i have used in the past a pc power supply case (400 watt mh), and a large junction box. (1kw hps). no problems with either and i still run both of the lights. the mh has the transformer on the outside of the case. i just put a layer of fibreglass cloth (no resin) between it and the metal of the case.
wesley willis Reviewed by wesley willis on . Ballast Container? You guys know of anything that would work well to hold a ballast? I have the biggest project box that Radio shack sells and it's not tall enough to put the lid on and barely has room for the capacitor/igniter. It seems impossible to find a reasonably sized enclosure anywhere, but maybe I just don't know what to look for. Rating: 5
