2-3NM Solar Marine Lantern (SL-70)

The Sealite Solar Marine Lantern Type SL-70 is exceptional in its unique ability to be able to ‘track the sun’ and operate reliably in low sunlight conditions. The Solar Marine Lantern Type SL-70 has been proven to operate as a 2-3+ nautical mile compact buoy lantern in various low sunlight environments such as Britain, Canada and Europe.

Made from tough, durable polycarbonate and using the latest high intensity LEDs, the SL-70 lantern boasts dual high-performance solar modules. These solar modules are angled to obtain maximum sunlight capture, allowing the unit to operate reliably in a range of low sunlight environments.

The SL-70 can be installed in minutes and requires no operator intervention. The flash characters are easily adjusted onsite by the user, and the lantern has a permanent ON/ OFF switch for easy storage.

The SL-70 comes with standard rotary switches for convenient in-field changes of flash characters and intensity selection. In addition, the unit may be provided with an IR programmer for added functionality. Programmable features include; flash code adjustment, battery diagnostics and lux adjustment.

Optional GPS Synchronisation

The SL-70 is available with optional GPS Synchronisation. Two (2) or more lights can be synchronised to flash in unison via an internal GPS module. 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 Light Configuration

In high sunlight regions, the SL-70 intensity settings may be increased to provide a range of >3 nautical miles (colour dependant).

Optional Larger Battery Pack

In regions where additional autonomy is required, the SL-70 can be supplied with a larger 16Ah battery pack – this greatly extends the operational autonomy.
