Direct answer: Most LED rebate claims fail on paperwork, not on equipment. A complete claim file needs nine documents: written pre-approval where the program requires it, a baseline fixture inventory, before and after photos, an itemized invoice that lists model numbers and quantities, dated proof that every installed model was on the DLC Qualified Products List, manufacturer spec sheets, controls documentation, disposal records where required, and correct payment paperwork. Build the file before the purchase order is cut, because several of these documents cannot be recreated after the old fixtures leave the site.
What the utility actually verifies before it pays
Rebate programs pay for verified energy savings, so the reviewer checks three things: were the products eligible on the day they were installed, were they installed in the quantities and locations invoiced, and is the baseline honest. Every document in the claim file exists to answer one of those three questions. Miss any of them and the entire claim stalls, even when the fixtures themselves are beyond reproach.
Product eligibility runs through the DesignLights Consortium Qualified Products List. The QPL is the screening mechanism for roughly three-quarters of North American commercial lighting incentive programs, and many programs pay a larger incentive for DLC Premium tier products. The detail that trips experienced project teams: eligibility is judged on the installation date, not the design date. Listings are versioned, tiers change, and products get delisted. A fixture listed under the retired SSL V5.1 requirements must have been updated to stay listed, with V5.1 products removed from the QPL as of December 15, 2026 under the current transition schedule. A screenshot from last year proves nothing about today.
The nine-document claim file
Programs differ in forms and portals, but the underlying evidence list is remarkably consistent. Treat the following table as the master checklist for a commercial lighting rebate file.
| Document | What it must show | Where claims fail |
|---|---|---|
| Pre-approval or reservation letter | Written approval issued before installation, where the program requires it | Custom-track projects installed before approval are usually denied outright |
| Baseline fixture inventory | Existing fixture types, model numbers, wattages, quantities, locations, hours of use | “We had old LEDs” is not a baseline; missing wattages trigger conservative assumptions |
| Before photos | Energized existing fixtures, wide shots plus close-ups, dated | No baseline photos means the utility may pick a lower-wattage assumption and cut the rebate |
| Itemized invoice | Contractor and customer details, unique invoice number, date, quantity per model number, cost breakdown | Aggregated line items such as “LED high bays, qty 80” cannot be matched to listings |
| DLC QPL proof | QPL page for each exact model, with tier and a capture date on or near the installation date | Proof pulled after delisting, or for a different product variant |
| Manufacturer spec sheets | Cut sheet for each installed model, showing input wattage that matches the invoice | Spec sheet wattage differs from invoice wattage |
| Controls documentation | Model and quantity of sensors or networked controls claiming the adder, plus configuration evidence | Controls listed on the invoice but never documented as commissioned |
| Disposal records | Recycler receipt for removed lamps and ballasts, where the program requires it | Skip it and the savings calculation loses its disposal line, or the claim delays |
| Payment paperwork | Completed W-9 for the payee, payment assignment form if the payee is not the utility customer | Rebate assigned to a contractor with no W-9 on file |
Invoice wording that survives an audit
The invoice is the document reviewers lean on hardest, and the one most often written wrong. Utility program manuals are explicit about the required level of detail: the contractor company name and address, the customer name and site address, a unique invoice number, the invoice date, the quantity of each item by model number, and the total project cost broken out across equipment, labor, permitting, disposal fees, equipment rental, design or commissioning, and sales tax.
The model number printed on the invoice must match the model number on the QPL listing exactly. Distributor part numbers, abbreviated SKUs, and family-level descriptions are the most common reason an otherwise eligible project gets bounced back. Before the invoice is issued, send the distributor the exact qualified model strings and ask for them to be entered verbatim. It takes one email.
DLC proof: list it, tier it, date it
Save the QPL listing page for every model in the project, showing the manufacturer, the qualified model number, the DLC Product ID, the tier, and the listing date. Capture it at specification time, then re-verify before ordering and again on the installation date, because listings can lapse or change tier between those points. If you are choosing between two similar fixtures, the tier decision belongs in the specification stage: Premium listings typically unlock a meaningfully larger incentive, and the premium often outweighs the price difference between the two units. We cover that trade-off in DLC Standard vs DLC Premium, and the path a fixture takes onto the list in the DLC V6 listing process.
A minority of product categories are screened through ENERGY STAR instead, most commonly screw-base lamps and some residential-type downlights. Check which list your program references per category.
