The WM-BL140SP6 assembly is a completely self-contained lantern that is compact, lightweight and rugged, and requires the least or virtually no maintenance throughout its operation.
The optical system utilises WM-Patent designed UV-stabilized acrylic optic lens and with a choice of up to 3-tiers of the highly efficient, high intensity LED array, OR 2-tiers with integrated optional feature(s). It has an effective range of up to 6.1 nautical miles at a transmissivity factor of T=0.74 or 8 nautical miles @ transmissivity factor of T = 0.85 (with the use of Hi Power LEDs and increased number of tiers to achieve upto 12 nautical miles @ transmissivity factor of T = 0.85).
The housing is constructed from material of toughened polycarbonate resin and the base is of marine graded aluminium alloy (painted to respective colour of identification). The unit houses up to 26AH capacity of sealed, maintenance-free battery. The assembly consists of 6 nos. of 3W high efficiency, monocrystalline solar modules.
The WM-BL140SP-6 is preprogrammed with up to 256 field selectable flash codes and changing the flash character can be easily done by using an Infrared programmer unit.
The WM-BL140SP-6 self-powered LED lantern has a wide vertical divergence and is primarily designed for installation on fixed structures, buoyant beacons and navigation buoys in all areas.
