The MDL are long-range LED leading lights, especially designed to mark port approaching and entrance channels. They are normally used in traditional leading stations of two lights, in both day and night modes.


The MDL light produces an unidirectional beam with a horizontal divergence of 10°. Its luminous source, consisting of high-power LEDs of 100,000 hours average life, makes it a maintenance-free beacon.

Manufactured with high quality and resistant materials, the MDL provides a long service life under severe marine conditions.

This lantern strictly complies with IALA Recommendations.
