I had a ton of 4' florescent lights in my previous house, and the ballasts were dropping left and right after about 25 years in place. I ended up replacing them with the LED's that require rewiring, they were great and way brighter than the old florescent bulbs were. As a bonus, the LED tubes I bought were dimmable, so I could control the light intensity. The rewiring is pretty simple, and I was lucky that I already had the non-shunted tombstones so I didn't have to replace those.
Agreed if you are going to replace the bulbs, it’s time for a full upgrade. Because if the ballast is not failing now, the electric gods will make sure they do soon after.
do it once do it right.
