The HP 12-A LED heliport beacon is a high-performance white flashing light specifically engineered to provide long-range visual guidance for pilots approaching a heliport. It is particularly effective in environments where ambient lighting or surrounding structures may obscure visibility or make identification of the heliport difficult. This beacon plays a vital role in ensuring flight safety and is a mandatory component according to the International Civil Aviation Organization (ICAO) Annex 14 recommendations for heliport lighting.
Strategically installed either directly on or adjacent to the heliport, the beacon is ideally mounted in an elevated position to maximize visibility from a distance while being carefully angled to avoid dazzling pilots during final approach or when in close proximity. The HP 12-A is designed with a specialized optic reflector lens that produces a narrow and highly concentrated beam. This optical precision enhances the effectiveness of the flashing light in cutting through fog, rain, or the visual clutter of surrounding city lights.
The HP 12-A operates with high-efficiency LEDs, offering a remarkably long service life of over 100,000 hours. With a flash frequency of 2 flashes per second, it produces light intensities that comply with ICAO Annex 14 photometric standards across multiple beam angles: 250 candela at 10°, 750 candela at 7°, 1700 candela at 4°, and up to 2500 candela at 2.5° and 1.5°, ensuring maximum visibility at both wide and narrow viewing angles. Its energy-efficient 15W power consumption is supported by a universal AC 100–250V power input, with DC 48V and other custom voltages available upon request.
Constructed from durable materials, the body and base are made of corrosion-resistant die-cast aluminum finished with a protective black powder coating. The lens, raised 10 mm above grade after installation, is formed from UV-stabilized polycarbonate offering outstanding impact resistance, optical clarity, and flame retardancy (UL94V-0). The unit’s compact overall dimensions (210 mm diameter by 140 mm height) and a base mounting pattern of 126 mm x 126 mm with M10 bolts allow for straightforward installation.
Weighing approximately 3 kg, the HP 12-A is rated IP65 for protection against dust and water ingress and is built to withstand harsh outdoor environments, including wind speeds of up to 80 m/s and temperature extremes ranging from -40°C to +60°C. An integrated surge protection module (rated for In 7.5 kA/5 times, Imax 15 kA) further reinforces its reliability in lightning-prone or electrically noisy environments.
In addition to its LED-based design, an alternative version of this beacon, known as the HL-12-A, features a high-efficiency cold light xenon tube with a luminous efficacy of 100 lumens per watt and an extraordinary flash lifespan of up to 100 million operations. This model is widely adopted in both domestic and international aviation installations. It uses similar rugged materials such as SUS304 stainless steel and cast aluminum housing with oxidation treatment, ensuring excellent resistance to shock, corrosion, water intrusion, and aging.
Overall, the HP 12-A and HL-12-A heliport beacons are essential lighting solutions for helipads located on high-rise buildings, surface-level or elevated heliports, offshore platforms, construction cranes, and airfields. Their robust design, superior light output, and compliance with global aviation standards make them indispensable tools for enhancing heliport visibility and ensuring safe helicopter operations under challenging visibility conditions.
