    Sealite SLC420Sealite Compact 4-5+ Nautical Mile Range  - Solar Flashing Marine Lantern - Model SLC420

    The SLC420 is a robust, completely self-contained 4-5nm+ Solar LED Marine Lantern which incorporates a 36 LED light source for even greater light intensity. The 3 & 4 hole bolt pattern base fits directly onto existing 200mm OD industry standard mounts for ease of installation.

    The chassis of the SLC420 is made from cast aluminum, subject to 7-stage powder-coating in high visibility IALA colors for daytime recognition, with UV-stabilized rubber corners and gaskets providing a superior IP68 waterproof rating - the best in the industry.

    Four (4) premium-grade solar modules are integrated into the assembly, and mounted to collect sunlight at all angles.

    The unit is capable of producing any of 256 IALA recommended flash characters - field-adjustable without the need for ancillary equipment.

    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.


    36 ultra-high intensity LEDs
    3 & 4 hole bolt pattern on 200mm OD base for ease of installation
    4x 5watt (20watt total) multi-crystalline solar modules, ensuring 
       maximum light collection to charge the battery
    Internal 24Ah battery - user replaceable
    Robust 7-stage powder-coated aluminum chassis with rubber 
       extruded corners
    Automatic night activation
    Simplicity of design ensures ease of maintenance in the field
    Heavy-duty aluminum construction
    All components user-replaceable in the unlikely event of damage
    256 IALA flash patterns
    Tempered glass solar modules for peak efficiency
    IP68 waterproof & full 3 year warranty

    Optional Flash Synchronization via RF Comm Sync (SLC420-CS) or GPS (SLC420-GPS)

    The SLC420 may be fitted with optional comm sync RF module for short range flash synchronization (SLC420-CS). For flash synchronization of lanterns installed over longer ranges, a GPS module may be fitted (SLC420-GPS).

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

    Optional GSM Remote Monitoring & Control (SLC420-GSM)
    The SLC420 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 Remote Radio Control (SLC420-RC)
    Radio control may be fitted to the SLC420 model enabling users to remotely modify the setup of their lantern via handheld radio controller (SL-RC-2.4).
