The low-intensity obstruction lights are divided into two categories based on their application. The first category includes Type A(intensity 10cd, red, steady burning), Type B(intensity 32cd, red, steady burning), and Type E(intensity 32cd, red,flash) for marking fixed obstacles. These lights are used to mark obstacles below 45m(147 feet) in height, ensuring aviation safety. The second category is designed specifically for ground-moving obstacles at airports, primarily providing warnings at twilight and night. Type C (intensity 40cd, yellow or blue, flash) and Type D(intensity 200cd, yellow or blue, flash). The design of low-intensity obstruction lights aims to minimize light pollution while ensuring aviation safety. Nanhua Electronics offers a wide range of models to meet various national and regional aviation standards.
