Lighting Science Group Recently Joined Washington DC Mayor Vincent C Gray and Officials

Lighting Science Group, an LED lighting company, recently joined Washington DC Mayor Vincent C Gray and officials from the District Department of Transportation (DDOT) and the Department of the Environment (DDOE) to celebrate the completion of the first phase of the relighting project that will save the city tens of thousands of dollars each year in energy costs. Part of the mayor's larger vision for a sustainable DC, Lighting Science Group's energy-efficient, long-lasting street lights have replaced old, inefficient lights and will cut the district's annual carbon dioxide emissions by 719 tons. Gray said there are already results that show these new light fixtures are saving energy - 57-60% - compared to the old mercury vapor and high pressure sodium lights. Gray also pointed out that the District would save huge amounts on energy costs if the area's LED program was expanded to all 70,000 street and alley lights. Source: DIGITIMES
