FTS 370i-2 Vanguard Integrated Wind Turbine Lighting

L-864 LED Obstruction Lighting System for Wind Energy Turbines

The Vanguard Medium FTS 370i-2 IR is available as an FAA L-864 or ICAO Type B medium intensity aircraft warning light. Since it is an integrated system, no external system controller is required. Utilizing red LEDs and infrared LEDs, the design creates a perfect solution for wind turbine lighting systems.


For wind turbines with a rotor tip height between 500’ and 700’, two Vanguard 370i-2 IR units can be used together on one nacelle to meet FAA AC 70/7460-1L specifications. The Vanguard FTS 370i-2 IR features standard GPS synchronization to ensure proper flashing characteristics.
