LED Street Lights - Data
LED Street Lights - Product Data
When we compare a LED street light with a traditional street light, the LED street light has more advantages than the traditional street light.
The following points should be considered when making a comparison;
1. The LED life time is longer than a traditional street light
2. One 150W LED streetlight can replace one 400W HPS light
3. Overall power consumption saving is 75% (150W LED v 400W HPS)
