SOLAR-X-10NM is a high-intensity self-contained solar LED marine lantern built for long-range aids to navigation where visibility really matters. Its large solar array and high-capacity lithium battery sustain reliable dusk-to-dawn operation even through extended bad weather, while the daylight sensor and magnetic switch simplify deployment and storage. Users can select power, range and flash character via a Bluetooth 5.0 app, and GPS/BDS synchronisation plus optional NB-IoT, 4G or AIS connectivity enable coordinated, monitored lighting networks. Ideal for offshore buoys, fairway and channel markers, harbour approaches and other demanding marine navigation applications.
