Flood Light Distributor Buying Guide: 7 Private Label Checks Before You Order

I’ve worked on private label and OEM flood light orders for about ten years—first as a product manager on the distributor side, and now at Greenshine Lighting, where I review OEM and wholesale requests from lighting distributors. I made expensive mistakes when I was the buyer, and I kept records of them. This flood light distributor buying guide is built from those records and from the checklist we now use on private label projects.

The worst mistake happened in 2019. I approved a 100W flood light sample because it looked impressive in a warehouse. I didn’t compare the photometric data with the beam angle our customers actually needed. We put our own brand on 1,050 pieces, sold them, and then spent months handling complaints that the beam was too narrow. Rework and returns cost roughly $11,000 and added three weeks to the next delivery. That mistake earned its place at the top of our team checklist.

There are 7 checks on that checklist. I’ll walk you through each one. They’re not difficult, but they need to be done before the order, not discovered after it.

Five checks to make before you sign

These first five checks make sure the product you quote is the product you need. They also make supplier comparison faster, because every supplier should be quoting against the same specification.

Step 1: Put your destination spec in writing before asking for a price

Don’t send a supplier a one-line request like “quote for 100W LED flood light”. That sounds efficient, but it isn’t. That line doesn’t tell them the input voltage, color temperature, certification, beam shape, dimming or warranty you need.

I receive quote requests like that at Greenshine, and I can’t answer them responsibly. A flood light for a US commercial parking lot—120–277V, UL listed, 4000K—and one for a European facade project—220–240V, CE, 3000K—are different products even at the same wattage.

Write down these details before contacting suppliers: voltage range, CCT and CRI, certification marks for your target market, IP and IK rating, beam distribution, dimming protocol and warranty years. Note whether you need 0–10V dimming or a photocell. Then ask every supplier to quote against that spec.

A clear spec doesn’t make you difficult. It makes you efficient. It removes the back-and-forth and lets you compare apples to apples.

Step 2: Get photometric data, then actually read it

This is the check that would have saved my 2019 project. Looking back, I should have spent twenty minutes opening the .ies file. At the time I treated photometric data as a supplier-level detail. For flood lights, it is the product spec.

Ask the supplier for the .ies or .ldt file and the photometric test report for the actual fixture. Then look at the beam angle and distribution. A 100W fixture with a narrow symmetric beam and a 100W fixture with an asymmetric parking lot distribution will perform completely differently in the field, even if the color of the light looks identical.

Also check what the lumen number means. A headline like 12,000 lm can be chip lumens calculated at 25°C, before the light passes through the optics and before the driver heats up. The fixture itself may deliver only 10,500 lm once installed. I don’t have hard data on how widespread optimistic spec sheets are. What I can say from sample comparisons I’ve reviewed over the past three years is that gaps between quoted and measured output of 5–15% are not rare.

If you’re buying solar flood lights, ask for the output curve over 8–10 hours, not just the peak in the first hour. A solar flood light can look bright on a workbench and drop to a fraction of that by 2 a.m. That behavior only shows up on a discharge curve.

Step 3: Verify the driver and surge protection

The driver is the component most likely to fail first in an outdoor LED flood light. I wish I had tracked component-level failures more carefully when I was a distributor. Anecdotally, 11 of my first 14 warranty returns in one season were electronics problems—drivers, connectors and surge damage.

When you compare quotations, ask for the driver brand and model and put it in the order. Also clarify driver efficiency, power factor, dimming option, ambient temperature rating and warranty. If a fixture will be sold with a 5-year warranty, I want a driver that has a documented lifetime at the operating temperature of that fixture.

Outdoor flood lights get hit by grid surges. Ask for the surge immunity test report referenced to IEC 61000-4-5 at 4 kV or 6 kV. This is one of the easiest checks to ignore in a sample review and one of the most common causes of field failures once a line of lights is installed in exposed locations.

Step 4: Open the sample, weigh it and inspect the mechanical details

Once a sample arrives, don’t evaluate it only by looking at the housing from the front. Weigh it. Mechanical weight isn’t everything, but if two fixtures with the same wattage and driver look similar and one is much lighter, ask where the heat goes. An LED module and driver last longer when the housing is designed to move heat away from them.

Look at the lens material, gasket, cable gland, mounting bracket and drain holes. Ask for the IP and IK test reports instead of accepting them as printed specs. And if you have a watt meter, measure the actual power draw and power factor of the sample. If measured power is 15% below label, the light output will follow.

Step 5: Write down every private label detail, especially the boring ones

Most private label flood light projects I see start with a logo file and end with a purchase order. The logo is the visible part, but the private label scope also includes rating label, model number, legal company name, packaging, barcode, manual and warranty documents. Every one of those can stop a delivery.

I’ve watched projects stall because nobody specified how the logo should be applied—die-cast, silk-screened or sticker—or which black was the right black. Those choices change cost, tooling and lead time. If you don’t write them down, the factory will use the default option, which may not match your brand.

Before ordering, confirm on paper: logo application and location, housing color with a color code, manufacturer and importer names on the rating label, model number printed on the product, packaging type and dimensions, manual language, barcode owner and registration. Add country-specific label requirements if your market demands them.

This may feel like too much detail for someone buying 100 fixtures for one job. For a distributor building an SKU that will be reordered, this step prevents the same error from repeating twelve times a year.

Two checks to make right before production

The next two checks happen after you’ve chosen the supplier and approved the sample, but before mass production starts.

Step 6: Check certifications by model number, not by supplier name

A lot of distributors ask “do you have UL and CE” and accept the answer as yes. That doesn’t verify that the exact model you’re importing, with your model number and your label, is the model covered.

Ask for a searchable listing or directory entry that shows the manufacturer, model, standard and current status. Compare it with the model number that will appear on your product label. If you plan to assign your own model numbers, verify that those model numbers are already in the certification file or can be added under the supplier’s private label procedure. In the EU, make sure the Declaration of Conformity names the actual model and the responsible importer or manufacturer.

If the product is a solar flood light, don’t stop at the LED fixture certificate. Battery and solar panel compliance also matter in most regulated markets. A complete file covers the energy storage and charging parts, not just the luminaire.

Step 7: Ask for a pre-production sample from the actual production line

The golden sample that got you to this point was probably built by an engineer taking extra care. That’s not the same as a unit pulled from the production line after tooling, painting, logo application and packaging are set up.

For a private label product, the pre-production sample is where you catch the real mistakes: wrong logo color, wrong model label, typo on the carton, manual in the wrong language, barcode that doesn’t scan. Ask for one sample from the actual line, or at minimum a photo and video of that exact unit showing the label, logo and packaging together.

This step adds a few days to the schedule. Build it into your timeline. It’s much easier to fix one pre-production unit than 500 housings that are already painted and printed.

The quick version, plus one honest warning

If you only remember four things from this flood light distributor buying guide, remember these:

1. Wattage does not define a flood light. Your destination spec does.
2. No photometric file, no driver confirmation and no surge test report means the product isn’t fully specified yet.
3. Private label includes the label, packaging, manual, model number and certification file—not only the logo.
4. Certification is model-level and must match the product you actually ship.

None of these checks will protect you from every production issue. A bad batch can still happen, and no importer can eliminate all risk. What this checklist does is remove the mistakes that are made before production starts, when the cost is still low and the fix is still easy.

Looking back at my 2019 flood light mistake, the cause wasn’t a bad factory. It was a buyer who approved a sample without reading the photometric data. Run this checklist before you sign the order and you’ll avoid that version of yourself.
