ICAO Type B Low-Intensity Dual Solar Aviation Obstruction Light YFFY-LB-01(L)
Solar-Powered Dual Solar Aviation Obstruction Light for Towers, Buildings and Other Aviation Obstacles
The YFFY-LB-01(L) dual solar aviation obstruction light is designed for structures that require reliable nighttime aviation marking.
Its high-efficiency LED optical system provides consistent aviation red light with 360° horizontal coverage and an effective intensity of 32.5 cd. The dual-light configuration provides an additional level of operational reliability: if the primary light fails, the standby light switches on automatically.
The lighting system is powered by a 10 W solar panel and 12.8 V / 14 Ah battery, eliminating the need for a conventional AC power connection. An integrated battery management system helps protect the battery and extend its service life.
The housing is manufactured from aviation-grade aluminum alloy and incorporates an optical PC lens. With IP65 protection, 3 kA surge protection and a -40°C to +55°C operating temperature range, the light is suitable for exposed outdoor installations and demanding environmental conditions.
Dual-Light Reliability
The YFFY-LB-01(L) uses a primary + standby light configuration. When the primary light is detected as faulty, the system automatically switches to the standby light to maintain obstruction marking.
Solar-Powered Operation
The integrated solar power system combines a 10 W solar panel with a 12.8 V / 14 Ah battery, providing an independent power source for locations where grid power is unavailable or difficult to install.
Rugged Outdoor Construction
The aviation aluminum housing, optical PC lens and IP65-rated construction provide protection against rain, dust and other outdoor environmental conditions. The system is also designed to withstand high wind loads and solar radiation.
Key Features
- Dual Light with Automatic Standby Switching: Primary and standby LED light sources provide an additional layer of operational reliability. The standby light activates automatically if the primary light fails.
- Solar-Powered and Grid-Independent: A 10 W solar panel and 12.8 V / 14 Ah battery provide an independent power solution for remote towers and structures without convenient access to grid power.
- ICAO Type B Low-Intensity Light: Designed for low-intensity aviation obstruction marking applications with an effective nighttime intensity of 32.5 cd.
- 360° Horizontal Visibility: The optical system provides full 360° horizontal coverage for consistent visibility around the protected structure.
- Long-Life LED Technology: High-efficiency SMT LED technology delivers low power consumption and a rated light-source lifetime of ≥200,000 hours.
- Built for Harsh Outdoor Environments: Aviation-grade aluminum housing, IP65 protection, 3 kA surge protection and a -40°C to +55°C operating temperature range support reliable outdoor operation.

Frequently Asked Questions of YFFY-LB-01(L) Dual Solar Aviation Obstruction Light
1. What is the YFFY-LB-01(L) aviation obstruction light used for?
The YFFY-LB-01(L) is a low-intensity Type B solar aviation obstruction light designed to mark fixed structures that may present a hazard to aircraft at night. Typical applications include communication towers, buildings, chimneys, bridges, high poles, transmission towers and other elevated structures.
2. What is the difference between Type A and Type B low-intensity obstruction lights?
Both Type A and Type B are low-intensity lights for marking fixed obstacles. The main difference is the required light intensity. Type B provides approximately 32 cd of red steady light at night, while Type A is typically specified at approximately 10 cd. The appropriate light type should be selected according to the applicable aviation regulations and project requirements.
3. Why does the YFFY-LB-01(L) use a dual-light configuration?
The dual-light design provides additional operational redundancy. If the primary LED light fails, the standby light can automatically take over, helping maintain the required aviation warning signal and reducing the risk of an unmarked obstacle.
