That's what I need to replace all the ordinary ones with. The point is common t5s suck unless you specify parraell. Not like t8s which are probably not series t5s seem to be more like old t12s what a giant step back wards
T5 and T8 ballast both can be ordered parallel wired or series wired, what I have run into is one manufacture who put both in one fixture, a 4 lamp parallel wired with a 2 lamp series wired in a 6x high bay:rant: I know there was a shortage of ballast at one time but I think this was uncalled for.
But anytime I re-ballast a fixture I order parallel ballast and since most T5 4 lamp ballast are nothing more then 2x 2 lamp ballast in one can, I just replace the 4 lamp ballast with 2x 2 lamp ballast, every time one side will fail and it seems a waste to replace a whole ballast with one side still good, I move the 4 lamp ballast to the single 2 lamp mounting place (input power is separate and connected by jumpers on a 4 lamp T5 ballast) and use the good side, and put the 2 good 2 lamp ballast back in the place of the 4 lamp, most fixtures have the mounting for both types of ballast.
Just make sure when you order fixtures or replacement ballast to ask for parallel ballast, it doesn't take much to rewire a fixture from series to parallel.
I would still take a T5 over a T8 any day, more lumen's per watt.
