on LED fixtures and bulbs. DLC 5.1 sets more stringent criteria for energy efficiency, performance, and quality compared to previous versions, encouraging the adoption of even more advanced and efficient lighting technologies.

4. Differences between DLC certification and Energy Star® certification

Both DLC certification and Energy Star® Certification play a crucial role in promoting energy efficiency and sustainability, offering consumers and businesses options to choose environmentally friendly lighting solutions tailored to their needs, but they have some key differences:

  • Scope: Energy Star® Certification covers a wide range of products, including appliances, electronics, and lighting, while DLC certification specifically focuses on commercial lighting products such as LED fixtures and bulbs.
  • Certification Criteria: Energy Star® Certification sets energy efficiency guidelines for products based on national standards, while DLC certification establishes technical requirements tailored to commercial lighting applications.
  • Incentives: Products with Energy Star® Certification may qualify for rebates and incentives from utility companies and government programs, while DLC-certified products are often eligible for utility rebates specifically targeting energy-efficient lighting upgrades.
  • Recognition: The Energy Star® label is more widely recognized by consumers across various product categories, while DLC certification is more industry-specific and targeted towards commercial lighting professionals.
