This https://www.amazon.com/Wraparound-T...654714203&sprefix=led+fix,aps,88&sr=8-26&th=1 gives 5500 Lumens at 40 watts or 11,000 lumens at 80 watts.Just to provide a little reference on why I wasn't so keen on LED tubes. The top link are the LED "plug & play" bulbs I installed in my other house. They only provided 1,800 lumens on 18 watts each.
The bottom link are the T-8 tubes I have presently installed in my new fluorescent fixtures. They're standard GE T-8 tubes, that provive 2,900 lumens each on 32 watts each. These also offer a much brighter, blue white light. (6,500K vs. 5,000K for the LED's).
Multiplying this out times 4 bulbs, the fluorescents are giving me a total of 11,600 lumens, with a total consumption of 128 watts. Compared to the LED's with only 7,200 lumens at 72 watts.
So while you are "saving" 56 watts, you're doing it with 4,400 less lumens of light. That's a substantial difference. I could tell immediately when I swapped them out in my other place. The entire kitchen was noticeably darker.
I'm sure someone somewhere either makes a brighter LED, or else soon will. (This stuff is always improving). But as Panda Bear mentioned, all of this crap is Chi-Com these days. And many of these LED's don't last anywhere near their claimed hours or years of life expectancy. So after going through all this, you end up with 6 of one and a half dozen of the other.
In a nutshell, while these LED tubes have come a long way, and are getting cheaper, I just didn't see anything to gain by going with them again. Perhaps in years to come they will offer a substantial improvement, (like many of the screw in LED's now do when compared to the old incandescent and CFL bulbs of just a few decades ago).

If you're stuck with a built in fixture, then you're stuck with retrofit bulbs. But if you can change out the fixture, that's the way to go.
