Why is energy consumption not related to our choice in lighting? Most LED advertisements mention energy consumption compared to other bulbs. Based on unclear comparisons.

I didn't realize printed text had a 'tone.' ((One cannot type emotion))

Nonetheless, I'll not respond, anymore, to this thread.

A concrete ceiling, so I just as soon replace the long one with a 4' T8 fluorescent fixture, I don't want LED. So googling around I found an outfit called 'American Fluorescent, assembled in USA. I had gone to home depot and the lithonia made in Mexico fixture got poor reviews on amazon.

The installation instructions say that buildings before 1985 have wire rated at 60C, and this fixture needs feed wire rated at 90C. So how do I know what I have ? How much does it matter ?

I've wired outlets, ceiling fans, odds and ends. So I'm not clueless about it, and feel competent to do a simple thing like this. Any info would be appreciated.

OK so here's the deal, the fixture mfg. Has done what is called derate or adjust for
temperature, the temperature near the ballast may be high causing the wire to get hot as well
The hotter the wire the less ampacity it can carry, so the mfg has specified 90° wire to account for the increased temp., The increased temp can also break down the insulation, this is the biggest reason to derate.
All you have to do is put the old wire in a junction box and take a short piece of new wire to the fixtures, 1 4x4 metal box, blank plate and 2 Romex connectors and some wire nuts, and your good to go.
