The SLC410 is a robust, completely self-contained 3–5nm+ Solar LED Lantern specifically designed to withstand the tough marine environment, providing years of reliable, low-maintenance service. The 3 & 4 hole bolt pattern base fits directly onto existing 200mm OD industry standard mounts for ease of installation.

The SLC410 has a large power supply consisting of four 5watt panels (20 watt total) making this model perfect for use in lower sunlight areas or where more demanding duty cycles are required. The four (4) premium-grade solar modules are integrated into the assembly, and mounted to collect sunlight at all angles.

The base and top of the SLC410 are made from cast aluminium, subject to 7-stage powder-coating in high visibility IALA colours for daytime recognition, with UV-stabilised rubber corners and gaskets providing a superior IP68 waterproof rating – the best in the industry. The SLC410 has a handle incorporated into the chassis for safe lifting.

The tough, polycarbonate lens is specifically designed for use with LEDs and incorporates an environment-friendly spike – deterring unwelcome bird life. The lens design also ensures that vessel operators clearly see the light from above when passing the AtoN.

The SLC410 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.

GPS Synchronisation NOW fitted as Standard

Sealite has utilised the latest advancements in GPS technology to develop an internal synchronisation system that can be incorporated into the SLC410 lantern. Using overhead satellites, lights set to the same flash pattern will flash in unison.

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.
