The SLC600, one of the world’s largest self-contained LED lanterns, is a 6–9nm+ Solar LED Marine Lantern designed for a range of low-maintenance applications. The large solar array makes this lantern perfect for low sunlight regions.

The light boasts a large internal battery compartment, a multiple tiered SL125 LED light-head and 4 premium-grade 20watt solar modules mounted to collect sunlight at all angles.

The SLC600 is moulded from UV-stabilised, virgin polyethylene, providing enormous impact and weather resistance, in addition to high visibility IALA colours.

The tough polycarbonate lens is specifically designed for use with LEDs and also enables vessel operators clearly see the light from above, when passing the AtoN.

The user-friendly, 2-piece design allows the lantern to be opened for convenient battery inspection or replacement whilst the base remains fixed to the supporting structure.

Optional RF Synchronisation or GPS Synchronisation

The SLC600 may be fitted with an optional RF Synchronisation module for short range flash synchronisation. For flash synchronisation of lanterns installed over longer ranges, a GPS module may be fitted.

When lanterns flash in synchronisation they can be clearly distinguished from other navaids and confusing background lighting – ideal for rivers, marina entrances, channel marking and aquaculture.

Optional GSM Monitoring & Control System

The SLC600 may also be fitted with GSM Remote Monitoring and Control capabilities – enabling users to access real-time diagnostics data and change lantern settings via cell-phone or PC interface.

Optional AIS Remote Monitoring

AIS integration enables remote monitoring of the SLC600 as well as crucial message 21 information to be broadcast to mariners within the region.
