You might want to contact LEDTRONICS. www.ledtronics.com They have a tech department that will be able to take care of both answering your questions and supplying the leds directly. I cought some RGB leds from them not too long ago and was very pleased with the help and service Eddie, kc4awz -- http://www.piclist.com hint: The PICList is archived three different ways.
