Led Strobe lights

[Aaron moat]

I am curently building some led strobe lights. I have build the lights and have an old 3 chanel DMX which i want o use to controll the lights. the Curcute board is 6v and i need to make some electronic switches for it. i have tryed relays but they don't deal with the speed of the lights. What do i need to use to swich the chanels? Thanks
