The AV-OL-LI is a cutting-edge low-intensity obstruction light engineered to meet the latest FAA and ICAO standards for aviation safety. Certified under FAA AC150/5345-43J and ICAO Low Intensity Types A, B, and E, the AV-OL-LI is purpose-built for marking obstructions up to 150 feet (45 meters) above ground level. With the increasing importance of night vision goggle (NVG) operations in aviation, this light now features concurrent visible and infrared (IR) outputs as standard, ensuring visibility to both conventional and NVG-equipped aircraft.
Designed to support a wide range of applications and configurations, the AV-OL-LI features a broad DC input voltage range from 12 to 48 volts, making it adaptable to diverse installation environments while optimizing cabling and power efficiency. The light also incorporates user-configurable inputs and outputs to meet FAA monitoring requirements and to interface seamlessly with obstruction lighting controllers. These controllers can optionally include SATCOM or GSM remote monitoring and be managed via the Star2M platform, enabling real-time oversight and diagnostics.
This next-generation obstruction light incorporates internal diagnostics and de-coupled, failsafe alarming for both visible and IR outputs, as well as photocell status. It provides comprehensive alarm and status reporting, critical for ensuring uninterrupted safety in both commercial and defense-related operations. The unit’s operation mode is adjustable and can be configured for automatic dusk-to-dawn functionality or continuous 24-hour operation, depending on the site requirements.
Constructed with high-durability materials, the AV-OL-LI is built using UV-stabilized LEXAN® polycarbonate for both the body and lens. It offers full 360-degree horizontal light distribution and meets ICAO vertical divergence specifications with its advanced single LED optic system. The light source is a long-life LED with an expected lifespan of over 100,000 hours. Despite its robust construction and high-performance capabilities, the unit remains lightweight at just 0.5 kg (1.1 lbs) and compact in size, measuring 160 mm (6.3 in) in height and 121 mm (4.76 in) in width.
Electrically, the AV-OL-LI integrates circuit protection and is built to operate in extreme environmental conditions, with a wide temperature tolerance from -40°C to +55°C. It meets stringent military-grade standards for shock (MIL-STD-202G, Method 213B), vibration (Method 204), and is capable of withstanding wind speeds of up to 240 km/h (150 mph). The light also performs in 0 to 100% humidity environments and is certified for EMC compliance under EN61000-6-4:2019 and EN61000-6-2:2019. Manufactured under ISO9001:2015 quality assurance processes, the AV-OL-LI is designed for a service life of 12 years or more, offering long-term reliability in demanding obstruction marking applications.
With its powerful combination of visible and IR output, advanced monitoring capabilities, rugged construction, and full regulatory compliance, the AV-OL-LI sets a new standard for low-intensity obstruction lighting.
