Long Island, Smithtown in America is replacing over 10 percent of its streetlights with LED.
 
According to Traffic Safety Director Mitchell Crowley, who is overseeing the project, the new lights, paid for with federal stimulus money through a grant of more than $1 million, will convert about 1,500 of the town's 11,600 streetlights to LED.

So far, the town has installed about 200 light fixtures. The switch is expected to save about $225,000 a year or $2.2 million over the fixtures' 10-year life.

The Long Island Power Authority said LED streetlights can use 50 to 70 percent less energy and last three to five times longer than high-pressure sodium lamps.

Additionally, Boston and Los Angeles have installed LED lights and other communities have plans to make the change.

Apart from Long Island, some towns are converting to induction lights, which are similar to fluorescent lights and also cost less to use than traditional lighting.
