F865 medium intensity white beacon AC system consists of a 48VDC F865 flash head and a 480W power converter box.

The 48VDC F865 light head can operate range from 24VDC to 48VDC. Incorporated a microcontroller, it flashes white light 20,000 candelas at daytime automatically dims to 2,000 candelas at nighttime. F865’s LED module consists of 56 OSRAM super-power white LEDs. The optical design ensures the effective intensity and spread beam meet the criteria of FAA L-865 and ICAO medium intensity type A.

The 480W converter box is capable of converting universal AC (90-264VAC) to 48VDC for powering the F865 48VDC light head. F865 AC system is an ideal solution where the power module can be easily accessible to be maintained.

F865 medium intensity LED obstruction light can work independently with self-controlled configurations (e.g., built-in photocell, flashing program, GPS) as an economical solution. In a central controlling and monitoring system, a CB3 control box can connect multiple levels of F865 beacons to achieve synchronous or sequential flashing.

The white medium intensity obstruction light is usually used for unpainted structures over 105m, such as radio and TV towers, chimneys, cooling towers and skyscrapers.
