Setup & Installation
Before initial use, ensure the solar panel receives 6-8 hours of direct sunlight for a full charge. Avoid placing the solar panel near other light sources at night, as this may prevent the lights from activating automatically.
1. Ground Installation
- Attach the ground stake to the bottom of the solar panel and each spotlight.
- Select a location for the solar panel where it will receive maximum direct sunlight throughout the day.
- Insert the solar panel stake firmly into the ground.
- Position the spotlights in your desired area and insert their stakes firmly into the ground.
- Connect the cables from the spotlights to the solar panel. Ensure the connections are tight to maintain waterproof integrity.
- Adjust the angle of the solar panel (up to 90°) to optimize sun exposure and the light heads (up to 270°) to direct illumination.


2. Wall Installation
- Detach the ground stake from the solar panel and spotlights if they are already attached.
- Choose a wall location for the solar panel that receives ample direct sunlight. Mark the drilling points.
- Drill holes, insert anchors, and secure the solar panel to the wall using the provided screws.
- Repeat the process for mounting the spotlights in your desired locations on a wall or fence.
- Connect the cables from the spotlights to the solar panel, ensuring secure and waterproof connections.
- Adjust the angle of the solar panel and light heads as needed.
Operation
The T-SUNUS RGB Solar Landscape Spotlights are designed for simple operation with automatic functions and customizable color settings.
1. Initial Activation
- Locate the power button on the back of the solar panel.
- Press and hold the button for approximately 3 seconds to turn the lights ON. The lights will enter the 6-color cycling mode automatically.
- To test during the day, cover the solar panel completely with your hand for a few seconds. The lights should turn on, allowing you to preview the colors.

2. Color Modes
- 6-Color Cycling Mode: After initial activation (long press), the lights will automatically cycle through Red, Green, Blue, Indigo, Purple, and the unique warm color.
- Fixed Color Mode: While in 6-color cycling mode, short press the power button to pause on the current color. Each subsequent short press will cycle to the next fixed color.

3. Automatic Dusk-to-Dawn Function
- Once activated, the lights will automatically turn on when it gets dark and turn off when daylight is detected.
- Ensure the solar panel is positioned to receive adequate sunlight and is not obstructed or exposed to other light sources at night, which could interfere with the automatic sensor.

Maintenance
- Cleaning: Regularly wipe the solar panel with a soft, damp cloth to remove dust, dirt, or debris. A clean panel ensures optimal charging efficiency.
- Positioning: Periodically check that the solar panel is still in a position to receive maximum direct sunlight and is not shaded by new growth or obstructions.
- Connections: Ensure all cable connections remain tight and secure to maintain their waterproof seal.
- Battery: The internal battery is designed for long-term use. If performance significantly degrades over time, contact customer support for guidance. Do not attempt to replace the battery yourself unless specifically instructed by the manufacturer.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on at night. | Solar panel not receiving enough sunlight. | Relocate the solar panel to an area with 6-8 hours of direct sunlight. Ensure it's not shaded. |
| Solar panel is near another light source (e.g., porch light). | Move the solar panel away from other light sources that might interfere with the dusk sensor. | |
| Initial activation button not pressed. | Press and hold the power button on the solar panel for 3 seconds to activate. | |
| Lights are dim or only stay on for a short period. | Insufficient charging due to cloudy weather or dirty solar panel. | Clean the solar panel. Allow several days of full sunlight for the battery to fully charge. |
| Lights are not changing colors or stuck on one color. | Fixed color mode is active. | Short press the power button to cycle through fixed colors or return to cycling mode. |
