Oyule do anything for a buck, designers! Lighten up and create something affordable. You say watt's $650 for a well-designed product, I say you're dim if you expect anyone to buy it. You may think you could filamint with all the money you'd make, given the difference in price and the cost of materials, but in this burned out economy you're not going to seem so bright.
@njdevil: Thanks! And not that it's any of your beeswax, but my dad always said, "Son, stick to language jokes. If you had a parrafins you'd be a linguistic shark, lumen over the rest of us fishes, ready to wax on at length."
imagine a lightbulb with the guts still inside filled with a flammable liquid. When plugged in the coil would spark the flammable liquid causing an small explosion but don't forget its housed in very sharp easy to break glass that would go flying around at high speeds (maybe not).
Edison's little known precursor to the electric light bulb, apparently. It is a beautiful design, but while electricity has gotten expensive, perhaps not $650 expensive.
@Monty: Or you can go on instructables and they will tach you how to make these for free.... I have several... I used old lightbulbs cut up pieces of cotton sock and some washers... oh and lamp oil and little magnets. It took me 15 min for one... $650 is for suckers.
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: 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."
@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!
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!)
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.
@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.

A: Just one. But it takes them all night. And when they're done, the washing machine doesn't work right.
