The Obelux medium-intensity stand-alone red obstruction light, delivering 2,000 candela, is specifically designed for marking tall structures such as wind turbines, transmission masts, chimneys, broadcast towers, and bridges. Engineered to perform reliably under demanding offshore conditions, this light is ideal for use in offshore wind turbines and other critical maritime infrastructure. It incorporates advanced features including integrated fault monitoring, an automatic photocell for day/night operation, GPS synchronization for precise flash timing, and a cold climate version equipped with a thermostat-controlled heater to maintain optimal performance in low-temperature environments. The light supports both stand-alone use and integration into larger lighting systems via RS-485 Modbus communication as part of the Obelux aviation light system network.
Optically, the light produces a 2,000 candela aviation red flashing output, meeting FAA L-864 and L-885 specifications with flash rates of 30 or 60 flashes per minute depending on the model. The horizontal beam covers a full 360 degrees, ensuring maximum visibility around the structure it marks. The light is compliant with FAA Advisory Circular AC 150/5345-43J, issued March 11, 2019, which governs specifications for obstruction lighting equipment.
Key features of this medium-intensity aviation red obstruction light include support for both stand-alone operation and RS-485 Modbus network communications, making it flexible for different control environments. The built-in GPS synchronization enables multiple lights to flash in unison, which is critical for aviation safety. The photocell automatically switches the light on and off according to ambient light conditions, optimizing energy use. The cold climate version (CCV) includes a smart 15W thermostat-controlled heater designed to extend the product’s life and ensure functionality in cold environments, with input voltage monitoring that disables the heater to protect battery life when voltage drops below a set threshold. The light also features a dry contact alarm relay for fault detection and a visibility sensor interface allowing adaptive luminous output levels of 10%, 30%, and 100%, improving efficiency in varying weather conditions. An embedded web server provides easy configuration and monitoring. Additionally, the light is designed for easy chaining of multiple units via power and data cables without the need for a junction box.
Electrically, the obstruction light operates on a nominal voltage range of 100-240 VAC at 50/60 Hz with a tolerance of ±10% and ±6% respectively. It also supports DC operation across two voltage ranges: 10-30 VDC and 20-60 VDC. Flash rates can be selected among 20, 30, 40, or 60 flashes per minute to meet different regulatory requirements. The product complies with electromagnetic compatibility standards EN 61000-6-4 for emissions and EN 61000-6-2 for immunity. Robust overvoltage protection of Type 2 is built in, using varistors across line-to-protective earth, neutral-to-earth, and line-to-neutral. The alarm relay output provides normally open or normally closed dry contact switching rated for 50 VDC at 1 amp or 250 VAC at 6 amps, ensuring reliable fault signaling. The isolated Modbus RS-485 interface allows seamless integration into lighting control networks.
Mechanically, the light is constructed with a durable anodized marine-grade aluminum body and end parts, with AISI 316 acid-proof stainless steel screws ensuring corrosion resistance in harsh environments. The light features a tough glass dome with an ingress protection rating of IP66, protecting it against dust and powerful water jets. It operates reliably across a temperature range from -40 to +55 °C, both in storage and active use. The physical dimensions are 347 mm in height, 180 mm in width, and 160 mm in depth, with a weight of 4.3 kg excluding the mounting set. Cable glands include two M25 glands suitable for cables with diameters from 11 to 17 mm (with rubber seals for smaller 6-13 mm cables) and two M20 glands for cables from 6 to 12 mm. The design supports easy chaining of multiple lights through both data and power cables without requiring an external junction box, simplifying installation and maintenance.
Overall, the Obelux FAA medium-intensity L-864/L-885 2,000cd red obstruction light combines robust construction, advanced features, and flexible network integration to provide reliable, high-visibility marking for critical tall structures, particularly in challenging offshore environments.
