Troubleshooting Lighting

Always unplug the luminaire/spotlight when you initiate troubleshooting. 


In the event of a damaged or broken light fixture

The LED module
The light source in the light fixture should only be replaced by the manufacturer, the manufacturer’s service agent, or a similarly qualified person.

Connection cable
If the connection cable or cord of this fixture is damaged, the light fixture must NOT be connected. The cable must be replaced by the manufacturer, the manufacturer’s service agent or a certified electrician for the product to be safe.


The luminaire/spotlight does not light up

  • Does the luminaire/spotlight have any physical damage on the cord or product?
  • Is the luminaire/spotlight installed and connected in accordance with the installation instructions?
  • Control that the luminaire/spotlight is plugged in.
  • Control that the luminaire/spotlight is on the correct phase L1 L2 L3.
  • Test whether the luminaire/spotlight works in a different socket/block/lighting track.
  • Control that there is power on the quick connection system/lighting track.
  • Are the fuses/residual current circuit breaker on?


Do you have a quick connection system or light control installed?

  • Control that the correct phase is selected on the cabling/quick connection system, check the couplings.
  • Control that the plug is inserted correctly into the coupler blocks.
  • If you have power for all luminaires, but nothing is lit, check with the building caretaker if there is any light control installed.
  • Always check before luminaire installation, that the luminaires are intended for the installed lighting control system.


Fuse or residual current circuit breaker triggers when the lights are on?

  • Check the number of luminaires per fuse, see product sheet for maximum number.
  • If the residual current circuit breaker triggers, there may be a grounding failure or short circuit in any luminaire.
