The WM-BL140SP-4 assembly is a completely self-contained lantern assembly that is compact, lightweight and rugged, and requires the least or virtually no maintenance throughout its operation.
The optical system utilises WM-Patent designed, field proven UV-stabilized 150mm acrylic optic lens and with a configuration of up to 3-tiers of the highly efficient, high intensity LED array, OR 2-tiers with integrated optional feature(s). It has a maximum effective range of up to 7.0 nautical miles at a transmissivity factor of T=0.74.
The housing is constructed from material of toughened polycarbonate resin. The unit houses up to 30AH capacity of sealed, maintenance-free battery pack. The assembly consists of 4 high efficiency, mono-crystalline solar modules totaling up to 20Wp.
The WM-BL140SP-4 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-4 compact self-contained LED lantern has a wide vertical divergence and is primarily designed for installation on fixed structures, buoyant beacons and navigation buoys in all areas. The WM-BL140SP-4 can be coupled with optional features including AIS AtoN ready.
