The replacement ones I looked at had lower Lumen levels then new 48" LEDs. I bought a single tube LED that has 4200 lumens and a
one that was 3600 lumens. very happy with them. $30 and 25 respectfully.

the downside of the instant replacements is that you are still depending on the ballast in the fixture, even though one isn't really necessary for LED tubes.
They also have ones where you open up the fixture and bypass the ballast. A little more complicated, but then you are just putting the 110v into the LED tube, and not depending on that old ballast to keep working.

Make sure your existing fixtures have electronic ballasts before buying the LED bulbs. All the plug-and-play LED bulbs I've ever seen won't work with old-fashioned (non-electronic) ballasts.

I just replaced a 4' and 8' tubes in shop. I used tubes from keystone direct drive led. Local supply house sold 4' for $8 each and 4000K. They didn't have the 5000k in stock. The guts were removed and one end was rewired based on instructions. Took about 1/2 hour. They were powered from one end only. I wanted ones that didn't depend on ballast, since if the ballast goes bad the LED's won't work. Very happy so far with conversion.
Side note, we had a fixture at church that needed a new ballast and replaced all 4 tubes with LEDs. I made one of the members do all the work and it took about 1 hr including training.

When you are talking K value is that light spectrum or Lumens with a K? K is light spectrum Lumens is the amout of light given off.
I was talking lumens, dont want the issue to get confused.

The ones I saw at Costco are these:

So, they are 4100K and 1650 Lumens per tube. Price was something like $14 for pack of 2. They are a direct replacement without any changes to the fixture, which is attractive. Are these good or low end as far as LED tubes go?

1650 lumens is not much.
