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

Walter

** No, the 32 watt T8 lamps use a different ballast. Those really cheap
shop lights with the integral ballast, aren't designed for ballast
replacement
As long as they have the sockets and wires, an electronic ballast can be
added. Though, it might be cheaper to buy a whole fixture than a ballast.
