Install staircase lighting

Hello everyone,

in a few days we have to order the stair lighting.
We want to use side LED spotlights for every 2nd step.

Most spotlights, however, have a square cutout. How do you get that into the wall (all Poroton)? Do you chisel all of that?

Regards

Well, I would quite simply claim that the visible frame is "square" and the flush-mounted part will definitely fit into a 68mm flush-mounted box. If not, then you are allowed to chip open your wall accordingly.
