Eco-friendly lighting company EcoLEDs.com has launched the brightest LED light bulb ever made available to consumers in the United States. Using just 10 watts and a single LED component made in the USA, the LED light uses just 1/10th the electricity of an incandescent light bulb and reduces CO2 emissions by 9,070 pounds over its life.
The EcoLEDs 10-watt LED light is available now. Incandescent light bulbs are now being globally recognized as extremely inefficient and outdated. Australia has already banned the energy-hungry light bulbs, and California is considering a state-wide ban. In time, all modern nations will ban incandescent lights due to their extreme inefficiency: they waste 95% of the electricity they consume as excess heat.
The mainstream push is towards compact fluorescent lights (CFLs), but consumers are not being told that CFLs contain toxic mercury. There's enough mercury in a single CFL to contaminate 7,000 gallons of fresh water, and if Americans continue to purchase CFLs -- then throw them away in local landfills -- the United States will soon be facing an unprecedented burden of toxic mercury in rivers, streams, croplands and oceans.

Are LEDs still $30 a bulb?
On sale now for ONLY $99.00.
The question is, of course, what is "its life?" There's a huge market difference if the LED costs $30 but lasts 1 year vs. 10 years.
I’d just want it in my laptop and extend the battery life to 10+ hrs. That’ll put a smile on my face.
Far more viable than the CFLs... But again, not all lighting types are effective for all applications. Insane that governments are trying to ban things that technology will eventually outmode.
with 95% lower cost of use over its lifetime, these LED’s will replace incandecents where its practicle.
LED’s last ages... I forget the exact ratings on them, but I have personally yet never seen an LED burn out, and I’ve been using devices with them for 20+ years. If their life expectency isn’t measured in decades I’d be amazed.
I have seen them and they have such a high color temperature that it is strainful to the eyes for prolonged periods of reading. Same as with most CFLs.
A hundred bucks for a lightbulb?! I don’t care how little electricity it uses there’s no way I’m paying $100 for a lightbulb. A total replacement in my home would cost nearly 4 grand, my first car only cost 5.
True, but over the lifetime of the bulb, that’s nothing...LED’s outlast incandescents by a factor of, IIRC, 50:1. You literally have to break the damn bulb to kill it. Today’s incandescents have a lifetime of 2000 hours - LED’s have a lifetime of over 100,000 hours and they produce significantly less heat.
Plus $10.00 shipping. They look more like a spot light than an area light, so might have limited application. I’ve been switch to CFs as I can, but I have a lot of light fixtures where they won’t fit.
Yes, but how often to your usual light bulbs fail when they have been on for a while, they usually break when they are initially turned on. I wonder how these eventually fail.

Answer my own question from the press release: "they last 50,000 hours before needing to be replaced." Under normal use (say, 8 hours/day), the LED should last 15 years or more.
By comparison, an incandescent bulb has a lifetime of 750–1000 hours. (Though for some reason, the overhead lights in my house burn out much faster....)
Factor in electricity savings, and a few strategically-placed LEDs could be a long-term savings. I can't see replacing every bulb in my house, though.
Haven't heard that before. If true, that's very bad news.
Get back to me when they aren’t that nauseating blue color.
I suppose the semi-conductor material will eventually no longer emit photons when a bias voltage is applied, but I agree, I’ve never known one to “burn out” after years of use. I would think in the case of these bulbs, the weak link is in the rectifier circuit.
