“DLC available” is not a procurement specification. For rebate-driven projects, the exact ordered model must match a current record on the DesignLights Consortium Qualified Products List, and the local utility still decides whether that product and project qualify for an incentive.
Buyer takeaway: search the full order code before issuing the purchase order. Do not infer qualification from a series name, logo on a brochure or listing for a nearby wattage.
Understand what the QPL does
The DLC QPL is a centralized database of qualified commercial lighting products. DLC guidance notes that the database includes manufacturer, brand, model and family-model information, reported and measured values, warranty data and qualification status. It also states that only model numbers found in the database are considered qualified (DLC manufacturer guidance).
A QPL record can support a utility application, but it is not a blanket rebate approval. Confirm the utility’s program rules, installation date, pre-approval process and required product category.
Build the complete order code first
Ask the supplier to decode every character in the model. Options may represent:
- wattage or field-adjustable output;
- CCT and color options;
- input voltage;
- optic or distribution;
- sensor and control receptacle;
- emergency backup;
- cord, plug and mounting accessory;
- housing finish or private-label brand.
Then search that exact string in the QPL. If the database uses wildcard characters or family notation, obtain written confirmation of how the ordered suffix fits the qualified model construction.
Compare performance fields with the quotation
Do not stop at finding the record. Compare input power, light output, efficacy, CCT, color rendering, distribution, dimming capability and rated life with the quotation and project calculation. A product can be qualified but still be the wrong optical package for the building.
Use model-specific photometric data for UFO high bay layouts and linear high bay aisle layouts. The UFO-versus-linear guide explains why housing shape alone does not determine aisle performance.
| QPL field | Procurement question |
|---|---|
| Model number | Does it match the purchase order exactly? |
| Primary use | Is the product qualified in the relevant high-bay category? |
| Reported wattage/output | Does it match the quoted setting? |
| Controls | Are dimming and sensor options represented correctly? |
| Qualification status | Is the model active on the verification date? |
| Brand/manufacturer | Does it match the product and invoice chain? |
Treat field-adjustable models carefully
Field-adjustable wattage can simplify inventory, but the commissioned setting must still deliver the design illuminance. Document the switch or programming position on the approved submittal and at handover. Prevent unauthorized changes after commissioning.
If optics are field adjustable, confirm which configuration was tested and modeled. Request the IES file for the exact distribution and use the photometric-file validation checklist before accepting a calculation.
Coordinate OEM and private-label listings
A factory’s OEM model and a distributor’s private-label model are different commercial identities. Confirm that the branded order code appears under the correct organization and that the qualification remains connected to the underlying product family.
Require change notification for the driver, LEDs, optics and control options. A commercial promise that a replacement is “equivalent” is not enough when test data or QPL status depends on a defined construction. Apply the controls in the OEM private-label procurement checklist.
Create an audit trail for the rebate file
Before ordering, save:
- the QPL record and lookup date;
- the utility’s current eligibility requirements;
- the exact product quotation and model decoder;
- the approved photometric calculation;
- the product specification and warranty;
- the final invoice and installed-label photographs.
Repeat the lookup before shipment if lead time is long. Programs and qualification status can change. This simple record prevents a rebate dispute from becoming a model-number guessing exercise months after installation.
RFQ wording example
“Supplier shall provide the exact DLC-qualified model number for each ordered configuration and a current QPL record. Quotation, carton, luminaire label, invoice and rebate submittal shall use the same model. State all field-adjustable settings and provide matching photometric files. DLC listing does not by itself guarantee utility incentive eligibility.”
Pair this clause with the industrial lighting RFQ checklist so commercial, photometric and compliance evidence arrive in one controlled submittal.
