Hortilux is saying M47(Metal Halide) & S52(HPS) 1000 watt ballasts; which are ANSI rated 1000 watt magnetic ballasts and enclosed fixtures are required. Looks like they are saying 220 volts are required too?

I wouldn't recommend a digital ballast; with one of these expensive puppies...$$$$
Dutch Pimp Reviewed by Dutch Pimp on . Dual Arc Lamps Any one know anything about the Metal Halide and High Pressure Sodium tubes that are combined into one glass. It would seem Iâ??m not losing any of the red or orange just picking up blue to go with it. Just wondering if they would be better for veg and or flowering?? Iâ??m not worried about cost as much as I am about quality and yield. I will replace bulbs when need no matter what they cost me. Two 1000W bulbs will cost me $287, if I get 4 bulbs to switch out it will cost me like $350= 2 Rating: 5
