We are considering installing recessed lighting on a ceiling that has another floor above it. The ceiling currently has no light fixtures except a central ceiling fan.
I can't access the ceiling from the floor above. I'd like to avoid having to rip down the entire ceiling to get at the joists and run wires perpendicular to them.
No, I don't have any other "special access" like around the edges of the ceiling. I will have to do everything from underneath it, while inside the room.
What are some good tools and methods for running wires from one recessed lighting fixture to the next? Fishing from one fixture to another in the same joist bay seems pretty straightforward, but how do I get wiring through the joists across multiple bays? The ceilings are higher than a normal room, so it's likely that I will have to run through 3 or 4 bays between lighting fixtures.
I'd also appreciate any advice on things to watch out for. I already know that there is no ducting or piping in the ceiling, but there may be wiring. How do I ensure that I don't run into existing wiring?
