Up to 4 Nautical Miles

Features & Benefits


  • Range up to 2 NM
  • NEW GPS synchronized flash option
  • Up to 60 candela IALA peak intensity
  • Available in all IALA chromaticity colours
  • Intelligent deployment location settings protect against improper configuration
  • Intuitive on-board user interface, infrared remote and software programmability
  • Replaceable and recyclable battery pack


  • Unprecedented Reliability: microprocessor Energy Management System (EMS) monitors and adapts the light to environmental conditions for consistent operation and long life under the toughest conditions.
  • Designed and tested to the toughest industrial standards: immersion, shock and vibration, corrosion, solar radiation, chemical resistance, hail and EMC/EMI/ESD. See spec sheet for test information.
  • Intelligent settings: the first solar product to incorporate intelligent deployment location settings that allow the M650 to be tuned to its location, protecting it against improper configuration. Lantern automatically adjusts for Schmidt-Clausen.
  • Self-contained and low maintenance: all components are incorporated within a compact, stand-alone unit for easy deployment and relocation. A replaceable battery pack extends service life beyond five years, reducing total cost of ownership and resulting in significant cost savings.
  • Green solution: a clean, renewable and reliable energy source with the lightest environmental footprint. Recyclable batteries and RoHS compliant.
