5. Installation
The T-SUNUS Solar Spot Lights offer two primary installation methods: ground staking and wall mounting.
5.1. Ground Staking Installation
- Attach the ground stake to the bottom of the light head and the solar panel.
- Select a location in your garden, pathway, or yard where the light is desired and the solar panel can receive maximum direct sunlight.
- Firmly push the stakes into the ground until stable.
- Connect the light head to the solar panel using the 9.8ft cable. Ensure the connection is secure.
- Adjust the angle of the solar panel (up to 90°) to face the sun and the light head (up to 180°) to illuminate the desired area.
5.2. Wall Mounting Installation
- Choose a suitable wall location for the light head and the solar panel.
- Use the provided screws to securely attach the light head bracket and solar panel bracket to the wall.
- Connect the light head to the solar panel using the 9.8ft cable. Ensure the connection is secure.
- Adjust the angle of the solar panel and light head as needed.

6. Operating Instructions
6.1. Initial Setup
Before first use, ensure the solar panel is exposed to direct sunlight for at least 8-12 hours to fully charge the internal battery. The lights will automatically turn on at dusk once sufficiently charged.
6.2. Power On/Off and Mode Selection
Each light head has a power button. Press the button to cycle through the modes:
- First Press: High Brightness Mode
- Second Press: Low Brightness Mode
- Third Press: Turn Off
To test the light during the daytime, cover the solar panel completely. The light should illuminate if it has sufficient charge and is in an ON mode.

7. Maintenance
- Clean Solar Panel: Regularly wipe the solar panel with a soft, damp cloth to remove dust, dirt, or debris. A clean panel ensures maximum sunlight absorption and charging efficiency.
- Check Connections: Periodically inspect the cable connections between the solar panel and the light head to ensure they are secure and free from damage.
- Clear Obstructions: Ensure no trees, bushes, or other objects are blocking direct sunlight from reaching the solar panel, especially during winter months.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on at night. | Insufficient solar charge. Light is in OFF mode. Solar panel is covered or in shade. | Ensure solar panel receives 6-8 hours of direct sunlight. Press the power button to cycle to High or Low mode. Relocate solar panel to a sunnier spot. |
| Light duration is short. | Insufficient solar charge. Battery capacity reduced due to age or extreme temperatures. | Ensure solar panel receives maximum direct sunlight. Clean the solar panel. Consider replacing the battery if performance significantly degrades over time (contact support for guidance). |
| Light is dim. | Insufficient solar charge. Solar panel is dirty. Light is in Low Brightness mode. | Ensure adequate charging. Clean solar panel. Press the power button to switch to High Brightness mode. |
| Light flickers. | Loose connection. Low battery charge. | Check and secure all cable connections. Allow the unit to charge fully in direct sunlight. |
