Wiring wall lights which usually adds an attractive feature to a room requires two main steps to install, which are, deciding exactly where you want to place the wall light.
Mostly they can be placed on each side of the chimney and it should be noted that for a demystified work wires can be fed from the floor (if not solid) for cases where decorative coving are above where you required wall lights.
Back box of the wall lights
Secondly, appropriately mark and fit the back box of the wall lights. Plaster the ceiling and get rid of floor boards directly above where the wires are going to be feed. Drill a hole through the ceiling most appropriate for feeding the wire down to the back box.
Wiring wall light is much advantageous since independent switch is much far cheaper and most less messy for it allows good lighting where lighting is accessed from various switches.
