Operating Instructions
Your NIORSUN Solar Post Lights are designed for automatic operation:
- Automatic On/Off: Once installed and the switch is set to "ON", the lights will automatically turn on at dusk and turn off at dawn.
- Charging: The integrated solar panel charges the internal battery during the day. A full charge typically requires 4-6 hours of direct sunlight.
- Lighting Modes: The selected lighting mode (Flickering Flame, Warm White, Neutral White, or Cool White) will activate automatically when the lights turn on.

Maintenance
To ensure the longevity and optimal performance of your solar lights, consider the following maintenance tips:
- Clean Solar Panels: Regularly wipe the solar panel with a soft, damp cloth to remove dust, dirt, and debris. A clean panel ensures efficient charging.
- Clear Obstructions: Ensure no trees, bushes, or structures are blocking direct sunlight from reaching the solar panel, especially during peak charging hours.
- Battery Replacement: The internal rechargeable battery has a limited lifespan. If the light duration significantly decreases after prolonged use, the battery may need replacement. Refer to the specifications for battery type.
- Weather Resistance: While IP64 waterproof, extreme weather conditions (e.g., prolonged heavy snow cover) may temporarily affect performance. Clear snow from the solar panel as needed.
