The 120vac 4' tubes require eliminating the ballast? Is there a preferred source of 4 tube fixtures?
Yes, the 4’ tubes require that you bypass the ballast, at least all the ones that I’ve seen. When I retrofitted my shop lights, I also had to replace the tombstones with non-shunted versions. Not sure of a freferred source, they’re pretty universally available.
I purchased replacement LED 4' tubes at Costco and didn't have to do anything but change out the tubes. It has been 2 years now and they still work fine.
