5nm Battery Operated Marine Nav Lights Solar Powered Navigation Lights For Buoys
5NM | Solar Powered | IP68 Waterproof | IALA Compliant | OEM Available
The DX-ML550 is a fully integrated solar LED marine lantern engineered for buoys, beacons, and fixed coastal structures. It operates completely autonomously with four 7W monocrystalline solar panels and a high-capacity LiFePO₄ battery rated for over 15 years of service life. The lantern automatically turns on at dusk and off at dawn, and can run for up to 200 hours continuously on a full charge.
Equipped with a professional-grade acrylic optical lens, the DX-ML550 delivers high-efficiency light output in Red, Green, Yellow, White, or Blue, all in full compliance with IALA standards. With 256 selectable flash patterns and options for floating or fixed installations, it provides unmatched versatility and durability in harsh marine environments.
Constructed with UV-resistant, impact-resistant housing, and certified to IP68, the DX-ML550 is capable of operating even while fully submerged, making it ideal for saltwater exposure, high humidity, and long-term field deployment.
