2-3NM Solar Marine Lantern (SL-60)

2-3NM Solar Marine Lantern (SL-60)

The Sealite 2-3NM Solar Marine Lantern (SL-60) is the world’s most popular and versatile 2-3NM+ solar marine light.

The SL-60 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-60 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, lux adjustment, ON/OFF and hibernation mode.

Optional GPS Synchronisation

The SL-60 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 200mm Bolt Pattern Base

The SL-60 is available with optional large 200mm bolt pattern to suit installation requirements.

Optional Larger Battery Pack

In regions where additional autonomy is required, the SL-60 can be supplied with a larger 8Ah or 16Ah battery pack – this greatly extends the operational autonomy.
