Fitting a wall light: fixing, wiring and connection

A wall light brings warm accent lighting, ideal in a hallway, bedroom, staircase or above a sofa. Its installation requires two skills: fixing to the wall and the electrical connection. Whether you start from an existing junction box or a simple outgoing wire, this guide explains how to fit a wall light safely and achieve a clean, professional result.

The necessary tools

Choosing the height and location

The wall light is generally fitted between 1.80 m and 2.20 m from the floor in passage rooms, and between 1.50 m and 1.70 m above a headboard. On a staircase, fix it at eye height to avoid any risk of impact. Before drilling, check with a metal or voltage detector that no electrical cable or pipe is in the area. Mark the position of the fixing holes using the template supplied with the wall light, checking the horizontality with the spirit level.

Drilling and preparing the wall

  1. Switch off the circuit breaker for the relevant circuit and check the absence of voltage on the outgoing wires with a non-contact tester
  2. Drill the fixing holes: use a 6 mm masonry bit for standard anchors, or a hole saw to install a recessed box in plasterboard
  3. Insert the anchors and screw on the fixing bracket, adjusting the horizontality with the spirit level
  4. Bring the supply cable out through the opening of the bracket (about 15 to 20 cm of wire protruding)

Connecting the wall light

  1. Strip the conductors to 8 to 10 mm with the wire stripper
  2. Connect the live wire (red, brown or black) to the L terminal of the wall light
  3. Connect the neutral (blue) to the N terminal and the earth (yellow-green) to the earth terminal, if the wall light is fitted with one
  4. Use Wago connectors or a connector block to extend wires that are too short, placing them in a protective box
  5. Check each connection by pulling gently on the wires, then refit the body of the wall light onto its bracket
  6. Restore the power and test the lighting by operating the switch
Tip: For a metal or conductive wall light, the earth connection is mandatory: always connect the yellow-green wire to the earth terminal block. Without an earth wire in your wall, do not fit a metal wall light, or call in an electrician to create a compliant earthing.

Variant: connecting the wall light to a recessed box

If your wall is drywall and you start from a recessed box, the method remains identical: the wires arrive through the box, you connect them to the wall light's terminals, then you screw the wall light over the box. Make sure the wall light completely covers the box for a clean result and correct protection of the connections. If the box is bigger than the wall light's bracket, use a larger diameter mounting plate or a suitable wall cover.

Choosing the bulb and the lighting atmosphere

The wall light serves to create an atmosphere: prefer a warm light (2700 to 3000 K) for a living room or bedroom, and a more neutral light (3000 to 4000 K) in a hallway or entrance. The power varies according to the effect sought: 2 to 4 W in LED is often enough for a decorative wall light, while a reading light will need 6 to 8 W. Check the wall light's base (E14, E27, GU10 or integrated LED) before buying your bulbs. For accent lighting on a painting or a plant, aim the wall light at the object and use a directional beam bulb. Finally, if you install several wall lights, make sure they are fed by the same circuit so they can be controlled together.

The mistakes to avoid

Fitting a wall light is within reach of a careful DIYer: a few holes, correct wiring and a solid fixing are enough to get durable decorative lighting. In case of doubt about the existing circuit, especially in the absence of an earth wire or standard compliance, a professional electrician will guarantee the compliance of your installation. Once your wall light is fitted, all that remains is to enjoy the atmosphere.
