Obaga Negra Tunnel in the Pyrenees in Spain.

Located in the Pyrenees in Spain, the lighting system of the Obaga Negra tunnel has been renovated to reduce energy consumption. The TLACS solution is used to optimize the light levels of the High Pressure Sodium (HPS) luminaires at the entrance as well as the LED luminaires located inside the tunnel. The solution consists of individual control for sodium luminaires and group control for LED luminaires. The control system allows you to select the required lighting level according to the outdoor and indoor lighting conditions. Remote control and monitoring is possible for each system through a web server integrated into the TLACS network controller.
