- Activate the Light: Before first use, ensure the internal battery is properly connected. Some units may have a pull tab or require a slight twist to activate the switch.
- Assemble the Light: Attach the mushroom-shaped light unit to the top of the ground stake. Ensure it is securely fastened.

- Choose Location: Select an outdoor location that receives direct sunlight for 6-8 hours daily. This is crucial for optimal charging and performance. Avoid placing lights under trees, eaves, or other shaded areas that might block sunlight or artificial light sources at night, which can interfere with the automatic sensor.
- Insert into Ground: Gently push the assembled light, with the ground stake first, into the soil. If the ground is too hard, it is recommended to loosen the soil or dig a small hole first to avoid damaging the stake.

Once installed, the lights will automatically charge during the day and illuminate at night.
4. Operating Instructions
The Greluna Solar Pathway Lights are designed for fully automatic operation:
- Automatic Charging: During daylight hours, the integrated solar panel on top of each light unit will absorb sunlight and convert it into electrical energy, which is stored in the rechargeable AAA battery.

The top part shows the lights in a garden during the day with a sun icon and text "Auto Charging 6-8 Hours in strong light." The bottom part shows the lights illuminating a pathway at night with a crescent moon icon and text "Auto Working 8-10 Hours in dark light."
- Automatic Illumination: At dusk, a built-in light sensor will detect the decrease in ambient light and automatically turn on the LED light. The lights will provide warm, ambient illumination for 8-10 hours on a full charge.
- Automatic Shut-off: At dawn, the light sensor will detect the return of daylight and automatically turn off the LED light, resuming the charging cycle.
5. Maintenance
To ensure optimal performance and longevity of your Greluna Solar Pathway Lights, follow these maintenance guidelines:
- Clean Solar Panel: Periodically wipe the solar panel with a soft, damp cloth to remove dirt, dust, or debris. A clean solar panel ensures maximum sunlight absorption and efficient charging.
- Battery Replacement: The included AAA rechargeable battery has a limited lifespan. If the lights begin to dim or do not stay lit for the expected duration, the battery may need replacement. Use a standard 1.2V AAA rechargeable battery.
- Winter Care: While designed for all-weather durability, prolonged exposure to heavy snow or ice can affect performance. Consider clearing snow from the solar panels or storing the lights indoors during extreme winter conditions for best results.
