Why you need to be careful when connecting lamps

The good news: With a little know-how, the right preparation and these instructions, you can do it yourself - even as a beginner.
Which cables belong where? (colors explained)
When connecting a lamp, you almost always come across three cables. The colors will help you connect them correctly:
- Black or Brown = Phase (L) → carries the current.
- Blue = neutral conductor (N) → closes the circuit.
- Yellow-green = protective conductor (PE) → ensures safety.
Note: Brown/black for the lamp, blue too, and yellow-green is the protection.
💡 Additional tip:
Color standards are sometimes missing in old houses. So be sure to use one Voltage testerbefore connecting cables. This way you avoid dangerous mix-ups.
Step-by-step instructions: Connect the lamp securely
Follow these steps if you want to connect your lamp:
1. Switch off the power!
Before you get started, turn off the fuse in the fuse box. Use a voltage tester to check whether there is really no more current on the line.
2. Remove old lamp
Unscrew the old lamp and carefully release the cables from the clamp. Be careful not to damage the cables.
3. Prepare cables
Check the cable ends. If necessary, re-insulate 0.5-1 cm. Bend the ends straight so that they fit tightly into the luster terminal.
4. Connect cable correctly
Connect the lamp cables to the ceiling cables:
- Brown/Black (Lamp) → Brown/Black (Ceiling)
- Blue (lamp) → Blue (ceiling)
- Yellow-green (lamp) → yellow-green (ceiling)
💡 Additional tip:
Use modern Plug-in terminals instead of classic luster terminals. They are safer and prevent loose contacts that can cause flickering later.
5. Attach the lamp
Screw or clamp the lamp to the designated bracket on the ceiling or wall. Make sure you have a secure hold - especially with heavy models.
6. Testing
Turn the power back on and check if the lamp works. If not: turn the fuse off again, check the cable connections.

➡️ Cause: Incorrect bulb or too high wattage.
➡️ Solution: Only use the recommended wattage - preferably LED, as they hardly generate any heat.
Common mistakes when connecting a lamp
- ❌ Power not switched off – highest risk!
- ❌ Phase and neutral conductors swapped.
- ❌ Cable ends stripped too short – can slip out.
- ❌ Lamp attached to dowels that are too weak – risk of falling.
💡 Additional tip:
Mark cables with small ones Cable clips or labelsif there are several cables in the ceiling. This saves time and prevents mix-ups.
