New York City Plans to Replace 250,000 Street Lights with LED




New York City is transitioning its 250,000 street lights to energy-efficient LEDs in an upgrade that should be completed by 2017.

The plan was announced by Mayor Mike Bloomberg, noting that the savings can reach $14 million a year due to less power consumption and longer lifespan of the LED bulbs.

New York’s streetlights currently produce a baleful orange glow by electrocuting vaporized sodium atoms. Sodium bulbs have been around since the 1930s and are commonly used in cities. But LEDs last longer (20 years) than sodium bulbs (6 years), tend to be more efficient, and give off cleaner, more illuminating light.
New York has already gone to LEDs on select streets in Manhattan, Brooklyn, and in Central Park. The  $76.5 million project will replace streetlights in waves of 80,000 and, and if projections bear out, save $14 million in maintenance and energy annually.

New York’s transportation commissioner, Janette Sadik-Khan, said in a press conference, “These 250,000 new lights will redefine our roadways and neighborhoods, bringing in clearer, whiter and more attractive lights to our 6,000 miles of streets and 12,000 miles of sidewalks.”

Bloomberg and company say New York City’s LED project is the world’s biggest—but it’s hardly the first.

Los Angeles, for example, recently finished replacing just over 141,000 streetlights with LEDs. The city says savings have so far outstripped projections (63% cost reduction compared to the forecast 40%), and light pollution is much reduced because LEDs can be better directed, preventing unintended light leakage.

Other US cities upgrading to LED streetlights include Seattle, Las Vegas, Austin, and San Antonio, among others. Buenos Aires will soon install some 100,000 LED streetlights. More may follow. According to Navigant Research, shipments of LED streetlights are set to rise from 3 million in 2012 to 17 million in 2020.

Meanwhile, in Europe, the Netherlands is experimenting with getting rid of street lights altogether in favor of crazy futuristic glow-in-the-dark road paint that also responds to extreme weather.
