Setup and Installation
The T-SUNUS Solar Landscape Spotlights offer two primary installation methods:
1. Ground Stake Installation
- Assemble the Stakes: Attach the ground stake to the bottom of both the solar panel unit and the spotlight unit.
- Position the Solar Panel: Choose a location for the solar panel that receives maximum direct sunlight throughout the day (6-8 hours recommended). Insert the stake firmly into the ground. Adjust the solar panel angle (up to 90 degrees) to face the sun for optimal charging.
- Position the Spotlight: Choose your desired location for the spotlight. Insert its stake firmly into the ground. Adjust the spotlight angle (up to 180 degrees) to illuminate the target area.
- Connect the Cable: Connect the extension cable from the solar panel to the spotlight. Ensure the connection is secure.
2. Wall Mount Installation
- Mark Drilling Points: Hold the mounting bracket of the solar panel or spotlight against the desired wall surface. Mark the positions for the screws.
- Drill Holes: Drill holes at the marked positions. Insert wall anchors if necessary for your wall type.
- Secure the Unit: Align the mounting bracket with the drilled holes and secure it with screws.
- Adjust and Connect: Adjust the solar panel and spotlight to their desired angles. Connect the extension cable between the solar panel and the spotlight.

Operating Instructions
- Initial Charge: Before first use, ensure the solar panel is exposed to direct sunlight for at least 8 hours to fully charge the battery.
- Power On/Off: Locate the push button on the back of the spotlight. Press and hold the button for 3-5 seconds to turn the light ON or OFF.
- Select Lighting Mode: Once the light is ON, short press the button to cycle through the available lighting modes:
- High Light Mode: Provides brighter illumination for approximately 8 hours on a full charge.
- Low Light Mode: Provides softer illumination for approximately 12 hours on a full charge.
- Automatic Operation: The spotlights are equipped with a light sensor. They will automatically turn on at dusk and turn off at dawn, provided the switch is in the ON position and the battery has sufficient charge.
Maintenance
- Clean Solar Panel: Regularly wipe the solar panel with a soft, damp cloth to remove dust, dirt, leaves, or snow. A clean panel ensures maximum charging efficiency.
- Inspect Cables: Periodically check the connection cables for any signs of wear, damage, or loose connections.
- Battery Longevity: The integrated battery is designed for long-term use. If the light output significantly decreases over time, it may indicate the battery is reaching the end of its lifespan. Battery replacement is not user-serviceable.
- Environmental Conditions: While IP65 waterproof, extreme weather conditions (e.g., prolonged heavy rain, blizzards) may temporarily affect performance. Ensure the units are not submerged.
