I just saw an announcement about these in the January issue of 
EE Product News. Reproduced without permission:

"For years, the industry has awaited the advent of a blue LED.  These
unique silicon emitters are now available at prices between $12 and
$15 each. Operating at 470 nanometer wavelengths, 100,000-hour LEDs
come in both single- and multi-chip configurations.  LEDTRONICS, 4009
Pacific Coast Highway, Torrance, CA 90505. (213) 549-9995"

Hope this helps.
