The DesignLights Consortium (DLC) has released for comment the second draft of technical requirements for outdoor LED luminaires that not only save energy and meet the DLC’s Solid-State Lighting (SSL) Technical Requirements, but also include attributes that limit light pollution, sky glow and light trespass.

Drafted with the input of a multi-disciplinary Advisory Group convened last spring, the DLC’s draft LUNA Technical Requirements are meant to mitigate adverse environmental impacts of lighting at night while providing appropriate visibility for people. The DLC is accepting comments on the draft policy through October 22, 2021 ( and anticipates releasing final LUNA technical requirements by December 16, 2021.

Once LUNA is fully implemented in 2022, lighting manufacturers will be able to list and qualify their products to the specification. Project designers will then be able to easily search for LED outdoor lighting products in a subsection of LUNA Qualified Products on the DLC’s SSL Qualified Products List (QPL), which will include luminaires that are both energy efficient and have characteristics enabling best environmental practices for nighttime illumination.
