    The right lighting


    In the tunnel 115 FlowLine LED tunnel luminaires are installed, connected to the networked control system TunneLogic. In addition, we were also responsible for programming, commissioning and testing.

    The linear LED lighting is mounted at the center of the tunnel roof and provide a continuous line of light. Two photometers are installed approx. 40 meters outside of the tunnel entrances, detecting daylight levels and adjusting the lighting in the tunnel entrances according to the outside conditions.

    On the Kvarnholmen bride - which has two-way lanes for car and bus traffic, with a pedestrian pathway and cycle lane running alongside - MileWide2 LED luminaires have been installed on curved cone-shaped poles.

    Both the Kvarnholmen tunnel and Kvarnholmen bridge now have sustainable energy-efficient lighting with long operating times and extremely low maintenance costs. The energy savings are 82%.
