Every linear light fixture undergoes continuous power-on burn-in testing before shipment. The finished lights are neatly arranged on test benches and kept powered for hours, simulating real long‑term working conditions on site. During the aging procedure, our team monitors lighting performance, driver stability and heat dissipation in real time. Defective products with flicker, dim output or unexpected shutdown will be screened out. Only qualified units that successfully pass the aging test will be packed for delivery. This strict procedure ensures reliable performance and greatly reduces after‑sales failure risks for your projects.
