DLC certification stands for DesignLights Consortium certification. It’s a third-party certification program aimed at promoting energy-efficient lighting products, primarily in the realm of LED lighting. Products that receive DLC certification meet certain standards for energy efficiency, quality, and performance. This certification is often sought after by manufacturers to demonstrate the credibility and efficiency of their lighting products to consumers, businesses, and regulatory bodies. DLC certification can be especially important for businesses looking to qualify for energy efficiency incentives or rebates.

The DesignLights Consortium (DLC) certification is a significant mark of approval within the lighting industry, especially for energy-efficient lighting solutions. Here’s a detailed introduction to DLC certification:

What is DLC?

  1. Purpose: DLC is a non-profit organization dedicated to advancing energy-efficient lighting technology. It was formed to promote the adoption of high-performing, energy-efficient lighting solutions.
  2. Membership: DLC consists of utilities, energy efficiency organizations, manufacturers, and lighting designers. It collaborates with various stakeholders to develop and maintain specifications for energy-efficient lighting products.

DLC Certification

  1. Product Eligibility: DLC certification applies primarily to LED lighting products, including fixtures, lamps, and retrofit kits. These products must meet specific criteria outlined by DLC to qualify for certification.
  2. Criteria: DLC establishes rigorous performance and quality standards for lighting products. These criteria typically include energy efficiency, light output, color quality, and product longevity. Products are tested and evaluated against these standards to determine eligibility for certification.
  3. Benefits:
    • Energy Efficiency: DLC-certified products are designed to consume less energy than traditional lighting solutions, resulting in lower electricity bills and reduced environmental impact.
    • Quality Assurance: DLC certification ensures that products meet high standards of performance and reliability, providing confidence to consumers and businesses.
    • Incentives and Rebates: Many utility companies offer incentives or rebates for the purchase of DLC-certified products, making them more financially attractive to consumers and businesses.
    • Market Access: DLC certification can open doors to new markets and opportunities, as many government agencies, businesses, and organizations prioritize energy-efficient lighting solutions.
  4. Types of Certification:
    • Standard DLC: Products that meet the standard DLC specifications for energy efficiency and performance.
    • Networked Lighting Controls (NLC): DLC also offers certification for networked lighting control systems, which allow for advanced lighting management and energy savings through automation and optimization.

Application Process

  1. Submission: Manufacturers submit their products for DLC certification, providing detailed information about product specifications, performance data, and testing results.
  2. Evaluation: DLC conducts thorough evaluations of submitted products to ensure they meet the specified criteria. This may involve laboratory testing, review of technical documentation, and verification of product performance.
  3. Certification: Products that successfully meet DLC’s requirements are awarded certification. They are listed on the DLC Qualified Products List (QPL), which serves as a resource for consumers, businesses, and utilities seeking energy-efficient lighting solutions.


DLC certification plays a crucial role in promoting energy efficiency and quality in the lighting industry. It provides assurance to consumers and businesses that certified products meet stringent performance standards, while also facilitating access to incentives and rebates. As the demand for energy-efficient lighting continues to grow, DLC certification remains a valuable endorsement for manufacturers and a trusted resource for those seeking reliable lighting solutions.
