FTS 370i Vanguard Integrated Wind Turbine Lighting

L-864 LED Obstruction Lighting System for Wind Turbines

The Vanguard FTS 370i IR is uniquely designed to accommodate the latest developments in wind turbines. In addition to being certified to the new FAA specification (FAA AC 150/534-43J), this lighting system is designed to work with Aircraft Detection Lighting System (ADLS) radars from market leaders like Detect™ and Terma™. Flash Technology’s new FTC 370 Lighting Control Module (LCM) enables wind farms to eliminate light pollution and realize significant energy savings.


The compact FTS 370i is a fully integrated, stand-alone LED obstruction light that does not have a controller taking space inside the nacelle. Incorporating patented optics and industry-leading surge protection, the FTS 370i has proven its reliability through years of field operations. With both FAA L-864 and ICAO Type B certifications, the FTS 370i can be used in standalone or dual configurations (turbine rotor tip height greater than 500 feet) specified by the FAA, ICAO and other regulatory agencies.
