Obstruction Lights 101 – Use Bird Spikes to Prevent Birds From Landing

Flashing warning lights on turbine nacelles are mostly for the benefit of aircraft flying at night. The lights have progressed from incandescent to LEDbased units. The features of several recent lights show advanced systems.

twr wholeThe L450-864-G from TWR Lighting is one type of obstruction light for wind turbines. 

One model of obstruction light comes in a one-piece mount. An internal enclosure houses the flash circuitry and GPS synchronization circuitry, so it can synch up with other lights of the same model in the vicinity. A bird spike on the dome discourages its use as a resting pad. The light’s beam projects 360° with a 3° divergence at 50% peak vertical. The 33-lb light comes with a regulated power supply with over-voltage protection, and contacts for monitoring and alarms. An internal photocell eliminates need for an external one, and it runs on 100 to 240 Vac.

Another light features a compact flash head to reduce wind load on fixed obstructions such as wind turbines, towers, and bridges. Operating at just 20W, the series of lights is said to offer the lowest power consumption of any L-864 product (FAA designation for a flashing red obstruction light, 20 to 40 flashes per minute) to help save energy and reduce operating costs. With less than an 8.5-in. height, the shock and vibration-resistant lights offer a low profile to reduce the impact of wind shear on the mounting structure, making it well-suited for high-altitude applications and improved performance in inclement weather.
