Instead of changing the whole fixture would/could it be easier/cheaper to just change the tombstones and the ballast and leave the same fixture there. Or do I need to take whole unit down and replace it with a T8 fixture?
Make sure the LED tubes are direct wire not "ballast compatible" or "plug and play". Some are listed as direct wire and ballast compatible, that will work also. I prefer the LEDs that are wired to both ends of the tube, it allows the use of shunted or un-shunted tombstones. Single end wired LEDs require un-shunted tombstones.
