The Obelux high-intensity stand-alone white light with a luminous intensity of 50,000 cd, alongside its medium-intensity red 2,000 cd model, is specifically designed for marking tall structures such as wind turbines, transmission masts, chimneys, and broadcast masts. These lighting solutions utilize advanced LED technology to deliver reliable, high-performance illumination suitable for challenging environments, including offshore installations. Both models are equipped with innovative features that enhance operational flexibility and safety, making them ideal for use as part of the Obelux aviation light system network. They support stand-alone operation as well as Modbus communication, enabling seamless integration into broader lighting control systems.
Among the key features of these lights is the incorporation of fault monitoring and an integrated photocell, which allows automatic adjustment based on ambient lighting conditions. GPS synchronization is built in to ensure precise timing and coordination with other lighting units, especially important in aviation safety applications. The lights also include a hot start feature designed for radar-controlled systems, allowing rapid and reliable activation when required. The luminous output is adjustable across three levels—10%, 30%, and 100%—providing adaptability to various visibility and regulatory needs. Additionally, these lights comply with NVG (Night Vision Goggles) standards by incorporating infrared output at 850nm. Designed for durability, the Obelux lights have a design lifetime exceeding 20 years and come with an industry-leading 5-year warranty.
Optically, the white light produces an intense 50,000 candela output during daytime, reducing to 10,000 cd at twilight, and 2,000 cd at night, while the red model operates at 2,000 cd fixed or flashing depending on configuration. The infrared output operates at 850nm wavelength, suitable for NVG use. The lights emit a full 360-degree horizontal radiation pattern and a narrow vertical beam angle of 3 degrees, ensuring highly visible marking of tall structures from all directions.
The design complies with guidelines established by Traficom Finland, ensuring it meets rigorous aviation safety standards. Electrical specifications include a nominal operating voltage range of 100 to 240 VAC ±10% at 50Hz/60Hz, with an extended voltage range from 90 to 265 VAC. For DC operation, the voltage range is 20 to 60 VDC. Flash rates are configurable with options of 20, 30, 40, or 60 flashes per minute. The product meets electromagnetic compatibility standards EN 61000-6-4 for emissions and EN 61000-6-2 for immunity, and features overvoltage protection. An alarm relay output is provided with normally open (NO) and normally closed (NC) dry contacts, rated for switch voltages up to 50 VDC at 1 A or 250 VAC at 6 A. Communication over Modbus RS-485 is electrically isolated for robust integration into control networks.
Mechanically, the Obelux light is constructed with a marine-grade aluminum body painted to C5MHigh standards, ensuring excellent corrosion resistance for offshore and harsh environments. The enclosure includes a durable glass cover and offers a high ingress protection rating of IP66, guaranteeing resistance against dust and powerful water jets. It operates reliably in extreme temperatures ranging from -40 to +55 °C. The mounting interface consists of a 240x240 mm base plate with Ø17 mm holes for secure installation. The light itself measures 412 mm in height and 280 mm in length, making it compact yet highly visible for its intended marking applications.
