Electrical connection in the bathroom or for a mirror cabinet

No; a normal one is round. This one is ship-shaped; with a lid and cable entry inside

I guess he means the little boat.

I told you, wandauslassdose

One question about this ship-shaped wall outlet box: do I also use this for wall lights indoors and outdoors, or is a normal flush-mounted box sufficient for wall lights?

Hmm, that is up to you. Basically, it’s the same thing. Only the form is different and accordingly the preparation.
