Anyone with a ballast that can fire up a 175W MH bulb?

[Richer]

I think one of my 175W MH bulbs is shot... which would explain why it won't fire up. However, my setup is new, and a faulty ballast can't be ruled out... although that ballast has the ability to fire up the other bulb that I have, so the chances of that are pretty slim. Does anyone have a working 175W ballast that I can test fire this bulb on? I would hate to return the thing, only to find out that I was a doofus.

Thanks!
