Solid-State Lighting Technical Requirements

  • SSL V6.0 & LUNA V2.0 Technical Requirements

    The DLC Technical Requirements for LED Lighting: SSL Version 6.0 and LUNA V2.0 introduces a combined set of technical requirements and policies, streamlining what were previously multiple separate policy documents and marks an important milestone in advancing high-performing, energy efficient, and quality lighting for both indoor and outdoor non-residential applications.

    It includes several key updates:

    • A major revision to the DLC Premium classification, expanding beyond efficacy and quality to further enable incentives for advanced controls and integrated lighting systems
    • Clear criteria and improved documentation for manufacturers and specifiers
    • Alignment with technology advances in efficacy, quality of light, and system flexibility.
  • SSL V5.1 Technical Requirements

    Effective on July 1, 2020, Solid-State Lighting Technical Requirements V5.1 begins to build a foundation for quality of light requirements, including spectral quality and glare requirements, and additional controllability requirements.

  • V5.1 Product Eligibility/Primary Use Designations

    The DLC qualifies commercial LED luminaires, retrofit kits, linear replacement lamps, mogul (E39/E40) screw-base replacements for HID lamps, and four pin-base replacement lamps for CFLs on the DLC QPL. Click below to see whether the DLC qualifies your specific product type.

  • V5.1 DLC Premium Requirements

    DLC Premium is a higher-performance classification for luminaires and retrofit kits. Products submitted to the DLC Premium classification must meet higher efficacy and lumen maintenance requirements and must also provide a driver ISTMT and information about integral controls.

    SSL V6.0 and LUNA V2.0 Premium requirements can be found within the Part III and Part IV of the Technical requirements for LED Lighting: V6.0 and LUNA V2.0

  • Testing Lab Requirements

    DLC applications require that product testing be conducted at an accredited laboratory appropriate for the performance being evaluated. These tests may include in situ measurement tests (ISTMT), LM-79, LM-80, LM-84, or compatibility tests for four pin-base replacement lamps for CFLs.

  • Past Technical Requirements

    Development of Technical Requirements for the DLC Solid-State Lighting QPL is an ongoing process involving input from Members, stakeholders, and our Technical Committee. See below for an archive of past versions of the DLC Solid-State Lighting Technical Requirements.
