Ann Arbor, Michigan will be the first US city to convert their downtown streetlights to all LED. The city will start installing LED streetlighting in February 2008. The city says they will get a 3.8 year payback from the initial investment and then save money for the long life of the bulbs, which require less energy and last longer.
The City of Ann Arbor paid $1.39 million—25 percent of our energy budget—on traffic signals and streetlights last year. The cost would have been higher had the City not begun replacing incandescent traffic signals and pedestrian crossing signals with LEDs back in 2000. The replacements made so far are saving the city $49,000 annually, but the bigger savings opportunities are in street lighting, which accounts for 92 percent of that $1.39 million annual cost.
