One of the fluorscent tubes is dim

Hello all - I have a tube light fixture (2.5 years old) in the garage and as you can see in the below picture, one of the bulbs is dim (just dim, no flickering or any other issue). I tried rotating the bulbs, swapping them and replacing one of them with an LED bulb as well - there is no issue with the bulbs they are both working fine. Looks like the fixture has some issue? Please let me know how I can fix this

That lower tube is shot. The ends look burned.
You cannot interchange LED and fluorescent tubes.

Just put in two LED tubes and be done with the problem.
Also.... be careful which tubes you buy. Some require the ballast be removed.
It should be explained on the package. Ultimately removing the ballast and rewiring the tube sockets will yield the best results and lowest energy use.

I went ahead and got another LED tube light to replace the fluorescent one. But even with the two LED bulbs, one of them is still dim. Tried swapping them, adjusting their positions etc. but same issue. Is there anything else I can do other than replacing the entire fixture?

You should have gotten the type that required the ballasts to be removed.

You had a ballast issue and still do which is why they are not working with the new LED bulbs.

In all honesty the bulbs that work with ballasts are not much better than the old fluorescent bulbs!

Cannot tell if these LEDs will work without a ballast.

So read the fine print on the package many can be used with or without.
Since they work with a ballast I assume they have Neutral at one end and Lin at the other.
Note that some get 120 at just one end.
If all OK rewire the fixture removing the ballast.

When I update a fixture to LEDs I always remove the ballast.
Why keep a part that does nothing and can cause problems!!!
