20 NM solar-powered marine navigation lantern beacon light for buoys with AIS AtoN support
20NM｜Solar-Powered Marine Navigation Lantern
For Buoys｜With AIS AtoN Support
Discover high-performance, low-power navigation with our advanced marine AIS lantern, engineered for offshore environments, buoy systems, and coastal installations. With ultra-low energy consumption (average ≤1W) and adjustable transmission power from 1W to 12.5W, it ensures reliable operation without compromising efficiency. A 3-meter high-gain 316 stainless steel antenna provides robust and stable VHF signal coverage, even under harsh conditions.
The lantern supports triple AIS communication modes—FATDMA, RATDMA, and SOTDMA—making it ideal for flexible deployments across different AtoN systems. Visibility is optimized through 256 selectable flash patterns and five adjustable light colors (red, green, white, yellow, blue), ensuring clarity and compliance in varied marine scenarios. With a visibility range of 5–8 nautical miles and a 3-year free replacement warranty, this solution combines performance, adaptability, and peace of mind.
Built for modern navigation needs, it's the perfect blend of efficiency, intelligence, and durability.
