By now, you may have noticed that crosswalk signals have gotten a lot brighter, and a lot whiter. At the same time, traffic lights have have become pixelated and more clear. It’s all part of the LED revolution that’s sweeping cities and companies alike, saving energy and huge amounts of money in the process.
By replacing old traffic signals with LED powered signals, the NYC borough of Queens alone is saving over $600,000 a year, and other cities (and their taxpayers) are enjoying similar cost savings. Companies too, can enjoy the benefits by replacing traditional bulbs in places like hallway lighting, hotel reading lamps, and aircraft cabins. Enviropundit points us to more. There is also a discussion going on at Treehugger.
