DLC V6.0 lighting rebates depend on both product qualification and utility transition rules. The DesignLights Consortium (DLC) will delist products that have not completed its Solid-State Lighting (SSL) V6.0 update from the active Qualified Products List (QPL) on December 15, 2026. Commercial LED rebates in 2027 may still accept older qualifications under program-specific exceptions, making equipment selection and project timing critical.

Key Takeaways

The transition creates several checkpoints for commercial lighting projects.

How can businesses reduce rebate eligibility risks?

• Verify the exact model’s qualification version and controls classification.
• Confirm utility transition rules before committing to equipment.
• Avoid relying on pending manufacturer applications as proof of qualification.
• Preserve dated product records throughout the project.
• Reassess estimated incentives when equipment or schedules change.

What Is Changing Under DLC V6.0?

DLC V6.0 raises minimum efficacy requirements, measured in lumens per watt (lm/W). The DesignLights Consortium’s published transition guidance identifies weighted-average increases of 14% for Standard products and 12% for Premium products. Actual thresholds vary by product category and applicable allowances.

Light-quality updates include revised correlated color temperature (CCT) criteria, lower maximum CCT limits for outdoor product types, and expanded reporting for adjustable products.

DLC Premium requires integral controls or qualifying controls-ready capability, with products falling within Controls Categories 1–6. Category 0 products without integral control capabilities cannot qualify as Premium. Networked lighting controls (NLC) are one pathway; an installed networked system is not universally mandatory. Premium also requires continuous dimming to 10% of maximum output or lower.

For outdoor projects, Light Usage for Night Applications (LUNA) V2.0 adds light-pollution criteria while retaining SSL efficiency requirements and applicable allowances. These include shielding-option requirements for specified area, roadway, and decorative products; category-specific uplight limits using Backlight, Uplight, and Glare (BUG) ratings; and nominal CCT limits of 3000 K for luminaires and 2700 K for lamps and retrofit kits. Not every LUNA product must have zero uplight.

What Does the DLC Delisting Deadline of December 15, 2026 Mean?

The October 9, 2026 manufacturer update application deadline has passed. According to the DesignLights Consortium’s Transition to SSL V6.0 and LUNA V2.0 Requirements guidance and official FAQ updates, products that have not completed qualification will be delisted on December 15, 2026.

The active QPL has no automatic grandfathering. Products awaiting review may be temporarily delisted and relisted following approval. Any continued rebate eligibility depends on the incentive program’s rules.

Is There a DLC Qualified Products List Grace Period for Rebates?

A rebate grace period is program-specific, rather than a universal extension of active QPL status.

Wisconsin’s Focus on Energy provides an example. Its published Updated Lighting Requirement requires SSL V6.0 beginning January 1, 2027, for products needing DLC qualification, with these exceptions:

These provisions apply to eligible customers of participating Wisconsin utilities. Focus on Energy also notes that older-qualified products may qualify for general wattage reduction rebates. Confirm requirements separately for every project territory.

How Should Businesses Document DLC V6.0 Lighting Rebate Eligibility?

Create an eligibility file before finalizing the incentive estimate:

1. Match the manufacturer, complete model number, and product identifier to the QPL entry.
2. Save timestamped PDF exports or screenshots at specification, purchase order issuance, and installation closeout. Capture qualification version, listing status, and controls details to support audit review.
3. Obtain written confirmation of the governing qualification date, grace-period conditions, and whether existing preapproval remains valid.
4. Retain invoices, installation records, and correspondence; recheck substitutions and schedule changes.

Historical screenshots document what was listed at the time of review. They do not override program rules or guarantee payment.

Frequently Asked Questions

Are custom lighting rebates affected by DLC delisting?

They can be. Custom incentives calculated from verified kilowatt-hour (kWh) reductions may still require product qualification. Unlike prescriptive rebates with predefined measures and rates, custom projects require individual savings review. Do not assume that calculated savings bypass DLC rules; confirm equipment acceptance with the administrator.

Will delisted product records disappear?

No. The DLC retains historical records under the QPL’s “Delisted” filter, allowing users to review prior qualification.

Do private-label fixtures require separate verification?

Yes. Original equipment manufacturer qualification must precede private-label applications. Verify the branded model being purchased rather than assuming another brand’s listing covers it.
