On the right track?

Join the CF seekers club. As the CF can only drive 2 Amps the 3 dice will only get 650ma each. That's why most drive 2 dice with it and 2 for clash.

Ok I'll look into that. Thank you for your help and patience.

As far as i can see it you have 2 choices

1) get a fat as driver, this one should do the job and hopefully fit.

or

2) wire the dice in series, red and green (to get yellow) blue and white (for your flash on clash) that way you only need 2000mA from your supply and your voltage drop is only 7.2(or what ever battery volt you go for) down to the total V of the dice (around 6V). So you can almost get away with a 1w resistors. Wiring the the blue and the white for the flash on clash will give you that extra brightness you were after.

This is a helpful tool, when planing this stuff out

Hope that helps.
