A wall light without an electrician
A plug-in wall sconce hangs on a printed cleat, screwed or taped to the wall, and plugs into a socket you already have. Nothing is cut into the wall.
How it works
A printed cleat fixes to the wall with two screws, or with 3M VHB tape, and the backplate drops onto it: it finds its own centre and is drawn flat against the wall. Inside the backplate a bracket holds an E27 lampholder and a G45 LED bulb; from there a 2 m twisted fabric cord with an in-line switch runs down to an ordinary plug.
Because nothing is wired into the building, there is nothing for an electrician to do: it is installed like a picture and switched like a lamp.
Before you fix it
Choose a spot within reach of a socket for the 2 m cord, and where the switch will hang at hand height.
The paper template in the box is full size. Tape it to the wall with its line level, drill the two marked holes, push in the wall plugs and screw the cleat on with its arrow pointing up. The template shows where the lamp will sit round it.
The screws and plugs in the box are for brick or concrete. Plasterboard needs cavity fixings instead, bought for it.
Rather not drill? Stick the cleat up with 3M VHB double-sided foam tape instead (not in the box), on a smooth, clean, sound surface: firm painted plaster, tile or glass. Not on fresh paint, wallpaper or a textured wall, and not with removable picture strips, which are not made to carry a lamp. Use the template for the position, cover the cleat's whole back with tape, press it hard to the wall for 30 seconds, and wait a day before hanging the lamp. Tape that strong can lift paint when it comes off.
Hold the lamp flat to the wall a little above the cleat and slide it down until it drops into place. To take it down, lift it about 6 mm and draw it away from the wall.
Changing the bulb
The glowing face is held to the backplate by magnets. Lift it off, change the bulb for another G45 LED, and it clicks back.
