Right Metal Halide for an electronic ballast?

I need to get a metal halide that will run on my hps/mh electronic ballast. However there seem to be 3 types of metal halide bulbs to buy, First is the regular MH, second is the MH conversion bulb, and third is the MH Electronic start bulb. Which of these will work for my electronic ballast?

When I was little, I had a cat. I named him whiskers. Hope that helps, keep growing, my friend.

MH conversion bulbs allow you to use said MH bulb on magnetic HPS ballasts. Which is useless.

Get the pulse start. Pros to pulse starts are longer life, better cold starting, shorter warmup times.
