New York replace subway tunnel lights with LEDs
Sure, changing the light bulbs in your house to compact fluorescents can cut your energy bills a bit and save you a few bucks. But if you're a municipal agency like the New York Metropolitan Transit Authority, with 60,000 lights to replace, those savings can add up fast.
The MTA is in the process of changing the lights in the New York subway system to LEDs. So far, the agency says it's changed 47,000 signal lights. When the upgrades are complete, the change could save the city up to $4.8 million per year, while reducing greenhouse gas emissions. And the LED lights are 150 percent brighter than the old light bulbs to boot.
The MTA is also replacing incandescent bulbs at subway stations with compact fluorescent lights.
