2. Setup
2.1 Battery Installation
- Locate the battery compartment on the back of the NIGHTLUX unit.
- Open the battery compartment cover.
- Insert three (3) 1.5V LR03 (AAA) alkaline batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
Note: Batteries are included with the product. Ensure the battery compartment is closed securely to maintain IP54 protection.
2.2 Mounting
The NIGHTLUX Hall Night Light offers flexible mounting options. Accessories for mounting are included.
- Adhesive Strips: For quick and easy attachment to smooth, clean surfaces. Ensure the surface is dry and free of dust before applying.
- Screws: For a more permanent installation. Mark the desired mounting location, drill pilot holes if necessary, and secure the unit using the provided screws.
The light steering can be individually adjusted after mounting.
3. Operating Instructions
3.1 Mode Selection
The NIGHTLUX unit features a switch to select between operating modes:
- AUTO Mode: In this mode, the built-in light and motion sensors control the illumination. The light will activate only when motion is detected in low-light conditions, ensuring energy-efficient operation.
- ON/OFF Mode: This mode allows you to manually turn the light ON or OFF. Select 'ON' for continuous illumination or 'OFF' to disable the light.
3.2 Sensor Functionality
The integrated motion and light sensors work together to provide optimal lighting:
- The motion sensor detects movement within its range.
- The light sensor assesses ambient light levels.
- In AUTO mode, the light will only activate if motion is detected and the ambient light is insufficient. This conserves battery life and ensures the light is only used when needed.
The NIGHTLUX provides a 4000K cool white light, offering clear vision and pleasant illumination suitable for hallways, entryways, or as outdoor pathway lights in sheltered areas.
4. Maintenance
4.1 Battery Replacement
When the light output diminishes or the unit stops responding, it is time to replace the batteries. Follow the battery installation steps in Section 2.1.
- Always replace all three AAA batteries at the same time.
- Use only new, high-quality alkaline batteries for optimal performance.
- Dispose of used batteries according to local regulations.
4.2 Cleaning
To clean the NIGHTLUX unit:
- Ensure the unit is switched OFF.
- Wipe the exterior with a soft, dry, or slightly damp cloth.
- Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the surface or internal components.
- Avoid getting moisture into the battery compartment or sensor areas.
5. Troubleshooting
If your OSRAM NIGHTLUX Hall Night Light is not functioning as expected, please refer to the following common issues and solutions:
- Light does not turn on:
- Check if the batteries are correctly installed and not depleted. Replace if necessary.
- Ensure the unit is in 'AUTO' mode if expecting sensor activation, or 'ON' mode for continuous light.
- In 'AUTO' mode, verify that ambient light conditions are dark enough for the light sensor to trigger.
- Confirm there is actual motion within the sensor's detection range.
- Light stays on continuously (in AUTO mode):
- Check for constant motion within the sensor's range.
- Ensure the light sensor is not obstructed, causing it to detect continuous darkness.
- Light is dim or flickers:
- This typically indicates low battery power. Replace all batteries with new ones.
- Motion sensor is not detecting movement:
- Ensure the sensor lens is clean and unobstructed.
- Verify the unit is mounted at an appropriate height and angle for the desired detection area.
If these steps do not resolve the issue, please refer to the support information.
