False parameter labeling leads to insufficient illumination, fast light decay, failed project acceptance and safety risks.
Common tricks: hardware downgrade for low-price bidding, confusing parameter definitions, high-quality samples but downgraded bulk goods, lack of third-party testing.
Tips to avoid lighting procurement risks:
✅ Request LM79 photometric reports and IES files for exact models;
✅ Conduct aging sampling tests to verify lumen, IP rating and CRI of downlight, high bay lights;
✅ Add clauses in contracts to guarantee consistent performance between samples and bulk goods;
✅ Work with manufacturers with in-house lab and full aging inspection.
