Questions about LED luminaire

Hello, can you help me with these questions ?:
-In the fluorescent lampholders I see that there are 4 holes through which to put the cables, two on each side:

Why are there 4? It doesn't matter where the cables connect whenever they are on different sides?
-Do LED tubes have polarity? If it connected around it would it break down?
-To fix the luminaire to the ceiling apart from those with 2 nuts with which it is fixed to the ceiling is it advisable to put something else? I have the "no more nails" glue out there, do I put any of that on it or not?

To hang the fuorescent of a center box, or from the roof itself, a support called a crossbar comes in Argentina, which is a sheet with holes 75 mm away (coincides with the holes of an octagonal) where a stud can be screwed or 1/4 "W screw.
This support is central and holds any type of luminaire in a safe way, since it bolts perfectly.
Just a precaution, buy them only in electricity houses, do not look for crossbars anywhere (to avoid surprises)

I know that about the crossbar, I have removed the luminaire to replace it with a LED and now I will put it back on the crossbar where it was.
My question is if I have the "no more nails" glue out there, I can put something on it. I ask you about my insecurity because it is the first time I change one and the installation is over 30 years old. If you say that only with the nuts is it safe enough to hold another 10 years then it would not be necessary.

Well, I asked because theoretically that glue is intended as a nail substitute and can withstand a lot of weight:

I suppose they are a little paranoia of mine, only with the nuts should I endure if it has always been that way.

Hello
although there are 4 holes, there are no 4 contacts there are only two with 2 inputs each to use either one or the other. They come this way to connect several lamps in parallel (garland system) even though this system is now prohibited
The lamps do not have polarity with respect to the alternating current, the polarity of the led is set by the internal source
not only is it not necessary but it is not advisable to place glues, only the predefined fixing system is sufficient

Three reasons:
1- Because not all adhesives meet the dielectric and flame retardant properties, this is relative since it depends on which glue you use
2- because when gluing and not anchoring while the element is suspended, there will be a high risk that the glue or the surface where it was stuck will fail and fall
3- because in case of requiring maintenance it is difficult to disarm, running risks of damaging the different parts
