if its a magnetic ballast , you cant go wrong. and if it was an hps it will run a mh with no switch. the switch is a gimmick. a rebuilt magnetic ballast will out perform a brand new digital all day.I just found and purchased a 400 watt mh that comes with a ballast and the bulb for $131.57
if its magnetic you might need a 5 dollar part in 20 years , if its a digital , you'll need 10 new ballasts in that time.
like i said whether its digital or mag , all hps ballasts will run a mh bulb with NO ill affects. no switch needed , but will not work the other way around.
so for 10 more bucks you can tell them to send you the hps instead. ?
