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 -jim bo -------- Jim Skrentny University of Wisconsin Computer Systems Lab office 608-263-7463 (afternoons), home 608-251-5683 USENET: ...!{allegra,heurikon,ihnp4,seismo,ucbvax}!uwvax!skrentny ARPA INTERNET: skrentny@cs.wisc.edu
