DLC’s SSL V6.0 list is the date that rebate paperwork will follow

The DesignLights Consortium published the final SSL V6.0 and LUNA V2.0 technical requirements on November 3, 2025. It is the first major rewrite of the DLC solid-state lighting requirements in more than five years. For anyone who lives in rebate forms, the qualified products list is the practical version of those rules.

DLC said applications under the new requirements would open on January 5, and that the requirements take effect in January. Products already on the list are not dropped that day. DLC said previously qualified products stay on the SSL and LUNA qualified products lists until December 2026. There is a window when both generations sit on the list, and a date after which the older listings come off.

On efficacy, DLC stated that the new requirements raise the average threshold across qualified product types by 14 percent. Some product types move by as much as 19 percent. Those figures come from DLC’s own release. They are not a count we ran against the list. The release also ties the Premium classification to higher efficacy and tighter controllability rules, which is the part rebate programs tend to copy when they update their forms.

LUNA V2.0 travels with the same release. LUNA is DLC’s outdoor program aimed at limiting light pollution. A parking-lot or wall-pack submittal that was qualified under the previous LUNA version should be checked against the December 2026 removal date before it is promised on a job that will still be open then.

None of this changes a UL listing, and it does not rewrite the NEC. It changes which catalog numbers a utility or a specification will still accept when the paperwork asks for a current DLC listing. Pull the listing ID on the submittal, not the one printed on last year’s cut sheet.

This sample paraphrases the DesignLights Consortium release of November 3, 2025. It does not rank products, and it does not say which Integrity LED fixtures are on the list.
