Setup and Installation

1. Initial Charge

2. Choose Installation Method
Your T-SUNUS Solar Spot Lights offer two primary installation methods:
- Ground Installation: Attach the ground stake to the bottom of each spotlight and the solar panel. Insert the stakes firmly into soft ground in your desired location. Ensure the solar panel is positioned where it receives maximum direct sunlight throughout the day.
- Wall Mounting: Use the provided screws and wall anchors to mount the spotlights and the solar panel onto a wall or fence. Mark the desired drilling spots, drill pilot holes, insert anchors (if needed), and secure the fixtures with screws. Ensure the solar panel is mounted in a location with ample direct sunlight.

Operating Instructions
The T-SUNUS Solar Spot Lights are designed for simple, automatic operation.
1. Automatic Dusk-to-Dawn Operation
The lights are equipped with a light sensor that automatically detects ambient light levels. They will turn on automatically at dusk and turn off at dawn, conserving energy during daylight hours.
2. Brightness Modes
The solar panel features a button to cycle through two brightness modes:
- High Brightness Mode: Provides maximum illumination, typically lasting up to 6 hours on a full charge.
- Low Brightness Mode: Offers a softer light, extending operation time up to 12 hours on a full charge.
Press the button on the back of the solar panel once for High Brightness, twice for Low Brightness, and three times to turn the lights off. Select your preferred mode based on your lighting needs and desired operating duration.
