I have this scenario, two troughs set up on each side of a room with a 1.5ft path down the center. two lights will be required to cover a 4x10x8 area each. the lights will be on a light mover of course. would a 1k on each side be more effective/and efficient than a 600 in the situation? Power is not an issue as well. I am running a 240v dedicated circuit for the lights so I can put the fans and whatnot on the existing circuit and not overload.
