FTS 370i Vanguard Integrated Wind Turbine Lighting

L-864 LED Obstruction Lighting System for Wind Energy Turbines

The FTS 370i Vanguard® Integrated for Wind Turbine Lighting is an FAA L-864 or ICAO Type B medium intensity aircraft warning light. It is an integrated system; no external system controller is required. Through the use of red LEDs and optional infrared LEDs, the design creates a perfect solution for lighting wind turbines.


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


FTS 370i Wind Turbine Lighting Features

  • Interleaved LEDs and by-pass circuitry provide longer life by allowing the loss of individual LEDs up to the 25% limit
  • Superior surge suppression rating of 200kA protects against 99% of lightning strikes; tested and verified by third-party laboratories
  • Patented, community-friendly Fresnel optics to minimize ground scatter
  • Patented, 360 degree photodiode light collector for a more accurate mode change
  • Aircraft Detection Lighting Systems (ADLS) interface
  • Versatile mounting options
  • Patented 360-degree light collector
  • Rugged GPS receiver for reliable synchronization
  • Improved synchronization capabilities address noise, RF and electrostatic interference
  • An intelligent beacon can be configured for a global wind marking solution
  • A single dry contact conveys LED, sync and mode status
  • 5-year warranty


FTS 370i Wind Turbine Lighting Options

  • Infrared lighting – NVG and NVIS compatibility using 850nm infrared (IR) LEDs
  • An additional overvoltage protection device mounted inside the nacelle protects for lightning protection zone 1 (LPZ 1)
  • Adjustable mounting pedestal for mounting in variable mounting positions
