From Monday, August the 28th to October the 10th, the summit beacon will remain turned off due to maintenance works.
The beacon, sending out two light beams with a reach of 80 kilometres, is composed of 4 "marine" motorised projectors. They are operated by automatically piloted computer programs. Since their rotation sweep is 90°, they are synchronized to form a double beam in a cross that pivots around 360°. The xenon 6000 watt lamps were chosen for their longevity, around 1,200 hours. The lamps are cooled to prevent overheating and a heating system is activated when the temperatures drop below zero Centigrade whilst the lights are off. This beacon resonates the image of Gustave Eiffel's Tower itself as a universal and symbolic landmark.
