1. Introduction
This manual provides instructions for the KOOPER Solar Lanterns Outdoor Waterproof (Model TLL090). These lanterns are designed for outdoor decorative lighting, featuring solar charging, automatic operation, and a durable, waterproof construction. Please read this manual thoroughly before installation and use to ensure optimal performance and longevity of your solar lanterns.
The package includes 4 solar lanterns and this user manual.
2. Setup
- Unpack: Carefully remove all lanterns and components from the packaging.
- Activate: Locate the ON/OFF switch, typically found on the underside of the solar panel. Slide the switch to the "ON" position.
- Remove Protective Film: Gently peel off any clear protective plastic film from the surface of the solar panel. This is crucial for efficient solar charging.
- Placement: Choose an outdoor location that receives 6-8 hours of direct, unobstructed sunlight daily. Ensure no shadows from trees, buildings, or other structures fall on the solar panel during the day.
- Installation: Use the integrated hook to hang the lanterns from a tree branch, shepherd's hook, or wall bracket. Alternatively, place them on a flat surface such as a table or step.

3. Operation
- Automatic Charging: Once the switch is in the "ON" position and the protective film is removed, the lanterns will automatically absorb sunlight and charge their internal battery during the day.
- Automatic Illumination: A built-in light sensor detects ambient light levels. At dusk, when light levels are low, the lanterns will automatically turn on.
- Lighting Duration: On a full charge (typically 6-8 hours of direct sunlight), the lanterns will provide 10-14 hours of continuous illumination.
- Automatic Shut-off: At dawn, as light levels increase, the lanterns will automatically turn off and resume charging.

4. Maintenance
- Cleaning the Solar Panel: To ensure optimal charging efficiency, periodically wipe the solar panel surface with a soft, damp cloth to remove any accumulated dust, dirt, leaves, or snow. Avoid abrasive cleaners.
- Clear Obstructions: Regularly check that no new foliage or objects are obstructing the solar panel's exposure to direct sunlight.
- Weather Resistance: The lanterns are designed with an IP65 waterproof rating, making them resistant to rain, snow, wind, and heat. They do not require special protection during most weather conditions.

5. Troubleshooting
- Lanterns do not light up at night:
- Ensure the ON/OFF switch is in the "ON" position.
- Verify the solar panel is clean and free from any obstructions.
- Confirm the lantern receives 6-8 hours of direct sunlight daily. Relocate if necessary.
- Allow the lantern to charge for at least 2 full sunny days before expecting full performance, especially after initial setup or prolonged storage.
- Lanterns light up for a short duration:
- The solar panel may not be receiving enough direct sunlight for a full charge. Check placement and obstructions.
- The battery may not be fully charged due to cloudy weather or insufficient sun exposure. Allow more charging time.
- Extreme cold weather can reduce battery efficiency and overall lighting duration.
