Reasonable solution for old hole for ceiling lamp?

It is wrong, kind of illegal. If your provider finds out, they should actually cut off the power to you. (In theory, that's how it is, though not in practice)

What is the reason they should cut off the power? What risk do they see with foam sealant?

You should not fill that hole with foam sealant. Find another solution by moving your rail and putting on a proper junction box cover.

I have to ask; for what reason?

An amateur solution that is wrong. May create more problems than it possibly solves.

There you don't have much choice.
Doslock is probably the only approved and sensible option.

I'm completely on board with that. But what is the possible risk?

You don't build connections and conductors and fix all this with foam sealant. One day the connections might need to be redone or troubleshooting might occur, and then everything is embedded in your foam sealant.

So it's a bad solution for practical reasons?

That spray foam burns well is one reason. And that your insurance company likely won't pay any compensation for damage if it can be traced to home-fixed electricity. https://www.viivilla.se/bygg/sakerhet/tacker-forsakringen-egenkopplad-el/

The fact that sealant foam burns well is one reason. And that your insurance company probably won't pay out any compensation for damage if it can be traced back to DIY electricity.

That is the lesser issue.

The major issue is that you are violating electrical installation regulations in a significant and severe manner, on multiple points.
Specifically, chapter 412 on enhanced or double insulation and 513.1 regarding accessibility and 514.2 regarding identification. (all from the electrical installation regulations SS 436 40 00, which everyone installing electricity must follow)

And this leads to your electrical installation not complying with the execution regulations, and a network owner may not connect such an installation to the grid and must disconnect the power if they become aware of such faults.
Now, I have already written that in practice this does not happen with a fault like the one you are contemplating. The cases where it has happened have been much more severe.
But I write this nonetheless because in theory (or if they seriously tighten up and begin following the law to the letter) you can be disconnected and not get power back until an authorized electrical firm has been and fixed the faults and made a new completion notification, and then you also have to pay a reconnection fee.

But anyway, mostly I write like this because it is a very serious error you are thinking of committing, and I don't know how to make you understand it. If you know that by law the electricity supplier should cut the power if it is discovered, maybe you will realize how wrong it is.

In that ceiling box, there were a bunch of connections too.
There is no simple quick fix that would achieve the same result as desired in the first post.

The only way is to chisel out the box and pipes far enough, then install a new box in the desired location and create a track for pipes there, cut and extend the pipes, and then plaster everything back. Finish by fixing all the wiring, shortening what became too long and replacing what became too short.

The only simple alternative is a box lid.

Thank you very much for all the answers!
