Wow. 2000 watts? No one has mentioned the obvious... how would you power the thing in a home darkroom? The normal 15 amp breaker in a North American home would be too small, even it this behemoth was on a dedicated circuit. You would need to go to a 20 amp breaker as a minimum. Or perhaps this thing wants 600 volt three phase ;-) ... and an air conditioner to keep the darkroom bearable! Brock
