The SP-102 Portable Runway Threshold End Light is a high-performance, ICAO-compliant airfield lighting solution designed for remote, temporary, and infrastructure-limited environments. Engineered with advanced LED optics, the SP-102 ensures precise chromaticity and photometric intensity in accordance with ICAO Annex 14, Volume I, and FAA 150/5345-50B standards. The light’s bidirectional design emits green light toward approaching aircraft and red light in the opposite direction, clearly marking the start and end of the runway. This functionality is critical for safe aircraft operations, particularly at general aviation airports, local aerodromes, grass airstrips, or any site where permanent lighting systems are unavailable or impractical.
Built for versatility and durability, the SP-102 is housed in a non-corrosive aluminum chassis with an IP-65 waterproof rating, making it highly resistant to harsh environmental conditions. The light dome is available in either standard glass or an optional UV-resistant polycarbonate. Thanks to its user-replaceable optics and battery, operators can maintain and service the unit on-site without special tools. Its sealed lead-acid battery is both air-transport approved and designed for long operational life, supporting up to 1,200 charge cycles and a lifespan of 4–5 years. Charging options are flexible, including a standard OCT-102 charger, a solar panel, or an external power source. Charging times are approximately 8 hours via charger or 12 hours using solar energy.
The SP-102 offers multiple operating modes to suit varying operational needs. Lighting modes include steady-on with adjustable intensity (minimum, medium, and maximum), flashing at selectable rates (30, 60, or 120 flashes per minute), and automatic dusk-to-dawn operation. For specialized missions, the light supports night vision goggle (NVG) modes—including NVG-only and NVG combined with visible light—making it suitable for covert or tactical operations. Once a mode is selected via the multifunctional push-button, it is stored in memory, ensuring consistent performance between uses.
Battery management is optimized by a built-in Automatic Light Control (ALC) system that dynamically adjusts intensity to preserve battery life when capacity runs low. An onboard microprocessor manages light functions and safeguards against overcharging or deep discharging. The external battery indicator allows users to monitor charge levels at a glance. For operations in extreme temperatures, the standard unit functions reliably from -20°C to +50°C, while an optional Arctic Pack extends the range from -40°C to +80°C.
The SP-102’s optical system features a long-lasting LED with a minimum rated lifespan of 100,000 hours. The bidirectional red/green light is engineered for consistent photometric output throughout its operational life. Dimensions are compact—measuring 210 mm in height and 125 mm in diameter—while its weight of just 2 kg allows for easy transport and rapid deployment, particularly valuable in emergency or tactical situations.
Runway threshold lights are among the most critical visual aids for safe landing and takeoff, especially in low-visibility conditions or at unlit airports. The SP-102 enhances pilot situational awareness by distinctly marking runway thresholds and ends, even in visually cluttered environments. These lights meet the full scope of international and regional standards, including EN 61000-4 and PN-EN compliance for electromagnetic compatibility, ensuring suitability for deployment across global airfields.
In summary, the SP-102 Portable Runway Threshold End Light delivers a rugged, self-contained, and highly adaptable lighting solution that empowers airfield operators to maintain safe flight operations wherever infrastructure is limited or temporary lighting is required. Its combination of solar charging, NVG compatibility, automatic control, and environmental resistance makes it a preferred choice for aviation professionals operating in both civil and military contexts.
