Setup and Installation
The under cabinet lights are designed for easy installation with built-in magnets. Follow these steps for optimal placement.
Installation Steps:
- Direct Magnetic Attachment: If installing on an iron surface (e.g., a metal cabinet), simply place the light directly onto the surface. The built-in magnets will hold it in place.
- Adhesive Installation (for non-iron surfaces):
- Step 1: Clean the desired installation surface thoroughly to ensure it is dry and free of dust or grease.
- Step 2: Peel off the protective film from one side of the adhesive tape on an iron sheet.
- Step 3: Firmly press the iron sheet onto the cleaned surface.
- Step 4: Once the iron sheet is securely attached, the light can be magnetically affixed to the iron sheet.
- Removal for Charging: When charging is needed, simply detach the light from the magnetic surface (either the iron cabinet or the installed iron sheet).

Operating Instructions
Understand how to use the various functions of your under cabinet lights.
Charging the Lights:
- Connect the provided USB-C charging cable to the light's charging port and the other end to a USB power source (computer, power bank, or USB outlet).
- A red light indicator signifies that the light is currently charging.
- A green light indicator signifies that the light is fully charged.
- Full charge typically takes 3-4 hours.
- Battery life: 5-80 hours on Always-on Mode (depending on brightness), or 7-25 days on Motion Sensor Mode (depending on frequency of use).

- Power Button (On/Off/Mode Selection):
- Click Once: Turns the light ON (Always-on Mode).
- Click Twice: Activates Motion Sensor Mode.
- Click Three Times: Turns the light OFF.
- Light Mode Button (Color Temperature/Brightness):

Motion Sensor Functionality:
- In Motion Sensor Mode, the light will automatically turn on when human motion is detected within a 10ft (3m) range and a 100° detection angle.
- The light will automatically turn off after approximately 20 seconds of no detected movement in dark environments.
- The motion sensor is most effective in dim light or darkness.

Maintenance
To ensure the longevity and optimal performance of your under cabinet lights, follow these simple maintenance guidelines:
- Cleaning: Wipe the surface of the lights with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or electronic components.
- Charging: Recharge the lights regularly as needed. Avoid completely draining the battery frequently, as this can reduce overall battery lifespan.
- Storage: If storing the lights for an extended period, charge them to about 50% capacity and store them in a cool, dry place away from direct sunlight and extreme temperatures. Recharge every few months to prevent deep discharge.
- Water Exposure: These lights are designed for indoor use and are not water-resistant. Avoid exposing them to water or high humidity.
Troubleshooting
If you encounter any issues with your under cabinet lights, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | Battery is depleted. Incorrect mode selected. | Charge the light fully. Press the power button to cycle through modes (Always-on, Motion Sensor, Off). |
| Motion sensor not working. | Light is not in Motion Sensor Mode. Environment is too bright. Obstruction blocking sensor. | Ensure the light is in Motion Sensor Mode (press power button twice). The sensor works best in dim or dark conditions. Clear any objects blocking the sensor. |
| Light turns off too quickly or stays on too long. | Continuous motion detected (stays on). No motion detected for 20 seconds (turns off). | This is normal behavior for the motion sensor mode. Ensure the light is placed where motion is expected. |
| Battery life is shorter than expected. | Frequent activation in motion sensor mode. High brightness setting in Always-on mode. Battery degradation over time. | Reduce frequency of activation if possible. Lower brightness setting. Ensure full charge cycles. If issues persist, contact support. |
| Light is not sticking to surface. | Surface is not iron or not clean. Adhesive tape not applied correctly. | Ensure surface is clean and dry. Use the included iron sheets with adhesive tape for non-iron surfaces. Apply firm pressure when attaching adhesive. |
If the problem persists after trying these solutions, please contact customer support.
