The folks over at Eternaleds, Inc. recently announced the debut of their HydraLux-4 LED light bulb, a light bulb that could change the way we live! (okay, perhaps I’m exaggerating a bit).

The liquid-cooling technology used in HydraLux-4 LED is the first of its kind. The bulb is surrounded by liquid, making overheating virtually impossible and cool to the touch no matter how long they’ve been on. LEDs are known to be far more energy efficient than the standard CFL bulbs, which don’t provide a full range of light. Fortunately this new invention gives a full 360 degrees of light.

While, the $35 price tag per bulb may cause sticker shock, the life time and efficiency of this bulb almost makes up for it. At 8 hours a day, the HydraLux-4 only costs $1.75 per year to run and uses 4w compared to the common 25w of incandescent bulbs; from there you can do the math. Furthermore, they’re rated for over 35,000 of use, that’s almost 4 years.

One great thing I like about the HydraLux-4 LED bulb is that it’s completely dimmable. If dimming is not enough, you can even choose from two available colors; Warm White and Daylight White and even install these bad boys outside.

If its pushes through, Eternaleds is planning to release 8w, 12w and 16w versions of HydraLux by the end of 2009. Each purchased bulb comes with a 2-yr warranty and 30 day money-back guarantee. Nothing is brighter and more reassuring than that!
