According to Solution Annex ICAO Annex 14 regulations, High Intensity Obstruction Lights (HIOL) should be used to warn the presence of obstacles with an height above 150m or when an aeronautical study indicates such lights as mandatory for the correct warning of an elevated structure, such as chimneys, cranes, buildings, bridges, high tension pylons and other buildings.
High Intensity Obstruction Lights Luxsolar, approved ICAO and EASA, include two type of beacons, with different charactertistics and uses:
- HIOL Type A (intensity 200.000cd, day-mode white flashing; 20.000cd, twilight-mode white flashing; 2.000cd, night-mode white flashing), mainly used on skyscrapers, bridges, etc;
- HIOL Type B (intensity 100.000cd, day-mode white flashing; 20.000cd, twilight-mode white flashing; 2.000cd, night-mode white flashing), mainly used on high voltage pylons where is not practicable install cable markers.
LUXSOLAR offers to its customers also DUAL type beacons in the same light fixture, suitable to be used during the day (with white LEDs) and during the night (with red LEDs); these beacons are:
- DUAL HIOL Type AB (intensity 200.000cd, day-mode white flashing; 20.000cd, twilight-mode white flashing; 2.000cd, night-mode red flashing) should be used in combination with Low Intensity Obstacle Lights, Type B;
- DUAL HIOL Type AC (intensity 200.000cd, day-mode white flashing; 20.000cd, twilight-mode white flashing; 2.000cd, night-mode red steady burning) should be used in combination with Medium Intensity Obstacle Lights, Type C.
