Two ceiling lights on one connection

I believe I remember that unlike your "earlier," these flat cables are no longer permitted in plaster. Doesn't matter if no one checks, but there must be a reason..

Correct, it probably has to do with the fact that the cable or the rubber coating can become brittle (whenever). But for the OP's household use, it's completely sufficient.

Or are you trying to tell me now that the plasterer laid that thing down perfectly smooth?

Yes, we only had it sanded once more in the living room. The light hits the ceiling so damn badly there that it had to be more than smooth and straight.
In the rest of the ceilings (about 150 sqm), at most a blemish from the plasterer was removed. The guys really aimed to deliver the ceilings ready for painting.

You write it as if it were easier that way

I can't say whether it's easier – in any case, it's simple and not a big effort.

Says the one who hasn't done it himself. But let's leave it at that... I have plastered ceilings in Q4 and walls (concrete walls) as well. And especially ceilings are a nightmare for every plasterer - the plasterers didn't say anything about that because it wasn't their area.

That’s why we have an exposed beam ceiling ... for that it’s a job for the painter *harhar*

All done correctly

I actually wanted to slot into our filigree ceiling first. But then I simply built a relatively shallow box out of MDF and painted it with wall paint. Sounds ugly but we like the result. The box has the advantage that, besides the wiring, you can also put a transformer for LED strips inside, which indirectly illuminate the box lid and the ceiling. The additional light really makes a difference since we only have lamps hanging underneath that emit a fairly small light cone.
