Every supplier shows a good sample. The difference between a partner and a broker appears in the answers to questions about components, certification, tooling ownership and what happens when something goes wrong in container two.
Six questions, and what the answers reveal
Ask these in one email. The speed and specificity of the reply is as informative as its content.
| Question | What you are testing |
|---|---|
| Who holds the safety listing for this model? | Whether they own the certification or borrowed it |
| Which switch and cord set are fitted, and by whom? | Whether they know their own bill of materials |
| Who owns the tooling, and can it be removed? | Whether you can leave without losing the product |
| What is the reorder lead time and minimum? | Whether the second order is easier or harder |
| Which spare parts are available, for how long? | Whether the warranty is cheaper than a replacement |
| Who do you build for in the US today? | Whether they understand the market you are in |
Component-level answers are the tell
A manufacturer names the switch brand, the cord type and the driver supplier. A trading desk describes the lamp. The first can fix a defect at the source; the second has to ask someone else.
Ask for a factory process, not a factory photo
Photographs of a building prove nothing. Ask which processes happen on site — forming, plating, powder coating, assembly, testing — and which are subcontracted, because the subcontracted ones are where quality variance appears.
Test the response to a problem
Raise one small issue during the sample stage, such as a finish variation or a switch feel, and watch how it is handled. The behaviour at that moment is the behaviour you will get when a container is held at port.
Start small, on a real order
A trial order of one or two models, at commercial volumes and through the full process, tests more than a sample programme ever will. Then decide with evidence rather than with a price list.
From evaluation to a standing scorecard
The six questions above qualify a supplier once; what keeps them honest is measurement afterwards. Turn the answers into a simple scorecard — on-time delivery, defect rate at receipt, documentation currency, responsiveness, disclosure of changes — and score it quarterly on evidence rather than impression. The lighting supplier scorecard note gives the six measures, the weighting and the evidence to collect, so the second order is placed on data instead of on the memory of a good sample.

Frequently asked questions
What should I check before choosing a lamp supplier
Verify the supplier can show current safety listings for the exact models, provide reference retailers or contract accounts, and demonstrate consistent quality through inspection records. A factory that treats the listing and the inspection as paperwork rather than process is a risk regardless of price.
How important is the safety listing when evaluating a factory
It is a baseline, not a nice-to-have. For North America the portable lamp should be ETL or UL listed to UL 153, with CSA C22.2 for Canada. If a supplier cannot show the listing for the specific model you will buy, that is a reason to walk away, not to negotiate around.
Should I visit the factory
A visit or a verified third-party audit confirms the capability behind the quotation. For a new supplier or a high-volume program, an audit of production and quality systems is cheaper than discovering a shortfall after a container arrives.
How do you evaluate a lighting supplier before a bulk order?
Ask the six questions above in one email, score the specificity of the replies, then run a small real order through the full process before committing volume. Check that the safety listing covers the exact model rather than the range, that tooling ownership is in writing, and that spare parts and reorder minimums are quoted for the second order rather than the first. Once the relationship is running, keep scoring deliveries and disclosures quarterly so the decision to grow or to split volume stays evidence-based.
