To the OP, what are you using to control the LEDs? FETs? Spikes? Victors?
Two 2N2222 in the T092 package per channel. Ours are rated for 800mA each, so we have 1.6A of capability. I put in two to handle heat dissipation a little better. The weakest link in our box is the 12V regulator, rated for only 1A.

I'm not 100% sure of the current of each bar for each channel. We may have to bump it up to 2 or 3 voltage regulators, or we could drop the voltage regulator completely because of the fact that the RGB bar is pretty rugged.
