DLC Releases New Logos For Each QPL Impacting Product Marketing Materials

The DesignLights Consortium (DLC) has released four new logos, allowing manufacturers and distributors to indicate which products are listed on each of the four DLC Qualified Product Lists (QPLs). The four updated logos are designed for use with products approved for the DLC’s Solid-State Lighting (SSL) and Networked Lighting Controls (NLC), Horticultural Lighting, and LUNA qualified products lists (QPL). Effective April 21, 2022, these logos are valid to indicate qualification on the DLC QPLs.

The DLC encourages all manufacturers with listed products to update their marketing materials with the new logos, which can be found on the DLC Marketing Toolkit webpage. For proper use of the logos, refer to the Logo Use Quick Guide and the full Logo and Trademark Use Guidelines.

The DLC does not expect manufacturers to immediately update older materials but encourages updating as soon as is feasible. For the time being, old QPL logos are still valid to identify DLC qualified products, and QPL users should note that they may still see the old logos used to indicate qualification. The DLC recommends that users looking for qualified products always verify the listing on the individual QPLs. If you have questions about the new logos or updating your marketing materials, contact DLC at
