Who This Checklist Is For
If you're specifying, ordering, or receiving Lithonia Lighting products—especially security lights, surface mount kits, or components like chandelier motors—this is for you. It's for the person who doesn't want to be the reason a $22,000 redo happens.
I review roughly 200 lighting items annually for a mid-sized commercial contractor. This checklist is what I run through every time. If you're doing a one-off residential job or working with luxury spec, your experience might differ. But for the standard commercial runs I see—this covers the gaps.
Here are the 5 steps I use.
Step 1: Verify the Product Matches the Spec Sheet—Not Just the Box Label
This sounds obvious. It's not.
In Q1 2024, we received a batch of 48 Lithonia Lighting security lights. The box said 'LBL' series. The label on the box said the same. But the fixture inside had a different driver model than what was specified in our contract. The driver was a lower wattage rating. Would it work? Probably. Would it fail faster under continuous outdoor use? Yes.
What I do: I open one unit from each pallet layer. I check the model number, driver part number, and CCT rating against the approved submittal—not just the box. I take a photo and log it.
Why this matters: Substitutions happen. Sometimes it's a supply chain issue. Sometimes it's 'we ran out of the spec'd driver.' If the contract says 'LBL 4R 40K 120/277,' I want the fixture that matches that. Period.
Checkpoint: Does the internal component label match the approved submittal? If not, flag it.
Step 2: Check the Surface Mount Kit Fitment Before Installation
The Lithonia Lighting surface mount kit is a common accessory. It's used to convert a recessed fixture to a surface mount. Theoretically straightforward. In practice, the wrong kit or a poorly packed kit can delay a job by hours.
I've seen three issues repeatedly:
- Kit-to-fixture compatibility: Not all kits fit all housings from the same manufacturer. The SMK series might not match a specific housing revision.
- Missing hardware: We received a kit once without the mounting screws. It was a $10 fix, but finding the right screws on a Saturday cost us two electricians' overtime.
- Cosmetic defects: Scratches or dents on the trim kit. In a retail lobby, that's a rejection.
What I do: Before the job goes to the field, I do a dry fit test. I mount one kit on the designated housing in the shop. If everything aligns, I release the batch. If not, I document the exact issue and send photos to the supplier.
Checkpoint: Does the surface mount kit physically fit the housing without modification? Is all hardware present?
Step 3: Test the Chandelier Motor for Noise and Vibration (The One Most People Skip)
This is the step that gets ignored. And it's the one that causes the most headaches.
A chandelier motor is a small, often cheap component that drives the rotation of a chandelier or decorative fixture. The spec sheet says it runs at X RPM. It'll turn. But how it turns matters.
I ran a blind test with our installation team: same chandelier model, same motor spec, two different batches. One had a slight vibration at low speed—you could feel it if you touched the chain. The other was smooth. 72% of our installers identified the smooth one as 'more professional' without knowing the difference. The cost difference between the batches was $4 per motor. On a run of 500 units, that's $2,000 for measurably better perception—and fewer callback complaints.
What I do: I power up a sample of chandelier motors before they go to the fixture assembly line. I listen for hum, feel for vibration, and let it run for 10 minutes to check for thermal issues. It's 10 minutes that saves a lot of 'it's making a weird noise' calls later.
Checkpoint: Run a sample motor at low speed. Is it smooth? Quiet? No heat buildup?
Step 4: Confirm the Wiring Configuration for the Light Bar Installation
How to wire up light bar seems like a straightforward search term. It's not a single answer. It depends on the fixture, the driver, the control system, and local code.
What I check specifically:
- Driver input voltage: Is it 120V? 277V? Multi-voltage? I've seen a batch of light bars wired for 277V shipped for a 120V job site. The installer caught it before connecting, but it created a week's delay.
- Dimmability: If the spec calls for 0-10V dimming, does the driver support it? Not all do, even if the fixture is listed as 'dimmable.'
- Grounding: Is the ground wire correctly terminated? In a commercial setting, this is code. In a residential setting, it's often skipped. I don't skip it.
What I do: I pull the wiring diagram from the manufacturer's website. I verify against the actual driver label in the fixture. Then I do a continuity test on a sample unit. It sounds excessive. But I've rejected 12% of first deliveries in 2024 due to wiring mismatches. That's 24 out of 200 items. The cost of testing is nothing compared to the cost of a field rewire.
Checkpoint: Does the wiring diagram match the driver label? Continuity test passed?
Step 5: Document Everything—Especially the Rejections
This isn't a step about checking the product. It's about checking your process. Because if you don't document, you can't prove what you checked.
I keep a log for every batch:
- Date of receipt
- Quantity inspected
- Sample size
- Findings (good and bad)
- Photos of any discrepancy
- Vendor contact and resolution
When I implemented this protocol in 2022, our vendor defect rate dropped by 34%. Not because the vendors got better overnight—but because we could show them exactly what was wrong and why we rejected it.
The most frustrating part? Vendors claiming 'within industry standard' for something clearly off-spec. After the third time, I learned: industry standard and contract spec are not the same thing. The contract wins.
Checkpoint: Is every batch logged with findings? Can you show a pattern over time?
Common Mistakes and What I've Learned
Mistake 1: Assuming 'Same Brand' Means 'Same Fit'
Lithonia Lighting makes hundreds of SKUs. A surface mount kit for the LBL series might not work on the LBU series. I've seen it tried. It doesn't end well.
Mistake 2: Ignoring the Chandelier Motor Until It's Installed
By the time a chandelier motor is mounted and the fixture is hung, replacing it is a full-hour job. Checking it on the bench takes five minutes. Don't skip it.
Mistake 3: Thinking TCO Is Overthinking
The $500 security light that fails after 18 months costs more than the $650 model with a 5-year warranty. I now calculate total cost of ownership before comparing any vendor quotes. It's not always the cheapest option. It's the one that costs less over five years.
Let me rephrase that: the cheapest option is the cheapest. But that doesn't mean it's the most affordable. Not the same thing.
I should add that these are based on my experience with mid-range commercial orders. If you're doing high-spec residential, luxury retail, or a one-off custom piece, your checklist might need different steps. But these five cover the bulk of what I see go wrong. (Should mention: we built in a 3-day buffer for every delivery. Gives us time to check without rushing.)
Start with Step 1. The rest will follow.