Pre-approval: prescriptive vs custom tracks
Prescriptive programs pay a fixed amount per qualifying fixture and are comparatively forgiving on sequence, though many still recommend or encourage pre-approval and some reserve nothing until the pre-approval letter is issued. Custom programs pay on calculated or measured savings and almost always require written pre-approval before any equipment is purchased or installed. Installing first and applying after is the single most common, and most fatal, sequencing error: on custom projects the utility wants to see the space as it was.
| Aspect | Prescriptive track | Custom track |
|---|---|---|
| Pre-approval | Often optional, but recommended; some programs require it for larger projects | Effectively mandatory before purchase or installation |
| Incentive basis | Fixed amount per fixture or per lamp from the published table | Calculated from project-specific kWh savings, verified after installation |
| Typical review time | Commonly a few weeks for pre-approval and 4 to 8 weeks for payment after final review | Commonly 8 to 16 weeks or longer with measurement and verification |
| Extra documentation | Invoice, QPL proof, spec sheets, photos | All of the prescriptive set plus savings calculations, baseline audit data, and often post-installation measurements |
| Deadline discipline | Program-specific; one Pennsylvania utility program, for example, requires the final application within 180 days of project completion | Pre-approval date defines the eligibility line; work before it is typically ineligible |
Baseline evidence and photo discipline
The baseline is the number the incentive is calculated from, so utilities defend it aggressively. Document the existing fixtures before anything is removed: fixture type, model numbers where readable, input wattage, quantity per area, and the operating schedule. Twelve months of utility bills, the account number, and the service address usually accompany the application.
Photograph the old installations energized, in wide shots and close-ups, from consistent positions, then repeat the same angles after installation. If a claim is audited and the baseline cannot be established, programs typically default to a conservative assumption, often the lowest plausible fixture wattage, which quietly reduces the rebate. In some cases the claim is denied entirely. Photos are the cheapest insurance in this entire process.
The silent claim-killers: substitutions and wattage settings
Mid-project substitutions sink claims that were otherwise perfect. Most programs require that any product substitution be approved before installation, and the substitute must carry its own valid listing and meet or exceed the efficiency of the approved product. If the crew opens a different carton than the one on the approval letter, stop and notify the program administrator first.
Selectable-wattage fixtures create a second trap. Several programs calculate the incentive at the field-set reduced wattage rather than the nameplate maximum, and that setting must be verifiable, through photo documentation of the switch position, a screenshot of the driver configuration, or an on-site check. If the program cannot verify the reduced setting, expect the incentive to be calculated at full input wattage. Record the settings during commissioning, while the lift is still on site. Finally, do not mix rebate-eligible and non-eligible fixtures in a single application; separating the inventory by eligibility keeps one questionable model from holding up the whole project.
After submission: timelines, audits, and retention
Prescriptive claims commonly pay within 4 to 8 weeks of final review, custom claims within 8 to 16 weeks or longer when measurement and verification apply, and many programs quote 60 to 90 days from claim approval to payment. Program budgets are annual and first-come, and funds can be exhausted mid-year, so submit early in the program year.
Payment is not the end of the file. Utility programs commonly reserve the right to audit claims for up to three years after payment, and prudent facility teams keep the complete project file for at least four years, longer when federal energy incentives are involved alongside the utility rebate. Store copies in two places.
Frequently asked questions
Do I need pre-approval for a small prescriptive retrofit?
Often not, but check the program manual rather than assuming. Many prescriptive programs accept post-installation applications, sometimes with a strict deadline measured from project completion. Custom programs and larger prescriptive projects usually require pre-approval, and custom work installed before approval is typically ineligible.
What if my fixture is not on the DLC QPL?
Then most prescriptive programs will not pay for it, regardless of how the fixture performs. A few programs offer an ad-hoc review path using LM-79 test data and other documentation, but approval is discretionary and slow. Verify QPL status for the exact model at specification time, before bidding, not after the fixtures arrive.
How long should I keep rebate documentation?
Plan on a minimum of four years, because claims can commonly be audited for up to three years after payment. Keep records longer, typically five or more years, when the project also involved federal energy incentives, and store the file in two locations.
Who should receive the rebate, the owner or the contractor?
Either can, depending on who holds the utility account and how the deal is structured. If the payee is not the utility customer, programs typically require a completed payment assignment form and a current W-9 from the payee. Sort this out before submission, not after the check is cut to the wrong entity.
Why was my claim rejected when the fixtures clearly qualified?
In almost every case the cause is a documentation defect: invoice line items that do not name qualified model numbers, QPL proof pulled for the wrong variant or after a tier change, missing baseline photos, or an unverifiable wattage setting on a selectable fixture. The equipment was fine; the file did not prove it.
