I would like to install 4 recessed lights in a bedroom. Currently we have 2 light switches, 1 light switch operated the light & the other operated the fan. We have removed the fan and want to use the wires and switch that operated the fan to run the 4 recessed lights. How can we do this? What do we need? And the wiring would have to be run through sub floors with ceiling joists. Any tips on how to move the wire through the ceiling joist would help also. Thank you for your help
