Lighting the world's longest under-sea tunnel

The construction of Ryfast - Norways largest tunnel building project - is underway, and when completed will provide safe passage for those travelling from Jaeren to Ryfylke. Developers sought to make sure the lighting would allow drivers to pass through in complete safety and comfort. 


Customer challenge
 
Many existing tunnels in Norway have been installed with outdated lighting, making the roads dangerous and maintenance an expensive task. Ryfast is designed to support 8,000 vehicles per day, so needed a suitable and effective lighting solution.  


The right lighting 

We installed Philips TubePoint luminaires along the length of the tunnel ceiling, illuminating the entire road in high-quality, bright LED light. Each one also contains a 'flying-lead' cable, allowing quick and easy replacement.

Lux meters have been installed at the tunnel's entrance, inner zone and exit, so light levels can be continuously monitored and adjusted depending on the natural level of light. There's also a radar system that indicates whether a driver has stopped and triggers an evacuation light accordingly. 

Above all, our light system ensures safety at all times. In the event of an emergency or power cut, some of the luninaires will remain on, and highly efficient optics provide a superior spread of light.
