As my 4 foot T12 fluorescent lights in my shoplights fail, can I replace
them with 4' T8 tubes? These shoplights all seem to have electronic
ballasts, consisting of a small, sealed plastic package about 2"x2"x1/2".

Thanks

An electronic ballast isn't a guaranteed universal lamp ballast, otherwise,
it would most likely have T-8s in them. Double check the ballast to
determine if it's T-8 compatible. If not, then you'll need a T-8 ballast.
