High capacity solar powered marine signal light with a 2200mAh battery for long lasting nighttime visibility. Eight high intensity LEDs provide clear visibility from 0 to 2.0 km, delivering a reliable navigational aid for safe operations. Efficient operation with nominal 3.7V, charging current 60 mA and discharge current 180 mA to optimize battery life in marine conditions. IP65 rated weather proof design protects against dust and low pressure water jets from any direction, and operates in fog and temperatures from -10 C to 50 C. No external power is required at night, making it suitable for deployment on buoys, docks, or vessels with minimal setup and maintenance. Use scenarios: - Mark channels and harbor approaches at night to improve safety and situational awareness. - Provide a visible beacon in foggy conditions to reduce collision risk. - Serve as a temporary beacon for mooring, dredging, or construction projects along coastal areas.
