- Clarify if lead times include shipping or are production-only
- Verify if they have backup production facilities
2. **Can you provide test reports from accredited third-party laboratories?**
- Specify required certifications (UL, CE, etc.)
- Ask for photometric reports and LM-79 tests
- Request thermal and vibration test results
3. **What is your quality control process and failure rate?**
- Ask about their QC checkpoints (incoming, in-process, final)
- Request annual failure rate statistics (<0.5% is good)
- Clarify warranty terms and replacement procedures
4. **How do you handle intellectual property protection?**
- Request their IP protection policy documentation
- Ask if they have experienced IP disputes
- Clarify their approach to custom designs and molds
5. **What after-sales support and spare parts availability do you offer?**
- Specify warranty period (typically 3-5 years)
- Ask about spare parts availability for 5-10 years
- Clarify technical support response times
### Sourcing Best Practices
- **Verify supplier credentials**
- Check Alibaba Gold Supplier status with Trade Assurance
- Request factory audit reports (SGS, TÜV)
- Contact at least three references
- **Request samples for testing**
- Test in actual operating conditions
- Measure light output and energy consumption
- Evaluate build quality and thermal management
- **Negotiate terms carefully**
- Specify payment terms (30% deposit, 70% before shipping)
- Include quality penalties in the contract
- Clarify shipping terms (FOB, CIF, DDP)
- **Plan for logistics**
- Consider sea freight (20-45 days) vs air freight (5-7 days)
