Solar Medium Intensity Type B Dual Aviation Obstruction Light | YFFY-MB-01(L)
YFFY-MB-01(L) Solar Medium Intensity Type B Aviation Obstruction Light is designed to provide reliable aircraft warning for tall structures where grid power is unavailable or difficult to install.
The solar-powered system combines high-efficiency photovoltaic charging, battery storage, LED light sources and automatic light control into one integrated solution. It can operate independently without external AC power, helping simplify installation and reduce long-term maintenance requirements.
The light uses a high-strength aviation-grade aluminum housing and an optimized LED optical system to provide stable light output and 360° horizontal visibility. Built-in surge and overcurrent protection help improve reliability in outdoor environments exposed to rain, wind, UV radiation and lightning.
Typical applications include telecommunication towers, power transmission towers, wind turbines, industrial chimneys, high-rise buildings, bridges and other aviation obstacles.
For multi-light projects, YFFY Lights can also provide customized GPS synchronization, wireless synchronization, remote monitoring and control according to project requirements.
