Connecting LED ceiling lamp - several cables hanging from the ceiling

As far as I am concerned, the pragmatist should come and not the electrician. The question only implied that basic knowledge on the subject is not present. And I repeat once again: If it is a lamp with a metal housing and the old circuit described above, which has no separate grounding, then there are situations where it is not the lamp that lights up, but the person who wants to screw in a light bulb.

I do a lot, but I have a tremendous respect for electricity...

Thank you very much for all the answers. I will report back :)

If you still can...

A doctor just died locally because he touched an electrified door in his practice after an electrician presumably botched the connection. (One of the arriving firefighters also had to be resuscitated. 8 children behind a second electrified door were warned in time!)

Since I read that in the media, I see our motor lock in a completely different light... ^^

Thank you for the response and warning :)
