LED Medium-Intensity Red & White Dual Aviation Obstruction Light
The YFFY-MI-BF Medium-Intensity Aviation Obstruction Light is a Red & White dual-color LED aviation warning light designed for tall structures and aviation obstacles typically requiring medium-intensity marking. The Red and White Medium-intensity Aviation Obstruction Light designed for marking the top of obstacles which height is between 45 – 150 meters.
It provides flashing white light during daytime and flashing red light at night, with automatic day/night switching through an integrated photocell. Self-designed reflector is used to converge light, which could reach the standard light intensity with as less as the power consumption. The high-efficiency CREE LED optical system provides 360° horizontal visibility and stable light output for reliable obstacle identification, ensure the long life experience and good performance.
The light is suitable for communication towers, chimneys, wind turbines, high-rise buildings, tower cranes, bridges, and other structures. GPS synchronization, remote monitoring, and other control functions can be customized for large-scale projects.
As an experienced aviation obstruction light manufacturer, YFFY Lights provides OEM, ODM, and project-specific lighting solutions for different power supplies, flashing modes, synchronization systems, and installation requirements.
