[NewCandle] Cold Electricty

[Nick Reiter]

Hi Jones, and all,

The Nichia LEDs Sam Faile and I purchased originally
were direct from Nichia (this was like 1997 or so). 
They were just starting out with marketing here in the
US.  I do not know who their distributors are now.

Overall, my understanding is that any of the modern
"super-bright" blues, greens, or violets are GaN
quantum well.

Now if you want the ultimate poop on all things LED,
get thee to this fellow's site:

http://ledmuseum.home.att.net/ledleft.htm

Tons of links to suppliers, both primary and
surplus...  you'll find many sources for UV LEDs as
well.

Another place that usually has a large assortment of
cheap superbrights in different colors or surplus is
Hosfelt Electronics. Search 'em and see what their
catalog dujour has in it.
