Hello all, My question is this:Can I run a 250 watt light from a 400 watt digital dimmable ballast on 50 or 75% ?
Very true.IF , the 400 digital ballast has a selectable 250 HPS mode , then yes, but not all 400 digital ballasts are made the same. Some 400 dimmable ballasts are meant only for 400 watt bulbs. This particular 400 digital ballast will run a 250 watt HPS bulb >
