Required materials and tools before connecting the lighting
Before you start connecting new lighting, you need the right materials and tools. You can find a handy overview here:
- Wiring & Cables – for example brown/black, blue, and yellow/green for the correct connection.
- Terminal blocks or wire connectors – to safely connect cables to the fixture.
- Switch or LED dimmer – necessary if you want to switch or dim the lighting.
- Junction box – required if there is no connection point available yet on the ceiling or wall.
- Conduit pipes – used to route cables neatly and safely through the wall or ceiling.
- Voltage tester – essential for safely checking whether there is current in the wires.
- Wire stripper – indispensable for correctly stripping cables and wires.

Wiring & Power
Is switchable wiring already available at the location where you plan to install the lighting? If not, you will need the materials listed above.
In many houses, there is wiring next to the front door. There, you can install a wall light, for example. In many cases, however, this wiring is permanently live. If you want to switch or dim the lighting, you therefore need to adjust the wiring and install a switch.
Running new wiring sounds simple, but it is often more complicated than you think. If there are no cables available to connect the lighting, you must run new lines between the fuse box and the fixture. If you get stuck, we recommend consulting an electrician.
Chasing slots in the wall
If no wiring is present yet, you should ask yourself: "Can this wiring be routed to the right place relatively easily?" If that is not possible, it must be run through the wall.That is of course no problem. However, please note that in this case, channels will need to be chased into the wall to conceal the cables. Afterwards, the wall will need to be replastered, which entails additional labor and costs.
Useful tips for connecting lighting
When connecting or purchasing lighting, there are a few points to keep in mind depending on the type of lamp:
- Recessed spotlights – Always check the correct drilling diameter and ensure there is sufficient recess depth.
- Pendant lights and surface-mounted spotlights – Pay attention to the size of the junction box and whether the ceiling plate covers it properly.
- Wall lights – Check the connection in the wall and whether the lamp fits neatly over it.
- Dimming the lighting – If you want to dim, replace the switch with an LED dimmer and pay attention to the maximum wattage.
- Track lighting – Track systems are often narrow and usually do not fit over a junction box. Use a separate cover plate for this.
- LED strips – These cannot be connected directly to the wiring. You will need a transformer, which is best hidden neatly out of sight.
- Individual light sources – Always check the fitting of your lamp. If you want to dim, choose a dimmable light source.
- Cabinet lighting – If you are replacing old 12-volt lighting under kitchen cabinets with LEDs, the transformer must also be replaced.
Connecting lighting; step-by-step guide
Would you like to connect the lighting yourself? Then follow this step-by-step guide for a safe and neat installation:
Step 1: Safety first
Turn off the main switch or circuit breaker so that there is no longer any voltage on the circuit. Always check this with a voltage tester before you begin.
Step 2: Organize the wires
Take the wires out of the junction box and connect them to a terminal block if necessary to keep things organized.
Step 3: Mounting the lamp bracket
Securely attach the included bracket to the ceiling with screws. This forms the base for hanging the lamp.
Step 4: Strip wires
Remove a small piece of the insulation from the lamp wires so that enough copper is exposed to ensure good contact.
Step 5: Connect wires
Connect the lamp wires to the terminal block. Ensure that the copper wires make full contact with the connection point and tighten the screws securely.
Blue (N) = Neutral wire
Black (L) = Live wire
Yellow/Green (⏚) = Earth
Always double-check the label or marking at the connection point for safety.
Step 6: Attach the lamp
Mount the lamp to the bracket using the supplied screws.
Step 7: Insert the light source
Screw the light source into the fitting or click it into place, depending on the type of lamp.
Step 8: Turn on the power
Turn the main switch or circuit breaker back on to restore the power supply.
Step 9: Test the lamp
Turn on the lighting using a switch or LED dimmer and check if everything is working properly.
