Ann Arbor Replacing Street Lights with LEDs

I'm back from a bit of a hiatus this past week - between vacation and a crazy work week, it's been a tough time for posting. But anyway, here's some good news from Ann Arbor, MI:

The home to the University of Michigan is replacing about 1,400 street lights with super-efficient LEDs. City officials say they are the first city in the U.S. to make the switch of all of its downtown lights.

The move will save the city about $100,000 a year in energy costs (wow!) and will pay for themselves in about four years. Not to mention the money saved from paying workers to change the lights: Mayor John Hieftje explained that the LEDs should last about 10 years compared to only 2 years with the old-fashioned bulbs.

Ann Arbor is home to the University of Michigan. Michigan State is in Lansing. Some people around here take that kind of thing seriously... :-)

Ann Arbor has also converted its street signals to LED lights, as well as the street light replacement program. That's not as big of an energy savings as the streetlights, but in both cases, there is also a significant labor savings from a less-frequent need to relamp the fixtures.
