LED Recessed Spotlight Positioning Proposal

Since I don't think the idea is bad, here are a few more questions about it

These are just the cans for the spots for now.
How do you then do the wiring of the spots to each other?

Doesn't the pouring shift the pipes?

Should the closed pipes be flush after pouring the ceiling or not visible at all?

The cables are, of course, laid simply from box to box for each lighting circuit. As already mentioned, the better solution would be to install cable glands on the DIY boxes. These are, firstly, sealed and secondly provide strain relief. The cable is looped inside the box at the edge so that it is not damaged later by the hole saw. The boxes should not be visible, just like the Hallo X P boxes from Kaiser that are installed at the factory, which also disappear. If the boxes shift onto the precast slab when pouring the in-situ concrete, they have been insufficiently fixed. But what could really happen? Fix with silicone, adhesive, etc. and additionally have the steel mesh placed as close as possible to the box. Besides, there is quite a bit of leeway. The box has a diameter of 125-150mm and the hole only gets 60-80mm.

The wiring is, by the way, the same as with the sockets, which are installed at the factory.

For you as an electrician, that is logical... but for the average person, this is usually the first ceiling.

Close the sawn pieces on one side with the lid and glue them. Drill 2 holes for the cable guides, ideally insert cable glands into the holes.

I have to ask again. When I see this with Kaiser boxes, the holes go out sideways, right? And then empty conduits are connected where the cables lie, or is it installed without conduits and only with cable glands? Or does it depend on whether high-voltage or low-voltage lights are used?

Hello,
we are also very interested in this procedure.
But our question is, how do we attach the recessed lights or the frames in the hole afterwards???
That means, there are these "clips" on the frame of the lights that have to grip the ceiling from "behind." How is that supposed to work if a 6cm filigree ceiling has to be bridged???
Elektro1, can you help with that?
Best regards

Hello,

in the meantime, I have carried out the entire procedure myself and must admit a small modification.
The 68 mm holes should be drilled immediately and not after the concrete has been fully poured.

In my case, the precast concrete slab is 5 cm thick, and I also have the clamps you mentioned; they do not open completely but enough to hold the recessed spotlight.
For the desired mounting ring, care should be taken that the spring is not a weak little spring (sometimes cheap Chinese goods).

Cheers
