I just bought a 2-pack box of led direct replacement for the old bulbs for 17.99 at Costco. No mods needed, plug and play.
The price is finally getting competitive on these
What I don't like about the "direct" bulbs is that you are leaving the ballast on the table which can AND DO fail. Then what? You get to spend more money on a replacement ballast.
If I was replacing tubes, I'd want to rewire (which takes only seconds IE "a couple of minutes" ) and dump the ballast
