The jury is still out on that one.
LED (Light Emitting Diode) bulbs are many times more efficient than even CFL light bulbs. They last many times longer as well. The technology, however, is so new that 1) they are still very expensive, and 2) not all the bugs have been worked out. I predict, however, that it will be the lamp of choice within the next 5 or so years.
I saw an ad for a mere 7 watt LED flood light for $49. Yikes!!! But remember when a CFLs were $25 a pop? They are now down to a couple of dollars, perhaps foretelling the prices for LED lights in the not-too-distant future.
Here are what LEDs look like:
Cool. They look like either a shower head or cuff links. With LEDs, energy flows through a semi-conducting material and lights up the tips…like those fiber optic lamps in the 80’s.
There are a number of manufacturers all vying to become the standard (think VHS and Beta….I preferred Beta. It was more compact and better quality. But I digress.) LED lighting is still evolving, so give it a few years to work the kinks out. For now, LEDs are best used for any type of down lighting, Christmas tree lights, night lights, exit signs, clock radios, and cuff links.
Peace – Out

LEDs are not many times more efficient than CFLs. They are about equal efficiency. They do not contain mercury, which CFLs do contain.
What we want from a bulb is light, which is measured in lumens, and we have to use power, measured in watts, to get it. CFLs produce about 60-70 lumens per watt. LEDs presently use about the same – 1 watt gets you 60 or 70 lumens of light. LEDs are getting better though – the newest LEDs coming out of the labs are about 90 lumens per watt. These are all better than the old (antique) incandescent bulbs, which only get about 10-15 lumens per watt.
