there's nothing wrong with using a mh bulb off a hps ballast, other than shorter bulb life. vice versa won't light, as the hps bulb needs the ignitor to light. the ingnitor is the only difference between the two.Its making that noise because you are using a MH bulb in a HPS ballast.

He's using a MH conversion bulb designed to work in a HPS ballast.Its making that noise because you are using a MH bulb in a HPS ballast.
But they do need to cool down for 15 minutes before they work again.
