Kofl Tunnel


The Kofl Tunnel, almost a kilometer long, is part of project to contain the dangers of the road section of the municipality of San Pancrazio in the provincial road SP 9, the only road axis Val d’Ultimo.

Safety has always been the main focus of the project and lighting should should have been up to it.

Arianna, Kofl Tunnel

Bouygues E&S InTec Italia, which won the redevelopment tender, has chosen Arianna as lighting partner. Thanks to the modularity of Phileo tunnel, the projector chosen for the Kofl Gallery, we were able to illuminate the entire gallery.

1 product, 2 versions, different configurations 0 waste.

When safety is paramount Arianna’s patented total reflection optics are the plus that makes the difference. The lighting of the entrance section, during the day, requires very high levels of luminance, so it is essential to contain the glare. Arianna, thanks to the patent and the choice of hiding the light source, ensures levels of glare well below the required limit (around 2%).

Also in the Permanent area, along the entire length of the tunnel, the Phileo, with low power consumptions, has guaranteed an exceptional uniformity that allows perfect visibility for those traveling along the road in the tunnel.


An exceptional gallery that combines cutting-edge technology and high design. Arianna has succeeded with her lighting to guarantee total uniformity without shaded areas with an energy saving superior to all competitors.

The beauty of the gallery’s architecture has been valued by the careful studies of the Arianna team designers. This results are what make us proud of the meticulousness put into every single calculation. It is these works that incentive us to improve ourselves. Because the gallery is a challenge for many and Arianna excels just where others stop.
