Tunnel Lighting for Infrastructure Projects
Kühtai Power Plant Station, Austria
In the idyllic winter sports village of Kühtai, located in the Stubai Alps in western Austria, you will find the Kühtai power plant station – a project where reliability, energy efficiency, and functionality are at the core.
The lighting system was to be installed in a tunnel and serve both as permanent lighting and emergency lighting. The solution therefore needed to combine long-term stable performance with optimal energy consumption and a high level of safety.
The project reflects many of the same requirements seen in tunnel and infrastructure projects across Norway and the Nordic region:
- Permanent, compliant lighting
- Integrated emergency lighting
- Low energy consumption
- Long lifetime with minimal maintenance
- A robust solution for demanding environments
This makes the project highly relevant for contractors, consultants, and developers working within transport and infrastructure.
Energy-Efficient Tunnel Lighting with Integrated Emergency Function
The lighting system was designed for tunnel installation, serving both as standard operational lighting and emergency lighting.
Solution
The solution was a 50-meter version of M-Flex, optimized specifically for the project’s requirements.
By adjusting and reducing the light output, we achieved:
- Reduced energy consumption
- Lower operating costs
- Maintained required lux levels
- Uniform and safe light distribution throughout the tunnel
For emergency lighting, one emergency module is installed per 150 meters. This provides an efficient and cost-optimized backup solution with fewer components and reduced system complexity.
The result is a complete, integrated system for energy-efficient tunnel lighting with built-in emergency functionality—combining normal and emergency lighting without the need for separate installations.

Scalable solution for Nordic tunnels and infrastructure projects
Tunnel lighting in the Nordic region places additional demands on:
- Temperature variations
- Moisture and harsh environments
- Long-term operational reliability
- Easy service and maintenance
- Documented lighting calculations
The linear system design enables fast installation, fewer connection points, and high system stability—crucial in large infrastructure projects where both progress and total cost are critical.
The solution is scalable and can be adapted to:
- Service tunnels
- Escape routes
- Power plants and energy facilities
- Underpasses and technical installations
- Temporary and permanent infrastructure projects

Optimized economics
In infrastructure projects, lighting is not just about initial investment cost—but a total cost of ownership.
By combining:
- Energy-efficient operation
- Integrated emergency lighting
- Reduced number of components
- Long product lifetime
the solution contributes to lower and more predictable operating costs.
