Lighting is a safety-related part, so supplier selection should never be a price-only decision. The seven dimensions below help buyers quickly judge whether a lighting factory deserves a place on their approved vendor list.
Capability dimensions
- Optical and structural design: in-house beam simulation and regulatory know-how
- Tooling management: maintenance records, mold life tracking and backup tools
- Molding and coating: hard coat and metallizing under direct control
- Quality system: incoming, in-process and outgoing inspection forming a closed loop
Cooperation dimensions
- Batch traceability and 8D response speed
- Familiarity with target-market regulations
- Responsiveness across time zones
Turn this list into an on-site audit scorecard and combine it with sample testing. A well-run supplier will offer these documents proactively instead of waiting to be asked.
