TFLEX STS MODULE
The most flexible and corrosion-resistant optical unit for your tunnel projects
In tunnels, creating optimal driving conditions is essential, especially where the environment is challenging. A high level of visibility and perfect uniformity are essential to ensure users’ safety inside the tunnel.
TFLEX STS MODULE provides robust lighting modules designed to enhance the road tunnel experience, even in the most difficult situation. Part of the TFLEX stainless steel concept, TFLEX STS MODULE is made of high grade corrosion-resistant stainless steel capable of resisting extreme conditions.
Equipped with optimised optics, it provides perfect visibility and uniformity throughout the tunnel, to guarantee driver safety. Its modular-based concept delivers a tunnel lighting solution capable of adapting to all kinds of tunnel project.
More than an optical unit, TFLEX STS MODULE is a complete solution, offering lighting, smart cabling and control all in one.
- Powerful and reliable
- Enhanced lighting experience
- Easy cabling
TFLEX STS MODULE is made of a high grade corrosion-resistant stainless steel alloy developed to work perfectly in tunnels with extreme conditions. Its different heat sink concepts allow optimal heat dissipation, resulting in better performance over time. Made of 100% durable and recyclable materials, TFLEX STS MODULE offers a robust yet sustainable lighting solution.
Available in two sizes, TFLEX STS MODULE can be used alone, directly or remotely assembled. This modular approach offers the possibility of creating various lighting configurations to fit any tunnel project or geometry.
TFLEX STS MODULE integrates the latest tunnel optic technologies to optimise lighting levels on road and wall surfaces, while providing high visual comfort. TFLEX STS MODULE enables flexible dimming with an optimised power factor, delivering outstanding performance and leading to unparalleled energy savings.
TFLEX STS MODULE uses CPR-compliant custom-length cables with tool-free connectors to drastically ease and reduce mounting time.
TFLEX STS DRIVE is the driver box enabling remote assembly with one or two TFLEX STS MODULEs. This remote connection is ensured by pre-assembled CPR-compliant cables, with tool-free connectors to guarantee fast and easy installation. Integrating the most recent drivers and control technologies, TFLEX STS DRIVE is compatible with the Advanced Tunnel System 4 (ATS 4 and ATS 4 DALI), a powerful tunnel control system enabling precise dimming and switching, installation commissioning, as well as monitoring and reporting. No matter how variable the tunnel conditions might be, this control system enables your TFLEX STS MODULE to provide a quick response to any sudden event.

TFLEX STS MODULE is compatible with the Advanced Tunnel System 4 (ATS 4 and ATS 4 DALI), a smart control solution co-developed by Schréder and Phoenix Contact.
Installation and Maintenance
The fixed brackets allow standard mounting on flat surfaces, be it on walls or ceilings. The brackets are ANSI 3G vibration validated.
The electrical connection to the gear box or other modules is achieved via pre-assembled CPR-compliant cables, equipped with tool-free connectors, drastically reducing installation time and avoiding any wiring issues.
