On Hamilton's website they say you can't run Radiums on the M58 ballast which is kind of confusing. Electronic ballasts aren't the proper ballast to run Radiums, but it still works (just looks more blue) and many people run them this way. So I'm wondering if the M58 works, just not to spec. I'm curious because if I were to buy this fixture, 20k Radiums is what I would run.
