Hey WW,

Almost any induction load is more efficent at 220v versus 110v, and that includes magnetic ballasts. Keep in mind that most of the efficency gained is durring start up, decreaseing the intial surge amperage.

oldmac Reviewed by oldmac on . Galaxy Digital Ballast feedback??? Looking at investing in the multi wattage digital ballasts. So far, I think the Galaxy 1000, HPS/MH, 400-600-1000 watt settings, can run bulbs at full power or reduced power (does that make bulb last longer?), and supposedly less heat. Not sure which puts out how much, but 1000 watt bulb puts out a lot of heat. Anyway I like the ability to use at any wattage and to use either HPS or MH. With some of my experimenting I need more flexibility. So, since it is a $400 investment, is it Rating: 5
