F864 is an ICAO certified red LED medium intensity obstruction light (2000cd + 25%). It complies with ICAO Obstacle Lighting medium intensity type B and FAA L-864 under flashing mode. It also complies with ICAO Obstacle Lighting medium intensity type C when steady burning.

F864’s photometric part consists of 28 pcs of ultra-bright OSRAM LEDs and efficient Fresnel Lens. This optical design ensures the effective intensity and spread beam meet the criteria of ICAO and FAA.

F864 medium intensity obstruction light is equipped with an aluminum column inside and a heatsink on top for enhanced thermal cooling. The straight fin arrangement of the heatsink maximizes airflow to optimize heat dissipation performance and stability.

The red medium intensity obstruction lights are usually installed on towers, buildings, cranes, chimneys, windmills and other tall structures over 45 meters. It can work independently with self-controlled configurations (e.g., built-in photocell, alarm relay, flasher) as an economical solution. In most cases, one or more F864 medium intensity aviation warning lights group with multiple levels of low intensity obstruction lights as a system, controlled and monitored by a control box.
