KLF 2.0 LED linear lights in the tunnel
A two-kilometre-long tunnel deep underground, challenging working conditions and high safety standards: In Schluchseewerk AG’s longest tunnel, 300 permanently installed ELSPRO KLF 2.0 LED linear lights now provide reliable and long-lasting illumination.
The tunnel, which is around two kilometres long and is situated in the southern Black Forest, must be safe to walk through for regular maintenance work. Until now, lighting has been provided on a temporary basis by members of the construction power team.
Last year, Schluchseewerk AG therefore decided on a permanent solution. The access road was equipped with ELSPRO KLF 2.0 LED linear lights. This ensures that reliable lighting is available at all times, without the need to set up a temporary lighting system before the actual work begins.
Greater Safety, Less Preparation Time
Good lighting is an essential factor for safe work, especially in a tunnel. The new lighting solution not only improves visibility but also streamlines work processes: Employees can now safely enter the tunnel and work there at any time without the need for prior preparation. As a result, the permanently installed lighting makes an important contribution to workplace safety while simultaneously reducing the organizational effort required for maintenance and repair work.

Partnership Even Underground
During an on-site visit, the ELSPRO team—consisting of Joachim Bläsi, Chris Ribjitzki, and Hans-Werner Ribjitzki—was able to see for themselves the installation and the unique conditions underground. Robert Schäuble, Subdivision Manager for Maintenance at Schluchseewerk AG, together with members of his team, presented the new lighting system in the tunnel and provided fascinating insights into the working environment deep inside the mountain.
Schluchseewerk AG and ELSPRO have been working together as partners for more than 25 years—on both mobile and stationary solutions in the fields of lighting and electrical engineering.
The lighting of the tunnel using ELSPRO KLF 2.0 LED linear lights is a project that demonstrates: Good light makes all the difference, especially when there is no natural light.
