Eight years ago, I approved my first commercial lighting order. I was proud. I was also wrong.
Today I help distributors, contractors, and facility teams make the same decision I've messed up more times than I like to admit. I've personally made and documented 14 significant mistakes, totaling roughly $96,000 in wasted budget. This article is the checklist I wish I'd had back then.
Let's put a spotlight on a question that keeps coming up: OEM vs. private label in commercial lighting.
OEM vs. Private Label: The Framework
OEM means the lighting manufacturer designs, tests, and stands behind the product. Private label means you take an existing fixture, often from a contract factory, and put your brand on it. Both models can work. They're not equally safe.
I'll compare them on four dimensions: compliance, pricing transparency, lead time, and liability. And I'm not neutral. I've been burned by hidden costs, so I'd rather give you a clear opinion than a vague it depends.
Dimension 1: Compliance and Specifications
Many buyers focus on lumens, wattage, and CRI. They completely miss the paperwork. In commercial lighting, the paperwork is the product.
An OEM fixture—like a Kenall ceiling light specified for a hospital corridor—comes with a defined photometric file, construction details, and a certification record that can be traced to the design. A private-label fixture may contain similar components, but its documentation is only as strong as the importer or distributor standing behind it.
Here's something vendors won't tell you: UL Listed on a private-label product doesn't always mean the listing covers every variation you're buying. I once ordered 320 exit signs with a custom stencil. The stencil wasn't in the UL file. The authority having jurisdiction caught it before installation, which saved us from a failed inspection, but only after a three-week delay.
According to UL Solutions (ul.com), a UL mark indicates a product has been evaluated to applicable safety standards. But a mark is only meaningful if it covers the exact model and options you're buying. Verify it at productiq.ul.com. The DesignLights Consortium (designlights.org) is similarly strict: DLC qualification must cover the exact product family to qualify for rebates.
If you're an exit sign distributor, this is the difference between a smooth fire marshal inspection and an awkward phone call. My conclusion: for life-safety and spec-grade products, OEM wins this dimension. Period.
Dimension 2: Pricing Transparency
Now let's talk money. This is where I've made my most expensive mistakes.
Private label quotes often start with a tempting low unit price. Then come the extras: custom label artwork, packaging changes, compliance documentation, pallet configuration, sample approval, and sometimes a visit fee if you want to audit the factory. I've learned to ask what's NOT included before what's the price.
On a recent 6-SKU order for a warehouse lighting manufacturer, the private-label quote was 28% lower per fixture. After all the hidden costs, the total project cost came out 4% higher than the OEM alternative. That's my own line-item comparison from Q1 2024, and it's not an unusual result.
The transparent quote usually looks more expensive. It lists every fee on page one. It doesn't need a surprise line item at the end. The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end.
Bottom line: private label can work if you're disciplined enough to model every cost. But the OEM pricing model is designed to be transparent, and in my experience, transparent pricing wins. If you can't calculate the total cost of ownership, choose the quote you can verify. That's the spotlight on pricing: the lowest line item is not the lowest total cost.
Dimension 3: Lead Time and Customization
Here's the dimension that surprised me.
Private label is faster only if you're buying an existing SKU with zero changes. The moment you need a custom sticker, a different driver, or a lens option, you're in a queue behind the factory's own brand customers. You're not the customer; you're a side project. What most people don't realize is that standard turnaround in private label often includes buffer time to allow the factory to batch your order with other work.
OEM manufacturers, by contrast, have their engineers and production team in the same building—or at least on the same continent. If you need a modification to a Kenall commercial lighting product, the change order goes to someone who can actually answer the question. A specification mistake can be caught before the fixture goes into production, not after.
Sure, a truly custom OEM build can take longer. But the quote tells you that from the start. I'll take an honest 10-week lead time over a promised 6-week lead time that slips to 11 weeks without a phone call.
That's why the conventional advice to pick private label for speed is reversed. For standard SKUs, private label can be great. For anything custom, OEM wins.
Dimension 4: Warranty and Liability
I didn't fully understand warranty liability until a $3,200 order of exit signs came back with driver failures in year two.
The customer didn't care which factory made the board. They called me. I called the importer. The importer called the factory, which blamed the driver supplier. Meanwhile, my customer's building was out of code compliance. That's the private-label risk: you own the customer experience, even when you don't own the manufacturing.
With an OEM, liability sits with the manufacturer. If a known component issue appears, the manufacturer issues a field notice and coordinates the fix. You're not translating claims between a customer and a factory six time zones away. The third time I dealt with a warranty dispute, I finally created a vendor risk checklist. Should have done it after the first time.
This matters even more for emergency lighting and exit signs. These aren't decorative fixtures. They're safety devices. If a private-label product fails in a crisis, nobody will care about the price per unit.
My conclusion: choose private label only if you're prepared to own every failure. For critical environments, that's a heavy burden. OEM wins on liability, clearly.
What about Kenall?
I've been using Kenall as an example because, in our sourcing, Kenall commercial lighting products have a published engineering record and a team that answers technical questions. That's not the same as saying every Kenall product automatically meets every requirement—no manufacturer can claim that. You still verify specifications against the project and the listing.
But if a project demands a Kenall ceiling light, that's an OEM product with known characteristics. A private-label equivalent is not the same product, no matter how similar it looks in a photo.
Which Should You Choose?
Here's my practical, scenario-based advice.
- Choose OEM when the project involves life safety, healthcare, critical environments, or specifier-driven design. Also choose OEM if you don't have an in-house engineer who can review private-label documentation.
- Choose private label when you're buying simple, non-critical products in high volume, and you have an audited factory relationship, a warranty plan, and a realistic total-cost model that includes hidden fees.
- Do not choose private label solely because the line item price is lower. That's how I lost $96,000 over several years.
Final Thought
It took me four years and roughly 300 orders to understand that vendor relationships matter more than vendor capabilities. I do not mean occasionally—I mean consistently. The best OEM is not the one with the shiniest catalog; it's the one that tells you what's included. The best private-label factory is not the one with the lowest quote; it's the one that gives you the same quote twice.
Compare the certification paperwork. Compare the hidden costs. Compare what happens when a fixture fails. Then make your decision. That's a comparison worth making. Prices and regulations change, so always verify current listings and codes at the official sources before you spec.
