Replacing fluorescent 2x4 fixtures with LED...which approach?

[clay]

I have just ordered a 4 pack of 4' tubes as drop in replacements in one of the fixtures. They say they're compatible with some newer ballasts but will work with ballast bypassed. I'll just bypass the ballast, since I'm guessing whatever I've got is not new enough to be described as a "newer" ballast.

I'm going to see how this first set looks, and then decide how to proceed with the rest of the lights. We might actually want to go with different approaches for different fixtures, depending on the type of light we want in each area.

Thanks for all your input!
