M80 ballasts are pretty much gone. Aqua medic was one of the last ones yo make it But they discontinued that ballast a while back. Your best bet is to find a used galaxy or lumatek adjustable ballast that has the hqi or "turbo" setting and use that. That just over drives the bulb to roughly 274w which is what a 250w radium bulb is
Hamilton still sells magnetic ballasts. Are they adequate?
