6. Installation
Follow these steps to install your Goobay 55501 lamp socket:
- Disconnect Power: Before starting, ensure the power supply to the existing lamp socket or fixture is completely turned off at the circuit breaker.
- Remove Existing Bulb: Carefully unscrew the existing light bulb from its E27 socket.
- Screw in Sensor Socket: Screw the Goobay 55501 lamp socket into the existing E27 fixture. Ensure it is securely tightened.
- Insert New Bulb: Screw your E27 light bulb into the Goobay 55501 lamp socket.
- Restore Power: Turn the power supply back on at the circuit breaker.
Optimal Placement: For best motion detection, it is recommended to install the sensor at a height of approximately 2 to 3 meters. The microwave sensor operates by detecting changes in its electromagnetic field and can function through thin walls, doors, and glass.

7. Operating Instructions
The Goobay 55501 features two adjustable dials to customize its operation:
7.1. Adjusting Time Delay (TIME Dial)
The 'TIME' dial controls how long the light remains on after motion is detected and before it automatically switches off. Rotate the dial to set the desired duration:
- Rotate towards '–' for a shorter delay (minimum 15 seconds).
- Rotate towards '+' for a longer delay (maximum 300 seconds, or 5 minutes).
7.2. Adjusting Sensor Sensitivity (SENSOR Dial)
The 'SENSOR' dial adjusts both the motion detection sensitivity and the ambient light threshold for activation:
- Motion Sensitivity: Rotate towards '–' to decrease motion detection range/sensitivity. Rotate towards '+' to increase motion detection range/sensitivity.
- Light Threshold: The sensor is designed to activate automatically at dusk (approximately 3 lux). The 'SENSOR' dial can also influence this threshold. For operation only in darker conditions, set the dial towards '–'. For activation in brighter conditions, set it towards '+'.
Experiment with the settings to find the optimal configuration for your specific environment.
8. Maintenance
The Goobay 55501 lamp socket requires minimal maintenance.
- Cleaning: To clean the device, ensure the power is disconnected. Wipe the exterior with a soft, dry, lint-free cloth. Do not use liquid cleaners, sprays, or abrasive materials.
- No User-Serviceable Parts: There are no user-serviceable parts inside the device. Do not attempt to open or repair it.
