LED lights: How bright should they be?

City council recently approved an agreement with Toledo Edison to replace all 28,000 streetlights in the city with LED fixtures by the end of 2021. The project will cost the city about $5.8 million, no matter how bright the bulbs, and officials estimate it will translate to about $580,000 in annual energy savings. The city is now debating between installing fixtures that have a brightness of 4,000 Kelvin or 3,000 Kelvin. The higher the number, the brighter and whiter the light is, officials said.
