Now A Single LED Could Replace Your Household Bulb
Imagine lighting your house with LEDs? Well very soon you will be able to, after the introduction of new LED technology that can produce light energy equivalent to a household bulb. The new LEDs provides light output of more than 1,000 lumens (measurement of light output or brightness) which is the same as produced by any standard household bulb.
The single die LEDs from Cree, includes semiconductors and solid state lighting devices able to produce 1,050 lumens in cool white and 760 lumens in a warm white version when operated at four amperes. The Efficiency (output light energy per watt) is 72 lumens for cool white and 52 lumens for warm white devices. These LED’s provide higher efficacy levels than any of the other available light bulbs:
“Cree’s XLamp(r) LEDs are the best-performing commercially available LEDs, but we won’t be satisfied until light bulbs are obsolete,” comments John Edmond, Cree co-founder and director of advanced optoelectronics. “We’ve worked 20 years to achieve lighting-class LED performance, and we still have plenty of ways to advance the technology further.”
No details were given of how much the new LEDs would cost, but they will be available in 12-24 months. I’d imagine that they won’t cost less then lightbulbs. Regardless, I’m sure we’ll have some very bright Santa grottos to look forward to in the future!

These are supposed to be different than flourescent’s right? We installed some of those, and they give off a glowy light that isn’t as nice as a regular light bulb. So, hopefully they LED’s don’t do that.

I do find that many of the LEDs that i have come across do not give that nice glow which you really need on those long winter nights at home. But i could see the point if they could get this right. You also have to look at the shelf life or a LED but i am guessing that it will be much more energy friendly

The LED shelf life is many many more times that of CFL and incandescent bulbs. They draw a fraction of the power and also operate cold, making them very versatile. I will be interested to see how well Cree’s bulbs live up to the claims as I am hoping to be able to replace all the bulbs in my house for LED’s in the near future. I recently replaced my GU10 light fittings with LED bulbs as these are readily available and have been very impressed with the light they produce.
