The true white LED is estimated to be about one fifth of the wattage currently required by the faux white LED... When it hits the marketplace, there will be massive retrofitting and a fond farewell to the now widely used energy efficient T8 lamp and ballast...

Because LED lights are a low energy and low heat alternative to conventional traffic lights, they are perfect for many cities closer to the equator. However, when used in northern cities, such as any city in Alaska, they have a fatal flaw. They do not produce sufficient heat to melt snow and ice which forms on the surface of the light. This may result in large balls of snow and ice which may produce little or no light As much as I am for energy efficiency, this is a very bad idea that was obviously not well thought through.

They could use the same budget to convert at least twice as many fixtures to low pressure sodium, which are still far more efficient than LEDs. That way they'd save even more on their electricity bill. If they are using 50% less electricity by installing LED lights, I’d like to know what they were using before.
