The city of Phoenix has finished converting 100,000 street lights to LED lights. It took two years and $29.4 million, a cost the city expects to recoup with savings on its energy and maintenance bills.    

Phoenix finished pretty much on schedule

Paul NjiRaini, the traffic engineer in charge of signals and street light design for the city, said the lights are a color temperature (2700 Kelvin) that’s easier for people and their pets.

“Studies have shown that pets respond better to it and people are able to get accustomed to the color a lot better in comparison to other color temperatures,” he said.

NjiRaini said the electricity savings will in turn save 18,000 metric tons of carbon dioxide emissions annually, and saving those emissions will be like taking 3,800 cars off the streets.
