NYC Is Replacing Its 250,000 Street Lights with LEDs

In recent years, we've watched with wonder as boring old yellow halogen car headlights have been replaced with futuristic, Tron-like LEDs. Now, that transition is about to take place on the city scale, as New York City prepares to replace its street lamps—all 250,000 of them—with LEDs. Mayor Bloomberg announced the massive project on Thursday, pointing out straight away that the shift to LEDs would save the city $6 million in energy costs and $8 million in maintenance—that's $14 million total, math whizzes—every year.
