HydraLux-4 is First Liquid Cooled LED Lightbulb

While those of us trying to save on our energy bill are using CCFL lightbulbs, the real future of efficient lighting is in light emitting diodes, or LEDs.

Los Angeles-based Eternaleds just unveiled its latest LED bulb product, the HydraLux-4 which uses just 4W to give off the light equivalent of a 25W incandescent bulb. What really sets the HydraLux-4 apart is that it's liquid cooled – a world's first.

"Most other LED globe shaped bulbs use metal or fans to surround the bulbs to keep the components inside cool. This design only allows light to come out of the top half of the bulb, like a spotlight." explains Jeff Chan, founder of Eternaleds, Inc. "This is the first LED light bulb to give true 360 degree light and really opens up applications that people can replace with LED lighting."

Eternaleds claims that the HydraLux-4 is a better 'green' solution than CCFL bulbs for chandeliers, sconces and decorative lamps.

The Eternaleds HydraLux-4 comes in two colors, Warm White and Daylight White, and can be ordered directly from Eternaleds.com at a list price of $34.99. It's an expensive investment, but it's rated for 35,000 hours; and at 8 hours a day, the HydraLux-4 costs around $1.75 per year to run, saving an average of $157.00 over the lifetime of the bulb in electricity and bulb replacement costs.

Eternaleds plans to announce 8W, 12W and 16W versions of the HydraLux by the end of 2009.

    Really cool. I'll buy them when they're a bit cheaper.

    What we really should care is the comparison to a CFL. Accroding to Wikipedia, CFLs use 1/3rd to 1/5th of the energy of comparable incandescent bulbs, so we are roughly speaking 6-8 watts CFL is comparable to a 4W LED light bulb. Not so impressive, but still an improvement. At least until we get to the sticker shock. Since I've been using CFLs at home exclusively for years, it doesn't make much sense to upgrade to LED. Perhaps in a few years when the long lived CFLs start to die, or perhaps a decade until I run out of the spares I already have as well...

    In general i think they should at least be shaped like the bulbs they are replacing. Many people are so use to what a A19(normal bulb) looks like that they do not tend to like these new ones.

    It will be nice to see a 25 watt equiv though. 40 is just too much in my fan.

    Correction: 5-8W CFL equals 4W LED. Sorry for the typo in my previous post.

    I would get a couple if the prices came down. The one thing that annoys me about CFLs is that it takes a few seconds (sometimes more) to warm up (reach full brightness)... also no mercury is a plus

    well it's less than i figured it would be (i figured close to/over $50) and an led light would last for one heck of a long time, but i never figured an led light would get hot enough to use liquid cooling

    Unfortunately all of the LED lights are low wattage, if they can give me something equivalent to a 40 or 60 watt incandescent then it will be useful, but a 25 watt incandescent just isnt enough to light a room.

    Cool. :3 I wouldnt mind replacing all my bulbs once they start costing 10-15 bucks a pop.
