The WLS-T25 is a solar-powered, twin low-intensity aircraft warning light specifically engineered for deployment in remote or off-grid locations where electricity is unavailable. Designed with full autonomy, this system offers automatic operation and can function continuously for up to seven days without any sunlight, making it an ideal choice for ensuring safety and compliance in challenging environments.
Built to the stringent requirements of ICAO Annex 14 and FAA L-810 standards, the WLS-T25 features a modular design that integrates a durable aviation light, a duty-and-standby control system, a high-efficiency silicon solar panel, and a rechargeable NiMH battery. The duty-and-standby function ensures continuous operation: if the primary light fails, the system automatically switches to the standby unit, maintaining uninterrupted warning light output. The onboard controller—driven by an advanced microcontroller unit (MCU)—monitors system performance, detects faults, and protects both the light and solar charging system, significantly enhancing reliability and operational safety.
Constructed for rugged performance, the WLS-T25 light housing is made of die-cast aluminum (LM6) with a corrosion-resistant powder-coated finish. This robust design offers lightweight portability, excellent impact resistance, and full waterproofing to IP65 standards. The polycarbonate lamp housing adds an extra layer of durability, offering high transmittance, thermal stability, and superior anti-impact strength. The light’s combustibility rating is UL94V-0, ensuring fire safety compliance in high-risk industrial or environmental zones.
This solar warning light incorporates a high-conversion silicon solar panel with excellent reliability and minimal long-term degradation, contributing to its long operational life. The mounting bracket, fabricated from stamped parts, is engineered to resist harsh environmental conditions and withstand wind speeds up to 100 km/h. It also provides an adjustable inclination angle between 15° and 60°, allowing for optimal solar energy capture based on geographic location.
Operational features include a built-in photocell for dusk-to-dawn operation, an integrated change-over relay, and real-time fault monitoring. Light output is available as steady-burning or flashing (to be specified at the time of order), with selectable intensities between 10 and 32.5 candela in aviation red. The fixture offers a full 360° horizontal light distribution and a vertical beam spread of 10°, ensuring high visibility and effective warning range with a visible distance exceeding 3.6 km at 0.85 atmospheric transmissivity.
With its low maintenance requirements, high reliability, and compliance with international aviation safety standards, the WLS-T25 is ideally suited for remote installations such as telecommunication towers, off-grid industrial sites, oil and gas infrastructure, and other critical obstruction-marking applications. Its ability to function independently and reliably in adverse conditions delivers significant cost savings over time while maintaining the highest safety standards.
