I currently have 6 can lights in my kitchen. I would like to convert one of them to a pendant light. I know there are kits to do that but my question pertains to how to get the pendant light to go on and off separately from the remaining can lights? I would rather not tear out drywall to add a new line if possible. Also, the can lights are currently run by two different switches (at each end of the room, which may complicate matters. Thanks for any advice!
If all of the can lights are on you can install a pendant light that has an independant pull switch. However, this will only work if power is going to all lights currently wired together. If you have a junction box in the ceiling near the can light you are converting: You could bypass that particular can light in the circuit and run new wiring to the new pendant light that has a pull switch.
To have control of this light separately from the others you would need to run a new wire. If the lights are turned off this light would not have power. You could install a smart switch in the fixture j box but this would only allow you to turn on / off when the other lights are on. So to have separate control some new wiring would be needed. Do you have attic access? If you have access above running a new circuit using a smart switch would eliminate the need for tearing out sheetrock. If you don't have access to provide independent functionality of the new light some sheetrock removal would be required.
