Holland Aviation’s HA-OL Medium Intensity obstruction lighting system is a technologically advanced solution engineered to enhance aviation safety by significantly improving the visibility of tall structures. Designed to mark obstacles ranging from 45 meters (150 feet) to 150 meters (495 feet) in height, this medium-intensity beacon ensures aircraft are effectively warned of potential hazards across both day and night operations. Lightweight and robust, the HA-OL system integrates a dedicated controller box capable of managing multiple lights simultaneously, offering a streamlined and efficient lighting infrastructure for large-scale installations.
Purpose-built for aviation environments, the HA-OL series delivers powerful visual alerts through either steady or flashing red and white light configurations that can be seen for miles. It is ideal for high structures such as towers, cranes, buildings, and wind turbines. To ensure uninterrupted visibility and regulatory compliance, the system incorporates a built-in GPS module for time-based synchronized flashing and a twilight sensor that automatically adjusts light output based on ambient lighting conditions. This all-in-one unit provides round-the-clock operational adaptability, reducing the need for manual intervention while enhancing energy efficiency and lifespan.
The HA-OL medium intensity beacon is available in three primary configurations to meet a range of operational scenarios. Type A emits a white flashing light at 20,000 candelas during the day and reduces intensity to 2,000 candelas at night, maintaining a 20–60 flashes per minute (FPM) rate to ensure optimal visibility in both daylight and low-light conditions. Type B is tailored for nighttime use, offering a red flashing signal at 2,000 candelas to enhance safety in darkness. For locations where continuous indication is necessary, Type C provides a steady-burning red light at 2,000 candelas, offering a constant visual warning during nighttime hours. Additional hybrid types (AB and AC) are also available, combining features to further adapt to specific operational requirements.
Designed with durability and reliability in mind, the HA-OL fixture features a rugged housing with ingress protection rated at IP67, ensuring resistance to dust and water ingress even in harsh weather conditions. It has a compact form factor (240 mm diameter x 375 mm height), weighs just 4.5 kg, and is built with a clear lens to deliver maximum optical efficiency. Light color options include red and white, with power consumption levels optimized at 120W for white light and 40W for red or infrared variants. Its certified compliance with ICAO Annex 14 Vol I for Aerodromes, ICAO Annex 14 Vol II for Heliports, EASA ADR, and UK CAP 168 underscores its readiness for global aviation applications.
The HA-OL medium intensity obstruction light series exemplifies Holland Aviation’s commitment to precision engineering and safety. By offering modular, GPS-synchronized lighting with automatic ambient light response, this system stands as a premium solution for marking aviation obstacles while supporting international airspace safety and efficiency.
