I know this ebay link won't be here forever but this is what you need (
http://cgi.ebay.com/New-50-Ultra-Br...9610QQcategoryZ66952QQrdZ1QQcmdZViewItem ). After this link dies, just search on ebay for "Bright White LED" and you'll find all the 10,000 mcd LED's that you can shake a stick at. (And don't ask me why so many folks go around shaking sticks at LED's) Just use the white ones and let your lenses do the coloring.
