4. Setup and Installation
The Steinel L 840 SC is designed for wall mounting. Ensure the chosen location provides optimal coverage for the motion sensor and is within reach of the electrical supply.
4.1 Mounting Location Considerations
- Height: For optimal motion detection, mount the light at a height of approximately 1.8 to 2.5 meters.
- Sensor Range: The 160° high-frequency sensor has a range of up to 5 meters. Consider the desired detection area when positioning.
- Obstructions: Avoid mounting near large metal objects, dense foliage, or other sources of interference that might affect sensor performance.
4.2 Installation Steps
- Disconnect Power: Turn off the main power supply to the installation area at the circuit breaker. Verify that the power is off using a voltage tester.
- Prepare Mounting Surface: Mark the drilling points on the wall using the light fixture as a template. Drill holes and insert the provided wall plugs.
- Wiring: Connect the electrical wires (Live, Neutral) from your household wiring to the corresponding terminals on the light fixture. Ensure secure connections.
- Mount the Fixture: Secure the light fixture to the wall using the provided screws and spacers. Ensure it is firmly attached.
- Restore Power: Once installation is complete and all connections are secure, restore power at the circuit breaker. The light will perform an initial self-test.

5. Operating Instructions
The Steinel L 840 SC is primarily controlled and configured via the Steinel Connect app.
5.1 Steinel Connect App
The free Steinel Connect app allows you to customize various settings of your L 840 SC light.
- Download the App: Download the "Steinel Connect" app from the Google Play Store (for Android devices) or the Apple App Store (for iOS devices).
- Pairing: Follow the in-app instructions to pair your L 840 SC light via Bluetooth. Ensure Bluetooth is enabled on your smartphone.
- Configuration: Once paired, you can access and adjust the following settings:
- Motion Sensor Settings: Adjust the detection range (up to 5m) and sensitivity in 3 directions to fine-tune motion detection. The sensor is designed to ignore small animals and swaying branches.
- Light Duration: Set how long the main light stays on after motion is detected.
- Twilight Setting: Define the ambient light level at which the sensor becomes active.
- Night Light (Basic Light): Enable a continuous low-level illumination (10% to 50% brightness) during darkness for constant ambient lighting.
- Continuous Light: Activate a 4-hour continuous full brightness mode for extended illumination when needed.
- Dimmable Main Light: Adjust the brightness of the main light output from 50% to 100%.
- Light Groups (Bluetooth Mesh): Connect multiple Steinel Connect lights to create groups and control them simultaneously for synchronized lighting scenarios.

5.2 Motion Sensor Operation
The L 840 SC features an invisible 160° high-frequency sensor that reliably detects human movement.
- Detection Principle: The sensor emits high-frequency electromagnetic waves and detects changes in the echo caused by movement within its detection zone.
- Intelligent Detection: It is optimized to differentiate between human movement and smaller disturbances like pets or wind-blown foliage, reducing false triggers.
- Adjustable Range: The detection range can be precisely adjusted via the app to suit the specific requirements of your installation area.

6. Maintenance
The Steinel L 840 SC is designed for low maintenance. The integrated LED system has a long lifespan of approximately 50,000 hours, meaning bulb replacement is not required.
- Cleaning: To clean the fixture, wipe it with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the surface.
- Inspection: Periodically check the fixture for any signs of damage or loose connections. If any issues are found, disconnect power and consult a qualified electrician.
7. Troubleshooting
If you encounter issues with your Steinel L 840 SC, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power supply; incorrect wiring; twilight setting too high. | Check circuit breaker; verify wiring connections; adjust twilight setting in the app. |
| Light stays on continuously. | Continuous light mode activated; constant motion in detection area; faulty sensor. | Deactivate continuous light in the app; check for persistent movement; contact support if sensor is faulty. |
| Sensor does not detect motion. | Detection range too small; sensor obstructed; incorrect sensitivity setting. | Increase detection range in the app; clear obstructions; adjust sensor sensitivity. |
| Cannot connect to the app. | Bluetooth off; light not in pairing mode; app issues. | Ensure Bluetooth is on; restart the light; restart the app or reinstall it. |
