4. Setup
Setting up your YUNLEX NLS21 night light is simple and requires no tools.
- Unpack: Carefully remove the night light from its packaging.
- Choose Location: Select a standard wall outlet in your desired location (e.g., hallway, bedroom, bathroom). Ensure the outlet is easily accessible and not obstructed.
- Plug In: Insert the night light directly into the wall outlet. Ensure it is securely plugged in.


5. Operating Instructions
The YUNLEX NLS21 night light offers three sensor modes and two dimming methods for versatile use.
5.1. Sensor Modes
Use the slider switch on the side of the night light to select one of the three operating modes:
- Owl Mode: In this mode, the night light maintains a soft, gentle glow. When motion is detected, the brightness increases, then returns to the soft glow after 60 seconds of no motion. This is ideal for areas where you want continuous subtle light with temporary brighter illumination when needed, such as hallways or kitchens.
- Light Sensor Mode (Dusk-to-Dawn): The night light automatically turns on when the ambient light is low (at night) and turns off when the ambient light is sufficient (during the day). No motion detection is involved in this mode. Perfect for bedrooms or stairwells where consistent low light is desired throughout the night.
- Motion Sensor Mode: The night light remains off during the day. In darkness, it will automatically turn on when motion is detected and turn off after 60 seconds of no motion. This mode is energy-efficient and suitable for areas where light is only needed when someone is present.


5.2. Dimming Options
The night light offers two ways to adjust its brightness:
- 5-Step Dimming: Briefly touch the touch-sensitive area on the front of the night light to cycle through 5 preset brightness levels.
- Stepless Dimming: Touch and hold the touch-sensitive area to smoothly adjust the brightness from 1% to 100%. Release your finger when the desired brightness is reached.
The night light features a brightness memory function. If the power remains connected, it will recall the last brightness setting used, so you do not need to reset it each time.


5.3. Decorative Stickers
The included decorative stickers allow you to personalize your night light, adding a fun and unique touch to its appearance.

6. Maintenance
To ensure the longevity and optimal performance of your YUNLEX NLS21 night light, follow these maintenance guidelines:
- Cleaning: Disconnect the night light from the power outlet before cleaning. Wipe the surface with a soft, dry cloth. Do not use liquid cleaners, abrasive materials, or solvents, as these can damage the product.
- Storage: If not in use for an extended period, unplug the night light and store it in a cool, dry place away from direct sunlight.
- Safety: The night light is constructed with a superior ABS fire-retardant casing and includes overcurrent protection for safety. Do not attempt to open or modify the device.
7. Troubleshooting
If you encounter any issues with your night light, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power, incorrect sensor mode, or too much ambient light. | Check if the night light is securely plugged in. Ensure the power outlet is functional. Verify the sensor mode setting (e.g., if in Motion Sensor mode, ensure there is darkness and motion). If in Light Sensor mode, ensure the room is dark enough. |
| Light does not dim or brightness is inconsistent. | Incorrect dimming method, or a temporary electrical fluctuation. | Ensure you are using the correct touch method for 5-step or stepless dimming. Unplug the night light for 10 seconds and plug it back in to reset. |
| Motion sensor is not responding. | Incorrect sensor mode, sensor obstructed, or insufficient darkness. | Ensure the night light is set to Owl Mode or Motion Sensor Mode. Check that the sensor lens is clean and unobstructed. The motion sensor only activates in dark conditions. |
| Light stays on constantly. | Set to Light Sensor Mode in a continuously dark area, or constant motion. | If in Light Sensor Mode, this is normal behavior in a dark environment. If in Owl or Motion Sensor Mode, ensure there is no continuous motion in front of the sensor. |
