Rigorous Raw Material Selection
Incoming Quality Control (IQC): Each batch of raw materials is inspected for lumen output, color temperature accuracy, thermal stability, and electrical safety before production.
Supplier Qualification: All partners are ISO certified and compliant with RoHS and REACH environmental requirements.





Advanced Production Process Control
Our production facility is equipped with automated SMT placement lines, precision soldering stations, waterproof silicone potting machines, and advanced assembly lines to ensure high product consistency.
In-Process Quality Control (IPQC): Multiple inspection points are implemented throughout the production process, including solder joint inspection, optical uniformity verification, and waterproof sealing testing (IP65/IP66). Standardized Process: Each product is assembled according to strict SOPs to ensure batch-to-batch consistency and minimize defects.





Comprehensive Final Product Testing
Aging Test: Continuously runs for 4-8 hours to detect early defects.
Photometric Analysis: Tests lumen output, color rendering index (CRI), beam angle accuracy, and energy efficiency.
Electrical Safety Test: High-voltage insulation and grounding checks ensure safe use in industrial and outdoor environments.
Environmental Reliability: Salt spray testing, vibration testing, and thermal cycling simulations ensure long-term durability even in harsh conditions.
Our product's average pass rate exceeds 99.8%, ensuring wholesale customers receive defect-free goods.
