Boston and Los Angeles have installed LED lights

So far, the town has installed about 200 light fixtures. The switch is expected to save about $225,000 a year or $2.2 million over the fixtures' 10-year life.The Long Island Power Authority said LED streetlights can use 50 to 70 percent less energy and last three to five times longer than high-pressure sodium lamps.

Additionally, Boston and Los Angeles have installed LED lights and other communities have plans to make the change.Apart from Long Island, some towns are converting to induction lights, which are similar to fluorescent lights and also cost less to use than traditional lighting.

Philips cooperates with the Rijkswaterstaat (RWS - the Dutch highway authority), contractors Gebroeders Van der Lee and LED Linear high bay light consultants Spectrum, has installed LED lighting along a 7km-length of the A44, one of the busy highways of Amsterdam.

In comparison with around 60% of the energy consumed by the Netherlands’ motorways and waterways used for lighting, the led high bay light installation on the A44 will save some 180,000 kWh per year – the equivalent energy consumption of 50 households.
