4. Setup and Installation
The NIORSUN Solar Stair Lights offer two convenient installation methods to suit your needs:
- Method 1: With 3M Adhesive Tape
This method provides a quick and easy installation. Simply peel off the protective film from the pre-applied 3M adhesive tape on the back of the light and firmly press the light onto a clean, dry, and smooth surface. Ensure the surface is free of dust and debris for optimal adhesion.
- Method 2: With Screws
For a more secure and stable installation, especially on rougher surfaces or in high-traffic areas, use the provided screws. Mark the desired drilling points, drill pilot holes if necessary, and then secure the light using the screws. This method ensures long-term stability.
Important: Choose a location where the solar panel can receive direct sunlight for 4-5 hours daily to ensure optimal charging and lighting performance.

This diagram illustrates the two primary ways to install the solar stair lights. Method 1 involves using the pre-applied 3M adhesive tape for a convenient and fast setup. Method 2 provides a more secure and stable installation using screws, suitable for various surfaces.
5. Operating Instructions
The NIORSUN Solar Stair Lights are designed for automatic operation:
- Automatic On/Off: The lights feature a built-in light sensor that automatically turns them on at dusk and off at dawn. No manual operation is required after initial setup.
- Charging: During the day, the integrated solar panel converts sunlight into electricity, charging the internal AA battery. A full charge typically requires 4-5 hours of direct sunlight.
- Lighting Duration: Once fully charged, the lights can provide 8-10 hours of continuous illumination throughout the night.

This image demonstrates the automatic operation of the solar lights. During the day, the lights charge for 4-5 hours under direct sunlight. At night, they automatically turn on and provide illumination for 8-10 hours, ensuring consistent lighting from dusk till dawn.
6. Maintenance
To ensure the optimal performance and longevity of your solar lights, follow these simple maintenance guidelines:
- Clean Solar Panel: Regularly wipe the solar panel with a soft, damp cloth to remove dirt, dust, leaves, or snow. A clean panel ensures efficient sunlight absorption and charging.
- Clear Obstructions: Ensure no trees, buildings, or other objects are blocking direct sunlight from reaching the solar panel throughout the day.
- Battery Replacement: The included AA battery is rechargeable. If the light's performance significantly diminishes over time, the battery may need replacement. Use a high-quality rechargeable AA battery.
- Weather Resistance: The lights are IP67 waterproof, designed to withstand rain, snow, and other harsh weather conditions. However, avoid submerging them in water.

This image highlights the IP67 waterproof rating of the solar light, showing it performing reliably in wet conditions. The rating ensures the light is protected against dust and water jets, making it suitable for various outdoor weather conditions including rain, heat, and frost.
7. Troubleshooting
If your solar lights are not functioning as expected, please refer to the following common issues and solutions:
- Light does not turn on at night:
- Ensure the solar panel is clean and free from obstructions.
- Verify the light is placed in a location that receives at least 4-5 hours of direct sunlight daily.
- Check if the battery is properly inserted and making good contact.
- The battery might be depleted. Allow it to charge for 1-2 sunny days. If the issue persists, consider replacing the rechargeable AA battery.
- Light is dim or only stays on for a short period:
- The solar panel may not be receiving enough direct sunlight for a full charge. Relocate the light to a sunnier spot.
