3 – 12 NM

The MBL400S is a medium-range LED sector flashing light, with a great optical efficiency, providing sectored light beams with an accuracy of up to 0.5o. Its luminous source consists of high-intensity LED diodes, obtaining a maximum range of 12 nautical miles.


Intended to be placed in on-shore aids-to-navigation locations, such as poles and towers, as well as hard-to-reach sites or under extreme environmental conditions.

Its optical system utilises the point light source of the lens to make an effective sectorisation in each case. Every sector requires an individual light level, which enables practically any sector configuration.

Levels are superimposed and protected by a shock-resistant glass lens cover. Thus, each beacon is personalized as considering the required range, colours and angles of sector.

Designed according to IALA Recommendations.
