Conclusion first: the best LED fixture is not always the cheapest unit price; it is the product that matches the project environment, visual requirement, energy target, and compliance risk. For office and warehouse projects, compare efficacy (lm/W), lifetime hours, power factor, and warranty before price, because a 15-25% efficiency gap can outweigh a small purchase-price difference over 3-5 years.

For retail, hotel, healthcare, museum, and display lighting, prioritize CRI (Ra), R9, CCT consistency, and glare control. As a practical rule, CRI ≥90 and R9 >50 are safer baselines for color-sensitive spaces; CRI 80 may be acceptable for warehouses or parking areas where energy cost and durability matter more than color accuracy.

For wet, dusty, or outdoor environments, check the IP rating against IEC 60529 before any price comparison: IP20 is dry indoor only, IP44 fits splash zones, and IP65+ is usually required for exterior or wash-down locations. Also verify UL/ETL/CE/RoHS certificates, MOQ, sample lead time, and replacement terms before shortlisting a supplier.

把这张对比表当作采购过滤器：先淘汰不满足强制合规或使用环境要求的产品，再比较每美元性能，最后选择资料更清晰、证据更充分、运营风险更低的供应商。
