The HA-OL LED Obstruction Light from Holland Aviation offers a high-performance, low-intensity lighting solution for safely marking fixed obstacles up to 45 meters (150 feet) in height, particularly in nighttime or low-visibility conditions. Engineered for versatility and compliance, the HA-OL is available in both 110–240 VAC and 12/24 VDC power configurations, and is also offered in a double version (HA-OL2) for redundancy and increased reliability. This model features a compact, lightweight design, measuring Ø112 x 200 mm and weighing only 1.5 kg, making it easy to mount and ideal for a broad range of aviation, telecommunications, and infrastructure applications.
Constructed from heavy-duty aluminum with chromate conversion treatment and finished in highly visible yellow RAL 1021 powder coating, the HA-OL is built to withstand harsh environmental conditions. The robust housing ensures corrosion resistance, while the IP65 ingress protection rating allows for reliable performance in temperatures ranging from -40°C to +55°C. The optical system features a borosilicate glass Fresnel lens designed to meet L-810 low-intensity light specifications, providing precise light distribution and long-lasting clarity.
The HA-OL utilizes a 7-watt LED with an operational life exceeding 75,000 hours, offering exceptional energy efficiency and low maintenance. The light output complies with both ICAO Class A (greater than 10 candela) and Class B (greater than 32.5 candela) requirements. An integrated infrared (IR) LED enhances detection through night vision goggles (NVG), ensuring enhanced situational awareness and improved aviation safety in low-light conditions.
Installation of the HA-OL is straightforward, thanks to its 3/4" female threaded base, which allows for direct grid mounting or use with an optional junction box. This ease of installation, combined with the light’s long lifespan and rugged construction, makes it a cost-effective and dependable choice for airspace management and obstacle identification.
The HA-OL LED Obstruction Light is fully compliant with global aviation safety standards, including FAA AC 150/5345-43J, ICAO Annex 14 (Volumes I and II for Aerodromes and Heliports), EASA ADR, and UK CAP 168 and CAP 437. With its blend of performance, compliance, and durability, the HA-OL is a trusted option for marking tall structures such as towers, cranes, chimneys, and buildings to ensure aircraft safety and regulatory adherence.
