New York will replace all 250,000 of the city’s street lights by 2017, greatly reducing energy costs.
LEDs already have been installed in street lights along key corridors, most recently for Eastern Parkway’s pedestrian lights between Grand Army Plaza and Ralph Avenue in Brooklyn, on Manhattan’s FDR Drive, along Central Park’s pedestrian paths and on the “necklace” lights that adorn the cables of East River Bridges.
Compared to the current standard high-pressure sodium lights currently on streets, which last six years, LEDs can last up to 20 years before needing replacement, potentially producing up to an 80 percent savings on maintenance. All together, the 250,000 new LED streetlights are expected to be the largest LED retrofit in the country and save approximately $6 million in energy and $8 million in maintenance a year for a total of $14 million in longer-lasting, more efficient, greener lighting.
“With roughly a quarter-million street lights in our City, upgrading to more energy efficient lights is a large and necessary feat,” said Mayor Bloomberg. “It will save taxpayers millions of dollars, move us closer to achieving our ambitious sustainability goals, and help us to continue reducing City government’s day-to-day costs and improving its operations.”
New York has previously pioneered the application of energy-efficient lighting. It was the first large American city to use LED traffic signals, converting fixtures at all of the 12,700 signalized intersections citywide and producing an annual energy savings of 81 percent.
