The streets of Buffalo, New York are a little brighter these days. The city recently updated their street lighting to LED, increasing security, safety, and savings for the city.
During 2011, commercial and institutional buildings, and street and highway lighting, consumed "about 275 billion kilowatt hours for lighting or 21 percent of commercial electricity consumed," according to the U.S. Energy Information Administration.
Cities are finding out quickly that changing out older streetlights for LED lamps can reduce energy use. Compared to high pressure sodium lamps, LEDs use less energy, and also handle outdoor temperature changes and moisture better. Plus they are more attractive for use as outside security lights, and provide better directional lighting.
"LED streetlights can quickly show a return on investment by offsetting the high up-front expense with lower energy costs, longer life, and reduced maintenance."
