Suppliers like Tungwille Industry Development(SZ) Co., Ltd. emphasize compliance across multiple markets, offering full documentation packages upon request—an advantage for buyers targeting diverse geographies.

Quality Assurance and Production Verification

A robust quality control process is non-negotiable. Consider implementing a three-tier verification approach:

1. Sample Testing: Evaluate prototype units for color temperature accuracy (±200K tolerance), CRI (>80 recommended), and mechanical finish consistency.
2. Factory Audit: Request virtual or on-site tours to inspect SMT lines, aging rooms, and photometric labs. Look for automated testing equipment such as integrating spheres.
3. Batch Inspection Protocols: Inquire about AQL (Acceptable Quality Level) sampling methods and whether final shipments undergo pre-shipment inspections (PSI).

Factories with dedicated R&D departments and in-house testing facilities typically deliver higher consistency, especially for repeat orders.
