250 W equivalent ballast of a M57?

[dogstar74]

Ok, so I understand that an M57 is a fairly standard, and inexpensive ballast to fire a 175 W MH bulb. But what I was wondering, is there an analagous 250W Ballast that is fairly inexpensive? What ANSI number designation should I be researching?

Thank you

I think the 250w are powered by M58 ballasts. I might be mistaken though.
