LED Lights - The Future Of Lighting ?  

The Alternative Energy blog has a good post up on the new wave of energy efficient light bulbs made from LED's.

LED lamps were unthinkable until the technology cleared a major hurdle just a dozen years ago. Since then, LEDs have evolved quickly and are being adapted for many uses, including pool illumination and reading lights, as evidenced at the Lightfair trade show in New York this week.

More widespread use could lead to big energy savings and a minor revolution in the way we think about lighting.
