On July 28th, the Design Lights Consortium (DLC) released the second draft of its SSL V6.0 & Luna V2.0 Technical Requirements for LED Lighting. A notable change from the first draft is the removal of some product categories traditionally covered by ENERGY STAR, that were proposed to be added to DLC in Draft 1. These include downlights, downlight retrofit kits, and general purpose, E26, LED lamps, both omnidirectional and directional.
In Draft 2, DLC states, “Based on comments from draft 1, continued discussions with stakeholders and uncertainty regarding the future status of the EnergyStar downlight QPL, requirements for downlights and E26 medium base general-purpose lamps will no longer be included in this revision. We are actively monitoring the situation and may revisit this decision in a future update if needed.”
Other changes from SSL V6.0 Draft 1 to Draft 2 include:
- Omnidirectional and directional medium screw-base (E26) LED replacements for HID lamps (with bare lamp performance and testing criteria) added as product categories
- Omnidirectional and directional mogul screw-base (E39/E40) LED replacements for HID lamps (with bare lamp performance and testing criteria) added
- Modified filtered-Amber LED definition to expand use cases
- Modified Amber LED definitions to address luminaire applicability and address ANSI C78 working 198 group activities
- New technical distinctions for Linear Ambient Strip Luminaire primary use designations (PUD)
SSL V6.0 & Luna V2.0 Draft 2 Technical Requirements are available here.
The DLC will host an informational webinar on Wednesday, August 6, 2025, at 3:00 PM Eastern Time. The webinar will focus on the technical requirements, emphasize the main changes since draft 1, and will include a Q&A session.
