if its a new ballast you've bought then it will be HPS/MH compatable. if its more than 6 months old it might not be. just try a bulb and watch it for a day or two and if does'nt over heat or burn your house down your O.K. hahaha. be carefull

There should be an ANSI code on the label.. if it starts with an S than it is HPS bulb and if it starts with an M then it is metal halide.
