WM-RB500 Marine Revolving Beacon

The WM-RB500 revolving beacons are designed to meet various lightbeacon and lighthouse applications providing an effective range of up to 33 nautical miles at transmissivity factor (T) of 0.85, depending on the intensity of the lamp used.

The compact, rugged and heavy duty WM-RB500 rotating beacon housing is made of corrosion-resistant, cast aluminium alloy material that holds a toughened, UV-stabilized acrylic fresnel lens cover.

The bottom driven 6-panel lens cage configuration supports WM-Patent design "bullseye" optic lenses that are moulded from optical-grade acrylic resin.

The lens cage is rotated by a highly reliable stepper-motor drive system providing sufficient torque to rotate the assembly while consuming a maximum current of 200mA. Rotational speeds are factory set to customer requirements.

The preprogrammed rotational speeds is field selectable from 0.5 to 6 RPM by means of an InfraRed programmer unit, or by adjusting two HEX switches on the motor controller PCB. Higher rotational speeds can also be incorporated when needed.

The 6-panel lens arrangement produces six regularly spaced flashes in one revolution. Blanking panels are inserted at respective slots for various group flashing.

The WM-RB500 is equipped with WM-FL100 6-place automatic control lampchanger. Access to the lamp replacement can be conveniently made through a removable panel at the top cover.

Coloured flashes are easily achieved by using respective coloured acrylic lens cover. Clear, red, green and yellow (amber) colours, in accordance to IALA preferred colour chromaticity regions, are available.



The WM-RB500 is primarily designed and suitable for use as:-

  • long range landfall beacon
  • marking marine hazards
  • entrances to ports and harbours
  • crucial turning point in precautionary areas
  • lighthouse beacon
  • offshore lightbeacon

Standard WM-RB500 Revolving Beacon has ingression protection up to IP67. Appropriate measures have been considered and implemented in regards to the heat ventilation from the housing.
