We just bought a house and I have a light in our screen porch (aka Florida room). It has a light in the center of the ceiling that I can't identify its light switch.
Thinking it might be the bulb, I pulled the globe down and instead used a non-contact voltage detector after flipping each switch even remotely near it (and some further away thinking it may be daisy chained off of another light fixture). The ceiling isn't going to be easy to get into to track the wires, but I'm afraid that's my only option.
Any hints or tricks for tracking down the power source of a light fixture?
