This is an upgrade of the Lersta lamp from IKEA. Promising a clean and organized look, this wall mount comes with an included cable management system.
The cable clips are available on either the left or right side of the main component and can be customized to suit your exact needs.
The included lamp base is easy to install using the included mounting hardware. Simply screw the included screws into the wall to hold the bracket to the wall, but leave enough space for the cable to slide into the cable routing channels. Remove the lamp base and slide the tube through the parts until the bottom of the tube is firmly seated in the base. Now make sure to slide the cable into the cable routing channels and then fully tighten the screws.
To enhance this setup even more, you can print this switch holder and use it to mount the dimmer on the wall. That way it will be in a fixed place and the cables will look nicer than they would if the switch was just hanging around haphazardly.
