are your lights going above the deck or underneath? My deck the lights are underneath and i can fit 2 500w halos, side by side, with about a 3 inches gap. also are you going to cover the deck with wood or aluminum?
Was wondering if your talking about supports that go vertically to get the platform in the air, or the one ones that run horizontally under the platform that you stand on.The lights are going under the deck whic is going to be expanded aluminum. Not sure about the vertical vs horizontal questions it is 1 inch square tubing.
