Which MH Ballast?

[nickh06]

I am looking into running some MH's on my new tank build. Can someone recommend a good ballast for the 250w Radium bulbs. I know they should be pushed with M80 ballasts but wanted to hear experiences from anyone running them with electronic ballasts. Thanks

Hamilton m80's.. about the last ones being sold. Unless you find some used bluewave7's

Ballast choice depends on the bulb you want. For radiums you want a ballast that will overdrive the bulbs. Magnetics are usually the best for that like the M80 mentioned above.
