HydraLux-4 is First Liquid Cooled LED Lightbulb

By - Source: Tom's Hardware US | B 31 comments

This LED is cool. Liquid cooled.

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.

    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

    Neat! I hope to more of these in future!

    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.

    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.

    Damn, I'm picking these up soon. I hope I can get them in volume packages, maybe 100$ for 4. Then I could save 521$ a year. Very cool.

    read the article.

    @hunter35:
    GeoBulb® LED Light Bulb (Cool White)
    "It puts out more light than a standard 60-watt bulb but uses less than 8 watts. LED bulbs last 3 years of continuous use or 10 years at about 8 hours per day."
    Sounds good to you?..;)

    It is cool if I have extra $99.95 to spend on a light bulb....>_<

    i don't have a thing for high power/cooled LEDs, they are supposed to be efficient like the low power LEDs commonly used.
    will wait for OLEDs for household lighting.

    Philips has the Master LED lights, but they are only available in Europe as they using 230 volts. First saw these online sometime last year.

    Nice, but still missing replacement for my 50W Hallogen MR20 flood bulb. These get extremely hot and being receded, it kind hitch me with the risk of fire. LED lightning would greatly reduce dissipated heat AND save me lots of cash (15x50 = 750W).

    I haven't noticed that any LED needed cooling. Perhaps some high wattage industrial app but you don't see cooled LEDs at homedepot and such. 4 watts can't possibly burn down your desktop lamp right?

    It may be the transformer that step the power down, but even then, i find it hard to see that much heat. Since everyone is doing it, there is a reason, or they are just trying to make it look better like some motherboards have cooling that is not needed at all.

    I've seen the website pictures, and it's clear that the daylight white (the first bright white on the video) is about equal to a 25W lightbulb.
    The 'Warm White' gives off considerably less light, and is more comparable to a 20W lightbulb.
