I want to install 4 LED recessed lights in my living room.
No ceiling lighting currently exists though there is an existing wall switch that was decommissioned by the previous owners that I plan to re-purpose to control the new lighting.
The wire powering the existing switch is the standard 2-wire (plus ground). Do I need to use 3-wire from the switch to the lights? I heard that any new wiring for ceiling fixtures should be 3-wire according to code, but I haven't been able to confirm if that's true.
Aside from future-proofing, my lighting plans should not require 3-wire.
Any advice is appreciated. Thanks.
