Setup and Installation
- Power Off: Before installation, ensure the power supply to the light fixture is turned off at the main switch.
- Screw In: Carefully screw the Elrigs LED E27 bulb into a standard E27 socket.
- Power On: Restore power to the light fixture.
- Maintain Switch ON: After installation, ensure the wall switch (if any) connected to the fixture remains in the "ON" position for the bulb's sensor functions to operate correctly.
- Placement Considerations:
- The bulb is suitable for both indoor and outdoor covered fixtures.
- For optimal performance and to avoid interference, maintain a minimum distance of 2 meters (6.56 feet) between two Elrigs motion sensor bulbs if installed in parallel.
- While the radar sensor can detect through some materials like glass or thin walls, enclosed glass covers may reduce detection sensitivity. Adjust the detection range accordingly if using such fixtures.

Operating Instructions and Adjustments
The Elrigs motion sensor bulb features three adjustable settings to customize its operation:
- Detection Range: Adjusts the distance at which motion is detected.
- Range: 1 to 8 meters.
- Use the provided mini screwdriver to turn the dial.
- The radar motion sensor can detect movement through glass, wood, and thin walls.
- Illumination Duration: Sets how long the bulb remains lit after motion is detected.
- Duration: 3 seconds to 5 minutes.
- If continuous motion is detected, the illumination period will extend from the last detected movement plus the set duration.
- Light Sensitivity (Lux): Determines the ambient light level below which the bulb will activate upon motion detection.
- Sensitivity: 1 to 3000 Lux.
- The bulb will only turn on if the ambient light is below the chosen Lux value AND motion is detected.
- If ambient light is above the set Lux value, the bulb will remain off, even if motion is detected.

Image: This diagram explains how the light sensor works. The bulb remains off if ambient light is brighter than the set threshold. It activates only when ambient light is below the threshold AND motion is detected.
Maintenance
- Cleaning: Ensure the power is off before cleaning. Wipe the bulb with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Inspection: Periodically check the bulb and fixture for any signs of damage or loose connections.
- Environment: Avoid installing the bulb in areas with extreme temperatures or high humidity, which can affect its lifespan and performance.
