This 13 watt bulb, the Evolux by EarthLED, is said to be first LED light to be able to replace a 100 watt incandescent. The lifetime of this bulb is rated at over 50,000 hours — which is five times longer than a compact fluorescent bulb. Other advantages of LED bulbs is their ability to brighten instantly, and be switched off and on rapidly without problems. They also contain no mercury. LED-based bulbs do, however, require more energy to manufacture that CFL or incandescents.

The Evolux uses a CREE light engine, and it contains a small fan to cool the circuit board. EarthLED has a video of the bulb in action, and also some photos showing the type of the light it renders. The Evolux bulb sells about $90 right now. If you are serious about energy efficiency, or if you’re using solar power, this might be the bulb for you.
