L-864
Flashing Red Beacon

This steady or flashing red LED beacon obstruction light is the perfect solution for wind turbines, towers (cell/broadcast/other), buildings, and similar obstructions. Meets FAA and ICAO standards. Available with IR option for night vision. Easily retrofits to replace incandescent light. Uses only 48W. Comes with a 5-year warranty.

Applications

The FAA advises that steady red obstruction lights be used on towers and communication obstructions from 50–2,200 ft. in height, which can pose a danger to small planes and helicopters at night. Steady red obstruction lights are advised up to 150 ft. in height, medium intensity flashing red or white lights up to 350 ft. high, and several levels of lights up to 1750 ft. See the FAA Advisory.

The D464 Series LED based medium intensity red beacon utilizes state-of-the-art optical design to achieve the most compact, efficient, FAA compliant L-864 device in the market. It is ideal for new installations and retrofits of incandescent lights on cell towers, broadcast towers, wind turbines, tall buildings, and similar obstructions.

The D464 can be either steady red or flashing. It is also available with our Infrared Option for visibility to pilots using night vision (see below). The beacon’s robust, low power design will provide years of maintenance-free service. Uses only 48W. Comes with a 5-year warranty and has a typical operating lifetime approaching 15 years.

Infrared (IR) Option

Night Vision Goggles (NVGs) and Aviator’s Night Vision Imaging System (ANVIS) often employ Class A, B, and C filters. These filters can reduce LED sources that emit light in the visible spectrum. The Infrared (IR) option for RTO lights overcomes this obstacle by combining visible red LEDs and IR LEDs in a single unit.

FAQs

What is the difference between an L-810 marker light and an L-864 Beacon?
L-810 marker lights are smaller obstruction lights built for structures with low profiles. The L-864 red beacon light is a medium intensity light built for towers or structures 150ft. or taller. The larger design on the L-864 red becon gives off a larger light profile to ensure visibility of obstructions.

Do I ever need both L-810 and L-864 beacons on the same structure?
Only towers within the 150-350ft. range require both. One L-864 beacon on top and two mid level L-810 markers lights.

Is flashing required?
Towers with flashing red LED lights, or in certain cases white flashing lights, are required to meet all Avian FAA lighting guidelines.
