World’s First Liquid-Cooled LED Lightbulb Perfectly Pairs With Silly Gaming PCs

What the hell is that crack about "silly pc gaming machines"?
YOUR the one who is silly!

Anyone got a comparison for how much a traditional incandescent and CCFL cost in electricity per year & upfront?

I thought LEDs are not supposed to generate heat.

I think I'll wait a year or two for the manufacturing to allow a cheaper product. Very 'cool' though.

@bosskev:

Wow! I didn't even see the water in the pictures, but the video really shows that it's a lightbulb with water in it. That's insane! ...and wicked cool! Not to mention ultimate money savers. I can't wait to get my hand on some of these.

@shockwaver: That's still a big problem with LED lights, they just aren't available very bright. Even the ones that say they replace 60W bulbs are usually "exaggerating" quite a bit.

I don't know how useful liquid cooling is. It will delay the bulb from heating up, as the liquid absorbs the heat, but you're still producing the same heat and eventually it will be hot. In a 4W bulb it may not be relevant in the time the bulb is on, but scale up to a 12W or 20W and it's going to get hot, and stay hot when you turn it off, unless you add radiator fins like every other LED bulb already has.

No ghastly green color to match compact fluorescents?

so, these put off less light then a 25w bulb? The problem I have with my CFLs, is I just can't get the room to fill with light in the same way, and this is even dimmer? I'd love to save even more energy, but not at the cost of even more light.

@AlexSea: "..the touch thanks to the.." though the writing does overlap the picture in Chrome. Then finishes the rest of the sentence beneath the images

The lighting seems much more natural.
Though daylight white is kind of bluey and weak, I suppose it would work great as a bedside light in the morning (blue lights are better at waking you up)
Is it the water than aids with the natural colours or does the water just mean you can unscrew a cool light bulb straight away (their example)

Hmmm, I picked up a few packs of the LED bulbs from Sam's Club a few months back and I love them. I believe it was $16 for a pack of three and they use about 4W a piece.

what does it mean when the line that says 'other LED lights, cool to' overlaps the picture below it? Is it just formatting on gawker media's part, or is firefox 3.5 rendering things wrong? just curious, i'm not trying to be a peckerwood.

Daylight White does not look good in a home. But I would love to be able to turn all my lights in the home into LED. I did so with the Christmas lights already. But at $35 a bulb, that's a little to much for redoing my whole house.

OMG, the video on their site is SO trippy, watching the liquid swirl around like a half-filled snow globe! You really can't appreciate the "liquid cooling" from the still pictures above, go check out the video.

@Geisrud: EXACTLY!!!!!

Heck I think the smallest ones I have are 35 Watts and I use them in sets of no less that 5 or 6.

My single bulbs are no less than 60 W to 100 W.

We don't need more energy efficiency is stupid light bulbs... we need MORE POWER !!!!

Just how in hell are we going to chrage all the new plug-in hybrids and o-so-coveted full electric vehicles?

@Frizzaper: Even if the "harmless paraffin oil" shorts out anything inside, hopefully your house is wired with GFCI outlets. In which case, a breaker would pop instantly.

@Blake380:

Very little normally, but it's one of the problems with room lighting bulbs - they can make them very bright, but they heat up, dramatically shortening the life of the LED. That's why most lightbulb replacements have cooling fins (well, that and the power adapter built in!)

@Geisrud: I do.

@Frizzaper: Let's try some logic. Water is a liquid. However, not all liquids are water. See? Easy.

takeshi

@mfusion: Ah, okay. Thank you for clarifying that.

Blake380

@Blake380: all lights produce heat. LEDs are just more efficient than others at not losing energy to heat than others.

@Geisrud: 'Paraffin oil' = 'lamp fuel'. I've got a bottle of it sitting in my kitchen waiting to go in the various oil lamps when the hurricanes hit.

@Geisrud: That's exactly what I was thinking. Not only that, but it looks dimmer than the 25W bulbs in the comparison shots. LEDs still have a long way to go.

@Jonhy: The average CFL is a foolish purchase. Manufacturers use cheap electrolytic capacitors that overheat (in the usual bulb-down mounting position) and burn out long before the rated lifetime of the bulb--usually within a year, in my experience, especially for the crappy CFLs that Costco sells and many people buy. I replace those caps to revive the lights, but I doubt that most folks would want to do that. So, the cost of electricity isn't the most important factor in the economic calculation. On the other hand, I have six 18W Panasonic EFT18LE-T compact fluorescents for which I paid $10 each in 1992, and they're all still working just fine in daily use (bulb down, too). Vastly more economical than these LEDs!

@Frizzaper: We occasionally drop the 220V, 40A shore power line for our boat into the water. The result is not the world blowing up, just an instantly-popped circuit breaker. Besides, a dropped incandescent lamp, which happens all the time, is vastly more dangerous (hot, with exposed wires). You'd probably have to give this little (and presumably plastic) thing a good hard blow with a hammer to break it, and even then the liquid would be harmless.

CAVEperson

@Frizzaper: From TFA - "Not to worry, if you drop/break it - the liquid inside is harmless paraffin oil that has been tested and certified safe to UL and ROHS standards."

only consumes 4W of electricity (compared to a 25W incandescent)

I'll take some, as soon as it comes in UV reactive green. I have to match my system's cooling after all.

bitgod

I realize it's not a whole lot of liquid, but it strikes me that electricity+water=accidents waiting to happen. Assuming the bulbs are assembled perfectly, what happens when you knock a lamp over with one of these bulbs in it?

Frizzaper

as far as I know they are not the first to come up with the liquid leds, I have a prototype in my office I got from fiera luce and I believe taiwanese guys did them in the first place in 2005-6 (http://www.liquidleds.com.tw/style/content/CN-062a/about.asp?lang=2&customer_id=2023&name_id=80262)

the problem is that when things are typically water- or liquid-cooled, it works because the liquid is circulating and thus, dispersing the heat that it absorbs. since this liquid is just going to sit there, i don't see how it won't just heat up eventually and act like a little liquid down comforter, keeping the inside of the bulb hotter even after the light is turned off.

@jdale: true, the liquid will eventually get hot. the only plus side would be that the larger surface area at the exterior of the bulb provided by the liquid reservoir would dissipate heat faster. similar concept to the LED bulbs that have fins.
