The L92-XXX-E is Orga’s low intensity tower light specifically designed for the offshore wind industry. This red LED obstacle light marks the tower of a wind turbine at night. The light fixture is equipped with a main and standby LED light source and is positioned on the outside of the tower, where its power supply is mounted inside the tower to provide easy access. Designed with smart LED technology including IR and robust due to its sealed housing.
