Corrosion-proof tunnel lighting for energy efficiency and easy installation


TLI is a range of tunnel luminaires designed for performance, flexibility and ease-of installation. This line provides the ideal solution for extremely corrosive environments and countries where legislation imposes the use of stainless steel housings.
Available in two sizes, TLI is suitable for surface mounting onto ceilings or walls using brackets. This tunnel lighting solution is guaranteed to improve the driving experience and to boosting tunnel safety.
This powerful LED tunnel lighting solution includes robust, corrosion-free luminaires with various lighting distributions, including counter beam photometries, and control systems to provide major operational benefits.

  • For safer tunnels
  • A well-lit tunnel minimises the risk of accidents and critical incidents. TLI increases visibility and enables drivers to detect a potential danger and react in good time to guarantee a safe stopping distance. It helps increase tunnel safety, as it complies with the most stringent standards.

  • Easy to install
  • Designed for high efficiency and a long service life, TLI also makes life easier for installers thanks to its external tool-free QPD connectors that can be combined with Schréder's smart cabling.

  • Designed for corrosive environments
  • This range of tunnel luminaires provides the ideal solution for extremely corrosive environments and countries were legislation imposes the use of stainless steel housings.

  • Optimal performance
  • Designed for long-lasting performance, TLI comes with a wide range of lighting distributions to suit numerous tunnel configurations.
    The TLI LED luminaire is available in two sizes and can be equipped with two types of photometric engines: LensoFlex®2 or ReflexoTM. The aluminium reflectors ensure optimal performance with high visual comfort at the tunnel entrance.

Control options for TLI

TLI comes with the following dimming/control options:
• 1-10V
• Lumgate

The TLI range has been developed to enable constant dimming with an optimised power factor. Designed with two electronic circuits, each TLI luminaire can either be dimmed completely, partially or even have 50% of its LEDs switched off.
