3-5NM Solar Marine Lantern (SL-C310 Series)

The 3-5NM Solar Marine Lantern (SL-C310 Series) are robust, completely self-contained 3-5NM+ Solar LED Lantern marine lanterns. They are designed to be maintenance-free, installed in minutes, and have a service life of over 12 years. These lanterns are available in three chassis size configurations; compact, standard and extended. They accommodate larger battery capacity and additional solar charging capability. Satellite connectivity is available as an option.

The four (4) premium-grade solar modules are integrated into the assembly, and mounted to collect sunlight at all angles. The lanterns are IP68 water ingress rated wotj a handle incorporated into the chassis for safe lifting.

The SL-C310 series is available with GPS Synchronisation as standard. Two (2) or more lights can be synchronised to flash in unison via an internal GPS module. The SL-C310 series may also be fitted with Satellite Communications Module or GSM Module – enabling users to access real-time diagnostic data and two-way monitoring and control through the Star2M® portal.
