OBAGA NEGRA TUNNEL, SPAIN

Located in the Pyrenees Mountains in Spain, the Obaga Negra tunnel has been retrofitted to reduce energy usage.  The TLACS solution optimizes the lighting levels of the entrance HID luminaires as well as the new interior LED luminaires.  The solution mixes individual control of the HID luminaires and group dimming control for the interior LED luminaires. The control system selects the required lighting level based on the external and interior lighting conditions. Remote control and monitoring was implemented thanks to the TLACS Network Controller’s embedded web server.
