Medium intensity aviation obstruction lights are aviation obstruction warning lights that comply with the relevant standards of the International Civil Aviation Organization (ICAO) and the Federal Aviation Administration (FAA).
This type of LED aviation obstruction light is mainly suitable for towering or critical facilities such as towers, chimneys, high-rise buildings, large bridges, and large port machinery to enhance the visibility and safety of these facilities at night.
The light source of medium-intensity obstruction lights usually uses high-brightness LEDs, with red or white luminous color options, and can withstand different operating voltages and environmental conditions.
