The M650 offers up to 60 cd IALA peak intensity within a compact, lightweight yet durable design. With intelligent energy management systems and an intuitive on-board user interface, the M650H provides a practical solution for marinas, docks, barges, bridges, and more. Also available with GPS functionality as well as the option to be configured with Sequential Flashing, the M650 is one of the most advanced and durable lanterns available today in its class. It is well proven with over 50,000 being sold worldwide since being introduced in 2009.

  • 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.
  • NEW -  Now available with optional "Sequential Flashing " or "Running Light" function. Requires GPS Version of M650H. See here for more details
  • Life expectancy 15 years; 3 year warranty
  • Made in the USA
