Contact UsEvery Chedina product undergoes a comprehensive multi-stage quality control process — from incoming material inspection to final aging tests — guaranteeing performance in the most demanding conditions.
All raw materials and components are tested against specifications before entering production. LED chips, drivers, housings — nothing goes unchecked.
Spot checks at every production stage: SMT soldering quality, assembly precision, thermal paste application, and waterproof sealing integrity.
100% of products undergo continuous aging tests in our laboratory — running for hours under rated voltage to detect early failures.
Random samples tested in extreme temperature chambers (-40°C to +85°C), high humidity, vibration, and salt spray environments.
Visual inspection, brightness measurement, beam pattern check, and waterproof IP rating verification before careful packaging.
Testing Facilities State-of-the-art laboratory equipment ensuring every product meets international quality standards.
Precise luminous flux, color temperature, and CRI measurement for LED performance validation.
Extreme temperature cycling from -40°C to +85°C to simulate harsh driving environments worldwide.
IP67/IP68 immersion testing with pressurized water jets to verify sealing integrity.
Simulates years of road vibration to ensure mechanical durability and connection reliability.
Continuous 24/7 burn-in testing for hundreds of units simultaneously to catch infant mortality failures.
Verifies light distribution and cut-off line compliance with ECE and SAE regulations.
“Every product that leaves our factory has passed 100% functional testing. We stand behind every unit we ship.”
