How to Choose the Right LED Street Light for Your Road Project

When buyers compare LED street lights, the first question is usually "how many watts?" — but wattage tells you almost nothing about lighting quality. A 100 W fixture with good optics can outperform a 150 W fixture with the wrong distribution.

Start with the road class. Residential streets (P class) need different uniformity than main roads (M class). Ask your supplier for a Dialux simulation based on your pole spacing and mounting height, not a datasheet promise.

Color temperature matters for both safety and ecology. 4000K neutral white is the mainstream choice for urban roads; warmer 3000K is increasingly required near residential zones.

Finally, check surge protection (10 kV minimum for outdoor grids), IP66 ingress rating and the driver brand. The driver is the first component to fail — a good street light is a good driver plus good thermal design.
