the only difference between hps and mh is hps hs the addition of a ignitor where a mh bulb has ignitor built into bulb

right but the new balast they make except either bulbs ? cause i know on the old ballast u either use mh or hps or u get a conversion bulb....so my question is do they even make a hps or mh ballast like they use to or are the bulbs all inner changable now?......edit ....im talking about those big baulky white ballast that use to hum louder than your radio....lol i dont see them in stores anymore those only ran one bulb or conversion

no they dont make all ballast like that just grow ballast i use streetlights
a switchable ballast like u refer to is just a reg ballast and a switch that when u flip it to hps has a ignitor they still make just hps ballast and mh ballast
but the safest buy is a hps ballast then u can run both but if u get a mh u got to add ignitor or conv bulb hope i made sense lol
