(Can't guarantee these are the absolute correct size, but they look to be...you should double-check yourself.)
These LEDs are plug-n-play, meaning they are designed to work with the ballasts in those fixtures. If you were to replace all the fixtures with new LED fixtures, you wouldn't use these bulbs.
You should do the math to figure out what's the most economical way to go.
Replacing these fixtures might be a bit more of a pain than say, replacing overhead fluorescent fixtures, which is pretty simple and you won't have your head cocked at a weird angle the entire time.
