I think that this is far, far more viable than the florescents. If, for no other reason than the color and intesity of the light can easily be changed.

So it's expensive now....so were CFL's, 5 years ago. The price will come down. This is a technology that I can get behind.

Explain how this is supposed to replace a 100W bulb?

A 75w bulb from my bulb shelf: 1040 lumens.
This bulb: 400 lumens.

Also notice that the details page at the vendor spends about 80% of the time talking about saving the earth, but provides only sketchy information comparing the quality of the bulb with the cheaper alternatives.

If you haven’t already, convert all your flashlights to the LED bulb version. You won’t be sorry. Especially if you live in hurricane or earthquake or in fact any area where an emergency might hit — The LED flashlight bulbs improve light output while at the same time dramatically increasing ruggedness and battery life.

The dreaded Walmart is the place to start. While you are there check out the long life rechargeable batteries, and save even more money.

Emergency flashlights stored in cars should be switched over to LEDs and Lithium batteries so they will be there and working when needed. Lithium batteries are the only ones that can take the heat and work when needed.

The lowly flashlight can be your most important emergency tool, make sure it works for you. I am partial to Maglites, cheap and the work, the new LED versions are the best.

Hey, I own no stake in any of this stuff, except for being in the path of hurricanes year after year where the power can go off for days or weeks at a time.

LEd bulbs for the home are still a little too expensive, but the claims of 100,000 hour life and large energy savings are real. Most cities around here are converted to LED stop lamps and they claim the costs saved because of the cost to roll a truck to replace a bulb are worth it. Big fan of LED bulbs here, just not the price :<)

It uses 10.8 watts and produces 400 lumens. A standard 40 watt incandescent bulb will put out about 460 lumens total, compared to this $99 LED’s 400 lumens. This super expensive LED bulb is getting about 37 lumens per watt, compared to around 12 lumens per watt for a 40 watt incandescent bulb. Standard compact fluorescent lightbulbs will put out anywhere from around 55 lumens per watt on up to 70 lumens per watt or so. A 32 watt four foot fluorescent T8 tube in a fixture with a good electronic balance can get up in the neighborhood of 100 lumens per watt.

LED lights are not ready for prime time for use in general home lighting. They’re super expensive. The light they produce tends to be really weak, and not particularly pleasing to look at. The companies that push them really seem to be engaging in some over the top false advertising. Someday LED technology will mature and we’ll all want to use them in our homes to replace incandescents and most fluorescents, but that time hasn’t come yet.

Here are the specs on the bulb:
