I have a home office, which currently has a couple of wall lights (controlled by switches on the wall, so part of the normal lighting circuit).
I'd like to install some wall-supported shelving, and the lights are in the way. I'd also quite like to have some lighting (possibly LED strips) under the lowest shelf to light the desk.
It seems to me that I should be able to just extend the wiring from the wall lights down the wall, and connect the under-desk lighting that way, so that it continues to be operated from the wall switches.
My question is: what's the correct way of going about this? I expect the light fittings will just have some wire coming out of the wall - should I install a backbox and some sort of front panel (with a socket, or just a fuse?) Should I angle-grind a channel in the wall and extend the wire, and if so how should I terminate it then? Or can I just chocbox the wire outside the wall and fill it in a bit?
