For Energy Conservation
Streetlighting is one of the major applications for LED lighting for reducing the maintenance and replacement cost due to a longer life-time, for minimizing distortion and glare, for providing a brighter white light and reducing the electricity consumption in 50%. For streets, public parks and parking lots, LED solutions are the best choice. Below are some cities that already adopted the LED streetlighting as a solution for energy conservation. Other cities like San Francisco-CA, Oakland-CA, Raleight-NC, Minneapolis-MI, and Racine-WI are also involved or have plans to retrofit outdoor lighting.
Ann Arbor, MI
As reported, the Ann Arbor is replacing 1,400 downtown lights by LED streetlights. The installation is expect to save about $100,000 per year. The target is to extend the streetlights retrofit for neighborhood streetlights, with the eventual goal of replacing all of public lighting with LEDs. This plan should cut Ann Arbor's public lighting energy in half reducing greenhouse gas emissions by 2,200 tons of CO2 per year."
Anchorage, Alaska
Anchorage conducted extense study. The LED streetlights are expected to use 50 percent of the energy, saving the city $360,000 per year.

Welland, Ontario
Welland plans to retrofit all streetlights with LEDs, aiming to save $253,980 per year. Welland has already installed 50 LED streetlights to revitalized specific areas.
Fairbanks, Ak
Fairbanks will replace streetlights with LEDs. City officials believe the new lights will save the city hundreds of thousands of dollars in electricity and maintenance costs reducing consumption by more than one-third. The pilot project is to install 104 LED lights to see how much the city can save and what the public thinks about the lights. The city expect to spend about $2.5 million to relace all 2,800 city's street lights.
