Set up the lights today, boy is it a bitch to find studs! At least things are moving along. I am very suprised by the amount of noise created by the ballast, you can hear a slight hum from outside the room, and I am a bit concerned about that. Right now its just sitting on the floor, I wouldn't imagine you can do much besides possibly mount it on a wall, which might actually create more noise. What do you guys do to combat this if anything
