The SP-102 is a compact, omnidirectional red obstruction light designed to comply with ICAO Annex 14 standards for Type A Low Intensity aviation lighting. Engineered for temporary and portable airfield applications, it is ideally suited for marking hazards, barricades, and obstructions at airports or other aviation environments. Utilizing LED optics, the SP-102 ensures accurate photometric performance in terms of intensity and chromaticity, delivering reliable and consistent illumination over its entire operational lifespan. The optical head is interchangeable, and the LED light engine boasts a minimum lifetime of 100,000 hours, maintaining consistent output throughout.
This self-contained lighting unit operates on a standard deep-cycle, sealed lead-acid battery (SLAB), which is approved for air transport and offers a capacity of 4.5 Ah at 6V. The battery is user-replaceable and features an onboard indicator for status monitoring. It supports multiple recharging methods via the OCT-102 charger or an external solar panel, offering flexible deployment in remote locations. Charging time is approximately 8 hours with the charger and around 12 hours with solar input. A built-in microprocessor provides intelligent control and battery protection, including automatic light control (ALC), which reduces output when battery levels are low to prolong operation.
The SP-102 supports a wide range of operating modes, including steady-on at three brightness levels (min, medium, max), as well as flashing at selectable frequencies (30, 60, or 120 flashes per minute). It also offers an NVG-only mode for covert operations and a combined NVG-visible setting, making it suitable for both visual and night vision goggle operations. The last mode selected is stored in memory for automatic recall upon restart. These features are accessed through a multifunctional push-button interface that manages power, mode selection, reset, and activation lockout.
Ruggedly constructed from non-corrosive aluminum, the SP-102 is built to withstand harsh outdoor conditions. It is IP65-rated for water and dust ingress and resistant to UV exposure. The standard configuration features a glass dome, with an optional UV-resistant polycarbonate dome available for higher durability. Operating temperatures range from -20°C to 50°C in the standard version, with an arctic pack option extending this range from -40°C to 80°C. The compact unit measures 210 mm in height and 125 mm in diameter, weighing only 2 kg.
This portable obstruction light is frequently deployed for temporary applications such as marking construction zones, closed taxiways, or unserviceable runway areas. It is particularly valuable during airfield upgrades or maintenance when permanent lighting systems are deactivated. The light is also used for general hazard marking, aircraft warning applications, and as a portable solution for temporary barricades. Its flexibility and portability make it ideal for use where permanent power infrastructure is not available.
Obstruction lights in general are used to mark fixed obstacles and are critical for aviation safety. These lights are typically red or white and are either steady or flashing, depending on their classification and the height or type of obstruction. ICAO and FAA guidelines categorize obstruction lights into several types: Type A lights are red steady lights with a light output of up to 10 candelas, typically used for low-intensity applications; Type B also emits red steady light but with a higher minimum output of 32 candelas; Type C emits yellow or blue flashing light at a minimum of 40 candelas; and Type D is a high-intensity yellow flashing light with an output of at least 200 candelas.
At airports, red Type A obstruction lights like the SP-102 are used to mark towers, antennas, construction zones, and areas not in service. These lights can be fixed or portable depending on the application. Permanent installations are typically powered by a 6.6A electrical grid, whereas portable lights like the SP-102 rely on batteries or solar power. Their use during airfield construction is crucial for marking closed or hazardous areas, helping to protect both aircraft and ground vehicles by providing clear visual warnings.
The SP-102 represents a reliable and versatile lighting solution for any scenario requiring temporary or remote obstruction marking in compliance with international aviation safety standards.
