A while back somebody asked about LED replacements for incandescent bulbs
they supposedly have 100,000-hour life. The are not subject to failure from
shock, vibration or cold. Also the LED's operate at lower temps. and less
current. I have only read an ad in a trade magazine and know nothing else
about them. This is the info. in the ad.

The April issue of wired had an article about blue LEDs. Aparently, some company in Japan just
recently succeeded in making blue LEDs that put out any amount of light and lasted longer than a
couple miliseconds. They mentioned that this made white light from and LED source possible for the
first time. Of course you need more than one (although they might be able to integrate several different
wavelength LEDs in real close proxcimity on a wafer and put them out in a single package). Apparently,
LEDs are considerably more efficient than incandecent bulbs and last much longer than even compact
flourecents. Sounds great-- I want one in my mag light.
