Eternal LEDS announces their 4W LED Hydralux-4 LED bulb which they say lasts 35x as long as a traditional bulb while saving $157 over the life of the bulb. The base includes liquid cooling in place of more traditional metal or fan cooling. The resulting LED bulb is fully dimmable, can be used indoors or out – and is cool to the touch. Expect 8W, 12W and 16W versions by the end of 2009. Cost is $34.99 and includes a two year warranty.
