The wind turbines are positioned along the coastline. In this area, the severe environmental conditions required very high quality lighting fixtures, equipped with a marine grade finishing treatment. Another critical issue consisted in lighting the turbines, more than 100 meters high, given the limited space available for installation and the customer's request to illuminate the entire body including the blades each about 75 meters long. The choice of MPColor 24 RGBW by Studio Due, thanks to the narrow beam and the powerful light output, allowed to obtain the best result.
