How importers should compare LED wattage claims
Wattage is not brightness. Importers comparing LED fixtures should look at lumens, efficacy, optics, and thermal design—not the biggest watt number on the carton.
Lumen and lm/W
Ask for useful lumens and efficacy. A lower-watt high-efficacy fixture can outperform a hotter high-watt unit.
Beam angle changes how bright a surface looks.
Thermal and driver quality
Poor heat paths kill LEDs early even if initial lumens look fine.
Driver brand and surge protection matter on unstable grids.
Apples-to-apples quotes
Normalize CCT, CRI, IP, and lumen package before ranking price.
NMF helps rewrite RFQs so factories quote comparable products.
