And then a light went off...

Meet the Geobulb. The Geobulb is an LED light that is intended to replace a 60 watt incandescent bulb. The current wave of compact fluorescent bulbs are but a stop along the way to a world illuminated by LEDs. LED stands for light-emitting diode. An LED is a super-efficient method of light generation that features no breakable parts like the tungsten filament in a standard incandescent bulb. What's more, there's no mercury in it, unlike compact fluorescent bulbs. This lowly bulb produces the equivalent light of a 60 watt incandescent bulb (800 lumens) while using only 8 watts of electricity. Pretty cool. What's even cooler is that it's available in three color temperatures: cool daylight, warm white and soft white. Although the price on these things is just starting to drop (this Geobulb will set you back $120 and that's if you can find one), their long life puts even a CFL to shame. The expected lifetime of this Geobulb is 30,000 hours. What that means in the real world is that if your turned this thing on for 12 hours a day every day, you could continue to do so for the next seven years before you'd need to start thinking about replacing it. The Geobulb is available through C. Crane.
