More cities tap stimulus package for LED streetlights

Cities across the USA are making their streetlights brighter and greener by switching to LEDs.

Light-emitting diodes produce light when exposed to an electrical charge. They cost more than traditional lights, but last longer because they don’t have filaments and use less electricity.

Several cities, including Ann Arbor, Mich., and Anchorage, have installed LED streetlights, and dozens more are planning conversions. At least 30 cities have asked for more than $104 million in federal stimulus funds to help them make the change.
