Wind turbines require two different types of lighting: a low-intensity steady burning red light during the construction phase, and permanent medium-intensity flashing red lights after the construction is complete. We offer a complete obstruction lighting package for wind turbines during and after construction.
Temporary marking of wind turbines during construction
To comply with current 2016 FAA recommendations for wind turbine construction, a company must:
- Light wind turbines once they reach 200 feet during construction (submitting a Notice to Airmen [NOTAM] to justify not lighting the turbines is prohibited)
- Use an FAA-compliant L-810 light with a minimum intensity of 32.5 candela (cd)
- Ensure temporary solar lighting systems have 7 days of autonomy at 32.5 cd
Wind turbines under 500 feet (152 meters) must be lit with one L-864 medium-intensity flashing red light. For wind turbines taller than 500 feet, two L-864 lights must be mounted on the opposite rear sides of the nacelle to meet FAA AC 70/7460-1L specifications.
If you have any questions regarding your project, please contact us and we’ll help you determine what lights are required for your wind turbine.
