FTS 350i Wind Turbine Lighting System

FAA L-864 Wind Farm Lighting

The FTS 350i is an economical FAA L-864 / ICAO Type B red LED lighting system specifically designed for wind turbine applications that do not require the advanced features of the FTS 370i.


Small and light, this stand-alone obstruction light does not have a controller taking up scarce space inside the nacelle. The weather-proof, UV-resistant, polycarbonate construction provides a 90% weight reduction over the FTS 370i.


The FTS 350i is fully compliant with FAA AC 70/7460-1L requirements for turbines with rotor tip heights less than 699 feet and is certified to AC 150/5345-43J with infrared LEDs.


Standard Features

  • Fully integrated system – no external controller
  • Easy to carry and install on turbines due to extremely low weight
  • Infrared (IR) LEDs for compatibility with NVG and NVIS per FAA AC 150/5345-43J
  • Fresnel optics minimize ground scatter, making the light more community-friendly
  • 10kA surge protection, two times the FAA-specified minimum
  • GPS for synchronized flashing
  • Handheld remote controller simplifies light setup
  • Field-configurable flash rate of 20 or 30 fpm
  • Dry contact alarm for beacon, GPS sync and mode change
  • 2-year replacement warranty


Optional Features

  • Adaptor plates for existing mounting brackets
  • Mounting brackets available for multiple turbine manufacturers
  • Overvoltage protection device (OVP)
