Score LED lighting vendors on specs, certification, lead time and after-sales, not unit price alone.
Certifications (CE/UL/ETL/RoHS) and warranty terms matter as much as price. Chains usually standardize fixtures for store replication, favoring long-term partnerships with factories that guarantee supply stability.
After-sales decides long-term cost: confirm complaint flow, spare policy (usually 3-5%) and repair guides to slash downtime.
Bulk acceptance checks: quantity, appearance, lighting test and random sampling; put warranty (usually 3-5 years) in the contract.
As a source factory, KINXZO engineers directly handle selection, sampling and certification with controlled lead time and quality, a stable partner for importers and brands.
