I recently was looking for bright LED's to stick on my rollerskates, and the
only really bright ones I could find were red.  This got me wondering what
the brightest standard-size one element LED's of various colors are.  There's
also gotta be some physical reason why red ones are easiest to make
brightest.

The red ones I got were from Radio Schmack, and put out 2000 mcd.

Also, what's the easiest way to blink a high-current LED at say 2-10 Hz?
I've heard there's some way to do it with a 555 timer, but electronics isn't
my strong point.  Blinking LED's (that have the driver built in) seem to be
a lot dimmer than non-blinking ones.
