In the Oscense Pyrenees we find the Cave of the Güixas, an almost dreamlike environment in which we find different calcareous structures shaped by the years and the humidity. To illuminate this natural treasure, the TR4 luminaires in Opal LED version from Airfal were used.
These luminaires have an IP67 rating, which allows them to withstand the humidity in the area without adversely affecting their operation. In addition, the choice of an LED luminaire in this case means both economic and energy savings in a place where the luminaire will be switched on even during the day.
