Is it possible to run two 175 watt metal halide bulbs on one 400 watt ballast?
No, HID (high intensity discharge) lamps have to be matched to the ballast exactly, by type and wattage. Only a 400 watt metal halide bulb will work on a 400 watt MH ballast. If you have 175 watt bulbs you will need a 175 watt ballast for each.
