How to Source LED Lighting from China Without Surprises

Most problems in a lighting order are decided before production starts. The buyer sends a picture, the factory quotes a price, the sample is approved in a hurry, and the discrepancy only appears when the container is opened. A short, disciplined sequence prevents most of it.

Write the specification down

Start from a document, not a conversation. For each model, record the wattage, colour temperature, CRI, source and delivered lumen, dimensions, finish, diffuser material and the certification required for your market. If two versions of the same housing differ only in diffuser, list them as separate SKUs; buyers and installers will treat them as different products anyway.

Decide early which values are fixed and which are negotiable. Delivered lumen is usually the first casualty when a factory is asked to reduce cost, because a cheaper diffuser absorbs more light. Fix the delivered lumen figure in the purchase order.

Order the sample against the specification

A sample confirms appearance, not compliance. Ask for the sample to be built to the written specification and to include the driver and packaging you expect in bulk. Keep the approved sample, photograph it under neutral light, and label it with the date and the specification revision. That sample is the reference for the inspection.

Decide whether tooling is needed

Existing catalogue models avoid tooling cost and lead time, but they are also available to every other buyer. A new mould gives you differentiation and a higher MOQ. Before paying for tooling, ask for the mould drawing, the material, the expected life of the tool and who owns it after the project ends.

Inspect before shipment, not after arrival

Agree on an inspection standard in the purchase order: sampling plan, defects that cause rejection, and the tests to be performed. At minimum, every unit should be powered on before packing, and multi-head fixtures should run through an ageing period. Ask for photographs of the packed cartons and the shipping marks.

Keep the documents together

Test reports, certificate numbers and validity dates, the approved sample specification and the final packing list should live in one folder per order. When a customer or a customs officer asks a question two years later, that folder is the answer.
