Cheap, super-efficient LED lights on the horizon

This is a major breakthrough. 

Cheap, super-efficient LED lights on the horizon - tech - 29 January 2009 - New Scientist

Incandescent tungsten-filament light bulbs face a global switch-off as governments push for energy efficient fluorescent lamps to become the standard. But the light could soon go out on those lamps too, now that UK materials scientists have discovered a cheaper way to produce LED bulbs, which are three times as efficient as fluorescent lamps.

Although the ultimate dominance of LED lights has long been predicted, the expense of the super-efficient technology has made the timescale uncertain. The researchers now say LED bulbs based on their new process could be commercially available within five years.
