    Did you know that Christmas lights using LEDs are now available? They're expensive and are supposed to last forever, and use very little electricity.

    I also see that LED lights are available for other uses (e.g. car signal lights and lighting in general)

    Does anyone have any experience with these?

    I have LED snowflake lights under the gold drape for my nativity just to give the area a tiny bit of light at night... They're cool as hell.. (with a better picture taker).. They were $25 for 35 when they first came out, which is what I paid.. They might be a tiny bit cheaper now, but not much...

    Maybe I'm telling you something you already know, but LED stands for "light emitting diode". Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescent bulbs, they don't have a filament that will burn out, and they don't get especially hot. They are illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor.

    Thanks for the info.... I got interested in them the plant I work at decided to change all the "Exit" signs over from using lightbulbs to LEDs. Apparently, they saved money on the electricity because LEDs use about 20% or less electricity but give off the same amount of light. Plus, they have a very long life (over 100,000 hours --- or about 11 years).

    I also noticed that many traffic signals are being converted over here in my hometown. The reasons are the same (cost and low maintenance). I once read that major cities that have converted over are realizing a cost savings of millions of dollars in the electric bills.

    Now, trucks and cars are using them in their signal lights, too....

    My guess is that the regular light bulb's days are numbered. I'll guess within 10 years or so, the technology will become cheap enough to make it worth converting over...
