Tunnelsystems™ – robust lighting for demanding conditions
A complete, Norwegian-produced lighting system developed for temporary use during drilling, operation, and rehabilitation of road tunnels, hydropower tunnels, mines, and culverts.

The system is designed with a focus on low weight, high ingress protection, and smart "Plug & Play" solutions – making it easy to install and extremely reliable, even under harsh conditions.

Luminaires or LED strips can be connected every 10 or 20 meters, and the system is phase-balanced to enable long distances without compromising stability.

Tunnelsystems™ significantly simplifies the installation of access lighting and is particularly well suited for tunnel and culvert environments. As an additional feature, the system is also compatible with Exentric WIFI™ – our proprietary network system for smart monitoring and control.

Corporate Social Responsibility
Exentric has its production facilities located in Porsgrunn municipality in Telemark, Norway.

As part of our corporate social responsibility, we collaborate with GREP Grenland AS and utilize VTA (Varig Tilrettelagt Arbeid – Permanent Adapted Work) in the production of Tunnelsystems™.

Tasks such as cable cutting and stripping, assembly of specially adapted components, as well as packing and labeling prior to shipment, are customized and carried out with high precision. These tasks add not only value to the product – they also add meaning and opportunities for people.

The collaboration with GREP Grenland gives Tunnelsystems™ a deeper value. It is not only about technology, but also about inclusion, respect, and sustainable choices.

We are genuinely proud of this partnership.
