Score LED lighting vendors on specs, certification, lead time and after-sales, not unit price alone.
Beyond the UGR number, check the shielding angle (>=30 degrees recommended) and real install results; glare varies with mounting height.
During sampling, run aging, dimming, CCT and drop tests in parallel; mass production only after samples are approved.
Thermal design drives lumen depreciation: die-cast fins plus thermal compound is proven; keep junction temperature below ~85C, backed by LM-80 reports.
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.
