The HA-OSH150-32 and HA-OSH150-50 are precision-engineered low-intensity LED obstruction lights developed to mark obstacles up to 45 meters (150 feet) in height, enhancing airspace safety by alerting aircraft to potential hazards. These fixtures are ideal for marking objects that rise above the obstacle protection surface but remain under the 45-meter threshold, where less extensive lighting solutions are appropriate. In compliance with international aviation safety guidelines, they serve a critical role in minimizing collision risks during nighttime operations.
Each unit is housed in a robust, weather-resistant aluminum enclosure finished in high-visibility yellow (RAL 1021), with chromate conversion and powder coating for added durability. Designed for use in harsh environments, including offshore installations and explosive atmospheres, these obstruction lights meet stringent compliance standards, including ICAO Annex 14 Volume I (Aerodromes), Volume II (Heliports), EASA ADR, UK CAP 168, UK CAP 437, and ATEX/IECEx Zone 2 (II 3 G Ex nA IIC T5) certifications.
Built with advanced LED technology and a borosilicate tempered red Fresnel glass lens, the HA-OSH150 series provides consistent and highly visible output in both Class A and Class B configurations. The light intensity exceeds >10 candela for ICAO Class A and >32.5 candela for ICAO Class B, with optional configurations surpassing 50 candela to meet specific national aviation authority requirements such as those in the Netherlands.
This obstruction light offers exceptional energy efficiency with a typical power consumption of just 5 watts and a long service life of over 75,000 hours, minimizing maintenance and operational costs. Power supply options range from 90–264 VAC (50/60 Hz), making it suitable for a wide variety of global electrical systems. Standard electrical connections include dual M20 cable glands for easy integration.
Operational versatility is enhanced with optional flashing modes at 30, 60, 90, or 120 flashes per minute, which can be set at the factory based on project needs. The compact footprint of 160 x 244 x 150 mm and a weight of 4.2 kg allows for flexible mounting in confined or challenging locations, while its IP66 ingress protection ensures reliable operation in temperatures ranging from -40°C to +60°C.
Whether installed on industrial structures, offshore platforms, helidecks, or other aviation-sensitive environments, the HA-OSH150-32 and HA-OSH150-50 offer a compliant, durable, and energy-conscious lighting solution for obstacle marking below 45 meters.
