Which way do the joists run? You might get away just fishing a wire through a hole where you want the new light. If the joists run the wrong way then you need to open up enough of a channel to get a drill in and drill through the joists or find existing holes etc. An electrician would be looking at where the feed comes from and maybe using it to fish through a wire to get it where they want it.
I'm pondering adding another light in my hallway, preferably to be controlled by the light switch which controls the existing light (it's the same hallway, I can't think of any circumstance when you'd want one but not the other on).
It's a flat roof above so I have no access from the top.
I assume the process is to put a narrow channel in the plaster/board from the existing light fixture to the new one, wire a spur into the existing fixture down to where I want the new one, add the light and then somehow patch over the channel.
Does this sound sensible? Am I missing something that is likely to electrocute everyone in the neighbourhood, set the house on fire, result in the apocalypse, make it look a bit shit?
