electonic ballast not overdriving??

[Invigor]

yea, it's the f32t8s that i'm trying to overdrive. t8 ballasts will run t12s no problem, but not usually the other way around..I'm guessing the t8s take more voltage to illuminate than t12s. but I am trying to overdrive the t8s :| i'm gonna play around with it some more today, maybe try them in series or something...if you don't hear from me I'm in the hospital with severe electrical burn, luckily the hospital is only 3 blocks away and my gf works there
