A quick Google search will show you that cities everywhere are starting to realize the cost savings in switching from legacy street lamps (old high-pressure sodium or metal halide) to LED street lights. What were once pilot-test programs are now full-fledged, citywide mandates.
Since LED lights traditionally use from 1/3 to 1/2 the power of comparable legacy lamps, the math is pretty straightforward. The benefits? Well, I can’t say it any better than the city of Boston …
Improved Lighting Quality and Public Safety Benefits
LEDs provide better, clearer, and more consistent light quality that makes Boston’s streets safer through:
- Fewer streetlight outages as LEDs have a life expectancy of 15 years, compared to 5-6 years of mercury vapor streetlights.
- A truer white light quality, which leads to better color rending, allowing colors to seem more natural.
- Minimization of light trespass onto homes and businesses by the “aiming”
