100,000 meters of LED strips for the world’s longest immersed tunnel
Customized Tunnel Lighting for the Fehmarnbelt Tunnel
100,000 meters of LED strips for the world’s longest immersed tunnel
How do you ensure stable and safe work lighting in an 18-kilometer-long subsea tunnel under construction?
The answer is robust, customized tunnel lighting—developed for demanding infrastructure projects.
In 2024, we delivered 100,000 meters of LED strips with integrated battery backup for the construction of the Fehmarnbelt Tunnel—the world’s longest immersed tunnel between Rødbyhavn and Puttgarden. The project is scheduled for completion in 2029 and is one of Europe’s largest transport infrastructure projects.
Need
Temporary tunnel lighting with maximum operational reliability.
Tunnel construction places extreme demands on:
- Continuous work lighting
- Safe passage through long tunnel sections
- Robust construction lighting in wet and harsh environments
- Emergency lighting in case of power failure
The project required a total of 100,000 meters of temporary tunnel lighting, with battery backup to ensure illumination even during power outages.
In a tunnel project of this scale, stable LED lighting is not just an advantage—it is essential for HSE, progress, and safe operations.
Solution
Customized work lighting with LED strips and battery backup.
We developed and delivered a complete tunnel lighting system based on:
- 100,000 meters of professional LED strips
- Integrated battery backup for emergency lighting
- Customized lighting solution – tailored to the tunnel’s length and segmentation
- Efficient installation and flexible adaptation throughout the construction phase
Our LED strips are designed for temporary construction lighting, with a focus on:
- High luminous output
- Low energy consumption
- Impact-resistant and robust construction
- Easy installation in tunnels and construction environments
Result
Safe and efficient tunnel lighting.
With our tunnel lighting solution, we contribute to:
- Increased safety for workers in the tunnel
- Stable work lighting throughout the construction period
- Reduced risk during power outages
- Efficient progress in one of Europe’s largest tunnel projects
The delivery to the Fehmarnbelt Tunnel demonstrates our capacity to supply large volumes of LED strips and customized work lighting for complex infrastructure projects.

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 component requirements
- Long service life
the solution contributes to lower and more predictable operating costs.
