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.
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 units group with multiple levels of low intensity obstruction lights as a system, controlled and monitored by a control box.
