The versatile, powerful, tunnel lighting solution


Part of the TFLEX tunnel lighting concept developed by Schréder, TFLEX COMBI is the combination of the powerful lighting modules of TFLEX MODULE and the advanced driver box, TFLEX DRIVE. This versatile alliance provides the most flexible, optimised, energy-efficient lighting solution for all standard tunnel zones .
TFLEX COMBI is a complete lighting solution, offering optical and power units, flexible mounting, smart cabling and control technology at once.
Don’t waste time with multiple sourcing and take advantage of a complete lighting solution that suits all typical tunnel zones from entry to exit.

  • All-in-one solution
  • Don’t waste time with multiple suppliers and take advantage of a complete solution. The TFLEX lighting solution offers various configurations and tunnel lighting distributions to meet an entensive range of tunnel projects. A variety of mounting, cabling and controlling options make TFLEX COMBI the most complete tunnel solution, developed to satisfy all types of tunnel requirements.

  • Adapts to all tunnel configurations
  • TFLEX COMBI comes with a large variety of mounting options, orientable and swivelling, enabling mounting on walls and ceilings, in every type of tunnel geometry.

  • Enhance security and well-being in tunnels
  • High uniformity and excellent visibility are critical for tunnels. Taking advantage of the latest photometrical technologies, TFLEX COMBI optical units come with a series of customisable and orientable optics to deliver excellent uniformity throughout the tunnel and enhance drivers security.

  • Plug and play
  • TFLEX COMBI uses pre-assembled cables and connectors to drastically ease and reduce the mounting time. Access for maintenance activities is completely tool-free for maximised time savings.

Latest tunnel technologies

Integrating the latest remote control technologies, TFLEX COMBI is compatible with the Advanced Tunnel System 4, designed to adapt the lighting level according to corresponding conditions in and outside of the tunnel. It monitors power consumption and reports potential failures for maintenance, maximised flexibility, safety and a better driving experience.

A total package for any tunnel project

TFLEX COMBI is an all-in-one solution which combines photometrical, control, mounting and cabling solutions to suit every tunnel geometry. The combination of customisable optical units, mounting options, and the latest tunnel technologies (Advanced Tunnel System 4) makes TFLEX COMBI the most flexible and complete tunnel solution. It benefits from in-depth studies, allowing Schreder to provide the customer with a complete and enhanced tunnel lighting experience.

Control systems

TFLEX COMBI control options

TFLEX COMBI has the following dimming / control options:
• Remote management
• DALI or 1-10V network protocols
• Bi-power

TFLEX COMBI is compatible with the Advanced Tunnel System 4 (ATS 4), a smart control solution co-developed by Schréder and Phoenix Contact. This solution is probably the most powerful on the market. It has been designed to provide auto-commissioning, seemlessly adapt the lighting level according to applicable standards and conditions in the tunnel, to monitor the power consumption and to report any failures.

Installation and Maintenance

Flexible installation

TFLEX COMBI is available with a large variety of mounting options. It offers 6 types of brackets; fixed, adjustable or swivelling, in stainless or galvanised steel. This mounting modularity allows TFLEX COMBI to meet all types of tunnel geometries.

Easy access for maintenance

The access to the driver box is tool-free, using a latch. The electrical connection is made via pre-assembled cables and connectors to drastically reduce the installation time and avoid any wiring issues.

Accessories and versions

Fixed brackets

The fixed brackets allow standard mounting on flat surfaces, whether it is on walls or ceilings.

Suspended and wall pull-out brackets

The pull-out fixation brackets facilitate the installation on walls and ceilings while the fixation consists of eliminating any luminaire weight constraints. The luminaire can be easily inclined to preset values ranging from -20 to +20°.

Suspended and wall adjustable brackets

The adjustable fixation brackets ensure flexible mounting for both walls and ceilings as they are capable of adapting to any tunnel configuration. The adjustable brackets enable slight shifts to the left or to the right in combination with a gradual inclination to deliver the ideal lighting for your tunnel.

Hook fixation

The hook fixation enables mounting on a cable rack. This fixation can be adjusted according to the size of the cable tray (up to 400m), offering great mounting flexibility.
