The Obelux IR850-048-CST infrared LED obstruction light is a high-performance, military-certified lighting solution designed specifically for aviation obstacle marking in environments requiring Night Vision Goggle (NVG) compatibility. Operating at the 850 nm infrared wavelength, this obstruction light complies with the Ministry of Defence (MOD), UK standards, meets ICAO Low-Intensity Type B (32 candela) requirements, and is fully compliant with FAA L-810 specifications. Certified by the MOD UK, it is engineered for precision, reliability, and durability in demanding applications such as wind turbines and other aviation obstacles.
This obstruction light emits a 360-degree horizontal radiation pattern and a vertical beam spread of -15° to +30°, ensuring maximum coverage and visibility for NVG-equipped pilots. The typical radiometric intensity is 300 mW/sr, and the output is stabilized through a constant current generator, maintaining consistent performance regardless of input voltage fluctuations. The LEDs are configured in multiple independent groups to enhance reliability and longevity, delivering an expected lifetime exceeding 100,000 hours without significant output degradation.
Electrically, the light operates on a nominal 48 VDC power supply, with an input range of 44–54 VDC. It consumes just 15 watts of power under constant current operation, while in flashing mode (60 flashes per minute, 250 ms duration), the average power draw is under 4 watts, offering energy-efficient performance and significantly lower lifetime costs. This low power consumption translates to extended maintenance intervals and reduced operational expenses.
Constructed from black anodized aluminum, the light unit is built to withstand harsh environmental conditions, featuring marine-grade protection with a sealed borosilicate glass lens and an IP65 ingress protection rating. It comes equipped with a galvanized steel mounting arm, acid-proof U-bolts, and hex nuts for secure installation. The operating temperature range spans from -55°C to +55°C, making it suitable for extreme climate zones. The compact form factor—170 mm in height and 140 mm in diameter—combined with a total installed weight of 3.3 kg, ensures ease of integration on various structures.
This light is designed for use with external flash controllers, such as the PCFL-DC1-TB, which combines photocell and flash control functions, or the CSW-DCW-8+2-F, which adds fault monitoring capabilities. These options enhance system versatility and automation for both day/night operation and maintenance diagnostics.
The Obelux IR850-048-CST is ideal for wind farms, communication towers, and any aviation obstruction requiring NVG-compatible infrared marking. With certification to MOD CAS-AS LFOS (WITT/605/LFOPS, 17 Dec 2010), long service life, and low total cost of ownership, it offers a dependable and regulation-compliant solution for mission-critical airspace safety applications.
