FAQ
Q1: What Height Range Of Structures Or Obstacles Is This Solar Medium Intensity Obstruction Light Suitable For?
A: According to ICAO and CAAC regulations, the YFFY-MI-A2 Type A Medium Intensity Obstruction Light is primarily used to mark the top of obstacles between 105 meters and 150 meters in height. If a structure exceeds 150 meters, a combination of high-intensity obstruction lights or multi-tier medium-intensity lights is typically required.
Q2: Can This Solar Medium Intensity Obstruction Light Operate Reliably During Continuous Rainy Or Cloudy Weather?
A: Absolutely. YFFY’s solar aviation warning light is equipped with a high-capacity battery and a high-efficiency monocrystalline solar panel. At the factory default flash rate of 20 FPM, a full charge supports more 100 hours (approximately 7–10 days) of continuous operation without sunshine. Extended autonomy options are also available upon request.
Q3: How Does The Device Prevent Internal Short Circuits Caused By Water Condensation When Installed At High Altitudes?
A: The YFFY-MI-A2 solar light features an industrial-grade waterproof breathing valve (vent design) under its die-cast aluminum base. This valve allows gas molecules to pass freely to equalize internal air pressure and temperature while completely blocking liquid water and high-pressure steam, preventing condensation in harsh high-altitude environments and significantly extending electronic component life.
Q4: How Is Synchronized Flashing Achieved When Multiple Obstruction Lights Are Installed On The Same Structure Or Region?
A: The YFFY-MI-A2 Solar Medium Intensity Obstruction Light features a built-in high-precision GPS module. Without laying extra synchronization cables or installing complex central control panels, each light receives satellite timing signals to achieve global, high-precision wireless synchronized flashing automatically.
Q5: Does This Product Support Night Vision Goggles (NVG) Mode Or Remote Alarm Output?
A: Yes, we offer several optional customized features:
-
Infrared LED (NVG Compatible): Enables pilots wearing Night Vision Goggles to identify obstacles easily.
-
Dry Contact Alarm Output: Includes NO/COM/NC interfaces to connect to building BMS or remote monitoring systems for fault alerts.
-
Bird Deterrent Spike: Prevents birds from roosting, ensuring solar panels remain clean for optimal charging and clear lens visibility.
