The Obelux medium-intensity stand-alone obstruction light model delivers a powerful 20,000 candela white flashing output alongside a 2,000 candela red fixed or flashing option. Designed specifically for marking tall structures such as wind turbines, transmission masts, chimneys, and broadcast towers, this versatile lighting solution ensures high visibility and safety compliance across a variety of critical infrastructures. The unit integrates advanced features including fault monitoring, a built-in photocell for automatic day/night operation, and GPS synchronization for precise flash timing coordination. It supports both standalone operation and Modbus communication, allowing it to function as part of the larger Obelux aviation lighting network.
Optically, the light offers a full 360° horizontal beam and a narrow vertical beam of 3°, optimized to provide clear, concentrated visibility from all directions. The maximum intensity at -1° elevation does not exceed 11,250 candela for the white light and 1,125 candela for the red light, ensuring adherence to aviation safety regulations, while the intensity at -10° remains under 750 candela (white) and 75 candela (red). Optional NVG-compliant infrared (850 nm) output is available, providing compatibility with night vision goggles for specialized operational environments.
This medium-intensity light complies with a wide range of international regulations. It meets ICAO Annex 14 Volume 1 (8th Edition, July 2018) standards for Medium-intensity Type A and Type B/C lights, aligning with recommendations outlined in Table 6-3 of the annex. Additional compliance includes FAA specifications under Advisory Circular AC 150/5345-43J for obstruction lighting equipment, French DGAC regulations, Transport Canada CAR 621 standards, and Spanish AESA regulations. This broad certification portfolio highlights the light’s suitability for global aviation safety applications.
Constructed with durability in mind, the device features a painted marine-grade aluminum housing designed to withstand harsh offshore and onshore environments. Its glass cover and IP66-rated protection ensure robust defense against dust and water ingress. The unit operates reliably across a wide temperature range from -40 °C to +55 °C. Physical dimensions include a height of 412 mm, a length of 280 mm, and mounting provisions compatible with 240 x 240 mm surfaces using Ø17 mm holes. The light weighs approximately 14 kg and is equipped with M25 cable glands accommodating cables from 11 to 17 mm in diameter, with seals for smaller cables also provided.
Electrical specifications include wide input voltage ranges: AC operation accepts 90 to 265 VAC at 50 or 60 Hz, while DC models function within 20 to 60 VDC. Flash rates are selectable at 20, 30, 40, or 60 flashes per minute. The device meets EMC emission and immunity standards EN 61000-6-4 and EN 61000-6-2, respectively, and incorporates built-in overvoltage protection for enhanced reliability. An alarm relay with dry contact outputs (normally open/closed) is included, supporting switching up to 50 VDC at 1 A or 250 VAC at 6 A. Communication capabilities include isolated Modbus RS-485.
Power consumption varies based on mode and configuration. AC versions typically draw 19 W during daytime flashing at 40 FPM (white light), with reduced consumption of 4 W at night under the same flash rate. Night mode with infrared enabled increases power usage modestly. Red light operation ranges from 17 W (flashing) to 30 W (fixed light with IR) in night conditions. These energy profiles balance bright visibility with operational efficiency.
Optional features include a cold-climate version tailored for extremely low temperatures, NVG-compliant infrared output, and various add-on interface cards such as a 4 input/4 output (I/O) interface, Ethernet connectivity via RJ-45, and a 4-port network switch supporting both RJ-45 and fiber optic connections. These options enhance the light’s integration capabilities within complex aviation lighting systems or facility management networks.
In summary, the Obelux medium-intensity 20,000cd white and red obstruction light offers a robust, regulation-compliant, and technologically advanced solution for marking tall structures worldwide. Its comprehensive feature set, rugged construction, and flexible operational modes make it an ideal choice for aviation safety in demanding environments, including offshore wind farms and critical infrastructure sites.
