Seems strange they would make a MH convertion bulb if you could just plug in a MH. It may work fine you a while but are you getting the potential of the bulb and is it going to last as long. It may just burn out all of a sudden and do you really want to stress your ladies or burn down your house. Try calling phillips or GE and ask the tech support.
