One manufacturer of "kilo-bright" LED's is AND, distributed by Newark. Note
that the angle of view is much restricted compared to standard LED's. Here
are some specs (Newark catalog 109, page 169):
		 red, clear T-1 3/4 package, theta = +/- 4 degrees
		 1000 mcd @ 20 ma, AND150AR, newark part 87F348, $2.55 ea
		 2000 mcd @ 20 ma, AND150BR, newark part 87F349, $2.73 ea
		 3000 mcd @ 20 ma, AND150CR, newark part 87F350, $5.50 ea
		 red, clear T-1 3/4 package, theta = +/- 20 degrees
		 300 mcd @ 20 ma, AND120AR, newark part 87F351, $2.55 ea
		 600 mcd @ 20 ma, AND120BR, newark part 87F352, $2.73 ea
		 900 mcd @ 20 ma, AND120CR, newark part 87F353, $5.50 ea
