The Sealite SL125 LED marine lantern is maintenance-free and used by many of the world’s busiest ports and largest militaries. The lantern is available with up to 4 tiers of 36 LEDs (144 LEDs in total), for complete flexibility to suit every application.

SL125 Technology
The SL125 is the most advanced LED marine lantern on the market. Utilising the latest software and microcircuitry developments, the lantern boasts a huge number of features including flash-memory and the most efficient power conversion available.

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

The unit is sealed using polycarbonate bonding compounds similar to those used by major automobile manufacturing companies. This also enables a waterproof rating of IP68 - unmatched by other manufacturers.

Lantern Operation
The SL125 is ideal to fit on existing structures, or can be supplied as a complete unit with external solar modules and battery compartment.

The large industry-standard base, and 1 metre of included cable allows the SL125 to be readily fitted to any 12 volt power supply.

Once installed, the SL125 requires no operator intervention. The flash characters are easily adjusted on-site by the user, and the lantern will automatically begin operation at dusk - once the ambient light threshold drops sufficiently.

Up to 4 tiers of 36 LEDs are available to increase the light intensity of the SL125 unit.

The SL125-2, SL125-3 and SL125-4 have 72, 108 and 144 LEDs respectively.

Each LED tier utilises the Sealite omnidirectional LED Reflector (US Pat. No. 6,667,582. AU Pat. No. 778,918) to increase the intensity and uniformity of the horizontal output.

Multiple focal points on the lens then create superior divergence specifications to suit regulations worldwide.
