Powerful, modular, corrosion-resistant tunnel lighting solution


In tunnels, creating optimal driving conditions is essential, especially where environments are challenging. Safety, visibility and reliability are a must when dealing with harsh atmospheric conditions. TFLEX STS COMBI is part of the TFLEX stainless steel concept, providing a powerful, strong, corrosion-resistant luminaire.
The result of an alliance of the TFLEX STS MODULE lighting modules and the TFLEX STS DRIVE gear box, TFLEX STS COMBI is the most flexible, optimised, energy-efficient lighting solution for tunnels with harsh environments.
More than a luminaire, TFLEX STS COMBI is a complete tunnel lighting solution, offering both optical and power units in different lengths and configurations, along with smart cabling and remote control technology.
Be ready to face all your tunnel challenges with TFLEX STS COMBI.

  • All-in-one tunnel solution
  • With TFLEX STS COMBI, there is no need to waste time with multiple sources any more. This modular luminaire covers all your tunnel lighting needs, from the light source to the control system, including fast, tool-free cabling. Available in various configurations, with multiple lighting distributions and stainless steel grades, TFLEX STS COMBI is the most complete and robust tunnel lighting solution.

  • Designed to work in extreme conditions
  • Made of high-grade stainless steel alloys, TFLEX STS COMBI provides the perfect solution for environments where the luminaires are exposed to a very corrosive atmosphere. Available with two types of heat sink, TFLEX STS COMBI adapts to the local requirements of each type of tunnel while ensuring optimal heat dissipation. This feature improves the longevity of the installation and maintains the photometric performance of the installation over time.

  • Enhanced safety and well-being in tunnels
  • High uniformity and excellent visibility are critical for tunnels. Taking advantage of the latest photometrical technologies, TFLEX STS COMBI optical units come with a series of flexible optics to deliver excellent uniformity throughout the tunnel and to enhance driver safety.

  • Save valuable time on site
  • TFLEX STS COMBI uses CPR-compliant cables and connectors to drastically ease and reduce mounting time. Access for maintenance activities is completely tool-free for maximised time savings.

Connected lighting solution for safer tunnels

In tunnel environments, nothing should be left to chance. That’s why TFLEX STS COMBI is compatible with the Advanced Tunnel System 4 (ATS 4 and ATS 4 DALI). The ATS 4 is a powerful control system, enabling precise remote dimming and switching of each connected luminaire, based on various tunnel parameter inputs. No matter how variable the tunnel conditions might be, this control system enables TFLEX STS COMBI to provide a quick response to any sudden event. Connected to the ATS 4, TFLEX STS COMBI maximises tunnel safety and enhances the driving experience.

Your lighting partner from A to Z

TFLEX STS COMBI is part of the Schréder tunnel lighting concept. This project philosophy is your guarantee of receiving the best solution for your environment. From the first photometrical study to designing, incorporating the installation, commissioning, testing, validation and training, our lighting engineers analyse your project to design a lighting solution adapted to your requirements and standards.
Providing the most complete, corrosion-resistant, modular-based tunnel lighting platform, the TFLEX STS luminaires are fully part of this philosophy. With TFLEX STS COMBI, tunnels with harsh environmental conditions can finally benefit from a complete lighting package including light source, custom-length cabling, toolless connectors and an advanced control system.
