The LED tubes, are the bluish white ones. Their light is ugly, the T5s looks much better.

The fluorescent are 2700K i think, as they looked too warm to me to be 3000K. Many of them dimmed btw, and I don't know if this either because of plastic erosion, loss of mercury or impurities inside the tubes.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

It is rare that the phosphors of fluorescent lamps, fades to such a low level. I've never seen fluorescent lamps that their phosphors faded so much (There are several that aren't visible here, that faded so much, that they can be considered EOL, even if they are still works).
Triphosphors should be more immune to high temperature and loading, which is the reasons for using them in CFLs and long T5s.

The LEDs look totally out of place, they could have atleast used some that were the same color.

Those lamps that are getting dim could be going mercury starved too...

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

The t5 always go dim when a lot of hours turn brownish. Led I gess is OK in this application but t8 or t12 or t17 would look cool here if not recessed

T12/ t17 there's a reason they made heavy magnetic ballasts
