Did you hear about a recent project we did that is saving King County energy, money and freeing up staff time? Last year, King County Road Services (Roads) replaced nearly 700 streetlights along various roadways with Light-Emitting Diode (LED) bulbs, a move that makes this year’s Earth Day on April 22 shine brighter. Compared to the old High Pressure Sodium Vapor lights we used, these new LED’s are an ideal choice because they last about 10 times longer, have a whiter light so colors are more visible at night, shine brighter and are easier to maintain.
The nearly 700 LED lights we installed throughout King County are expected to:
- Reduce energy costs by 54 percent or more than $57,300 every year
- Save more than 510,000 kilowatt hours of electricity, enough to power 84 homes annually
- Free up approximately 1,170 hours of maintenance staff time so they can focus on other Roads priorities
- End up paying for themselves in less than eight years
- Reduce light trespass on adjacent properties and up-light impacting visibility of stars in the night sky
The nearly $550,000 conversion was completed last fall, and we’ve already seen energy costs cut nearly in half at 20 of the busiest roadways and intersections, like Novelty Hill Road and Woodinville-Duvall Road. We’re happy to do our part to help assure that our roadways will be well-lit and sustainable for years to come.
