AH-MI/B Medium-intensity Type B Aviation Obstruction Light


Medium-intensity Type B Aviation Obstruction Light used in Tower Crane, Wind Turbine, High Mast, Metallurgic, Towers(Telecom, GSM, Electric), Smokestacks, High-rise Buildings and any other potentially hazardous obstructions between 45m and 105m to air traffic with a flashing red safety light.



1.Good impact protection strength, thermal stability, high transmittance.
2.Built-in circuit protect LED, extremely reliable and cost saving.
3.Shockproof and corrosion resistant. Working environment temperature: -40℃ ~ +60℃.It can be used in very poor conditions. 
4.LED is special red color for Aviation Obstruction Light. Typical LED lifetime is more than 100,000 hours. 
5.Resistant to heavy rain or storms and corrosion.
6.Free maintenance and aluminum alloy material.
7.95% less power consumption than incandescent light.
8.Dawn to Dusk operating: Built-in photocell can let light work automatically at night, closed during the day.
