TFLEX STS GEN2 BASE

Fully integrated luminaire for tunnels with highly corrosive environments

Description

Tunnels

Tunnels & underpasses

Designed for tunnel interior zones, TFLEX STS GEN2 BASE provides the uniform, constant and reliable illumination required to support safe and comfortable driving conditions. Its corrosion-resistant construction and energy-efficient performance make it a robust solution for demanding tunnel environments and complex geometries.
Integrated within the TFLEX STS GEN2 ecosystem, it offers a complete project approach, from lighting to cabling and built-in control, tailored to the specific needs of your tunnel.
  • Tunnel lighting expertise from design to long-term operation

    • TFLEX STS GEN2 BASE is part of Schréder’s integrated tunnel lighting solutions, supported by expert services from project design to long-term operation. You benefit from comprehensive expertise, ensuring accurate project execution, technical guidance and sustained performance over your tunnel’s lifetime.

  • Long-lasting reliability in harsh tunnel environments

    • Designed for aggressive tunnel environments, TFLEX STS GEN2 BASE combines a corrosion-resistant stainless-steel housing with high-performance thermal management. With two heat sink concepts, it supports long-term reliability, consistent photometric performance and reduced operational risk across different tunnel profiles.

  • Safe, comfortable tunnel driving conditions

    • Combining high-power LEDs with advanced tunnel photometric technologies, TFLEX STS GEN2 BASE delivers precise, efficient illumination where it matters most. Its dedicated optics optimise lighting levels on both road and wall surfaces, enhancing visibility, uniformity and visual comfort for a safer driving experience.

  • Tool-free cabling designed for faster installation

    • TFLEX STS GEN2 BASE is delivered with CPR-compliant, custom-length cables, equipped with tool-free connectors. This concept helps to simplify mounting, reduce wiring issues and support reliable installation on site.

Control-native architecture for responsive, safer tunnel lighting

TFLEX STS GEN2 BASE goes beyond conventional connected-ready luminaires. It is designed as a fully integrated, control-native tunnel luminaire. This design provides compatibility with smart tunnel management platforms such as the Advanced Tunnel System 4 (ATS 4). This control system enables real-time dimming and selective luminaire switching based on luminance, traffic and sensor inputs.
By adapting lighting levels to real tunnel conditions, this intelligent control approach helps to reduce unnecessary energy consumption, maintain the right level of visibility and strengthen the tunnel’s security.

Installation and Maintenance

Adjustable brackets

The adjustable brackets allow flexible mounting on flat surfaces, whether on walls or ceilings. They enable precise luminaire orientation to achieve the required photometry across various tunnel geometries.
Easy access for maintenance

Access to the gear components is tool-free. The electrical connection is achieved via fire-retardant, CPR-compliant cables, equipped with tool-free connectors. This feature drastically reduces installation time, improves quality and avoids any wiring issues.
