Thenks for the prompt replies so far guys. The specs on the LEds are 150mA Peak forward current and 30mA continous. Its for a movie prop and something like a mini Tunnel that would have over a thousand LEDs in the inside wall. Basically all I want it to do is be able to light up the whole tunnel in one colour, at other times the led would move in a pattern as though the people inside are moving forward at a tremendous speed or spinnning around..etc. You get the picture !! Green screen stuff. I don't understand yet, how to drive all the LEDs to full brightness and control them. Any help or suggestions is greatly appreciciated.
