Aviation obstacle lights can be classified in low intensity aviation obstacle light, medium intensity aviation obstacle light and high intensity aviation obstacle light, according to their light intensity. The low intensity aviation obstacle light is applicable to 45 meters and below. The medium intensity aviation obstacle light is applicable to 150 meters and below. And the high intensity aviation obstacle light is applicable to 150 meters and above.
1. Low intensity aviation obstacle light
(1)Low intensity aviation obstacle light Type A: red steady burning, light intensity>10cd.
(2)Low intensity aviation obstruction light Type B: red steady burning, light intensity>32.5cd.
(3) Low intensity aviation obstruction light Type C: yellow or blue flashing, 60-90 times/minute, light intensity>40cd.
(4) Low intensity aviation obstruction light type D: yellow flashing, 60-90 times/minute, light intensity>200cd.
2. Medium intensity aviation obstacle light
(1) Medium intensity aviation obstruction light type A: white flashing, light intensity 20000cd, 105m-150m.
(2) Medium intensity aviation obstacle light type B: red flashing, light intensity 2000cd, 105m below.
(3) Medium intensity aviation obstacle light type C: red steady burning, light intensity 2000cd, 105m or less.
3. High intensity aviation obstacle light
(1) High intensity aviation obstruction light Type A: white flashing, 40-60 times/minute, light intensity 2000-200000cd, 150m or more.
(2) High intensity aviation obstruction light type B: white flashing, 40-60 times/min, light intensity 2000-100000cd, 150m or more.
