As specified by Annex 14 of ICAO regulations, Low Intensity Obstruction Light can be used to warn the presence of obstacles up to 45m height, such as telecommunication towers, wind turbines, chimney, cranes, buildings and other structures.
This beacon is the simplest device according to ICAO standards. It provides steady burning red light with two types of intensity: ≥10cd for Type A, ≥32cd for Type B and ≥32cd for Type E (flashing red light).
Le luci a bassa intensità si suddividono in:
Low intensity obstacle lights, Type A (intensity >10cd, red steady burning) can be used alone.
Low intensity obstacle lights, Type B (intensity >32cd, red steady burning), can be used either alone or in combination with medium intensity obstacle lights Type B, Type AB or with high intensity obstacle lights Type AB.
Low intensity obstacle lights, Type E (intensity >32cd, red flashing), can be used either alone or in combination with medium intensity obstacle lights, Type B. Type E will flash at the same rate of other flashing beacons installed.
