The high-intensity aviation obstruction light consists of a 155mm diameter beacon lens, an aluminum alloy cast lamp holder, a microcomputer chip integrated circuit controller, and an imported long-life pulse xenon lamp. It can produce extremely strong flash at an instant. The 155mm diameter monocone lens is a Fresnel lens injection-molded from polyacrylic plastic. When the lamp is focused, the lens can focus, which can greatly increase the intensity of light and expand the angle of emission. GZ-155B aviation obstruction light has automatic daylight control switch function. It automatically turns off during the day and automatically turns on at night or on cloudy days.
