- Position the spotlights in desired areas such as gardens, pathways, driveways, or pool areas.
Installation Methods:
The T-SUNUS Solar Landscape Spotlights offer two installation options:

- Attach the smaller ground stakes to the bottom of each spotlight.
- Firmly drive the stakes into the ground in your chosen locations.

- The spotlights can also be mounted on a wall using screws, or simply placed on the ground without stakes.

Operating Instructions
The T-SUNUS Solar Landscape Spotlights feature automatic operation and selectable lighting modes.
Automatic On/Off Function:
The lights are designed to automatically turn on at dusk and turn off at dawn, recharging during the day. Ensure the solar panel is clean and unobstructed for optimal performance.
