The tunnel luminaire is engineered to deliver light that lasts, offering long-term performance even in the most demanding environments. Built to meet the highest corrosion classification (C5), it is specifically designed for tunnel applications where durability and reliability are paramount. Its slim, compact, and lightweight form not only contributes to easy handling but also features a no-debris retention design, ensuring that maintenance is minimized and the luminaire remains efficient throughout its service life.
A wide range of optics is available to provide uniform and comfortable lighting, enhancing visibility and safety for tunnel users. This versatility allows the luminaire to be configured for a variety of tunnel zones and requirements, from entry and transition areas to interior and exit sections. With multiple luminaire sizes, remote gear boxes, and adaptable fixation brackets, it offers a flexible solution suitable for different tunnel geometries and installation conditions.
The luminaire housing is constructed with robust materials to withstand harsh tunnel environments. Smaller sizes feature die-cast aluminium bodies, while medium to extra-large versions use extruded aluminium profiles with die-cast end caps for strength and stability. The enclosure consists of 4 mm thick toughened glass, supported by stainless steel components with protective treatments to ensure resistance against mechanical stress and corrosion. A white powder-coated finish in RAL9016 provides a clean, high-quality appearance while reinforcing its durability. Additional components, including brackets, screws, and gear boxes, are manufactured with materials such as stainless steel, reinforced polyester, or coated aluminium to guarantee long-term resilience under constant exposure to moisture, exhaust fumes, and temperature fluctuations.
Installation and maintenance are streamlined thanks to a design that incorporates intuitive mounting options. The luminaire can be fixed to either the ceiling or the wall using dedicated brackets, ensuring flexibility for different tunnel layouts. The remote gear box is supplied pre-wired with a 1.5-meter cable and includes a mounting bracket for straightforward connection and serviceability. This approach reduces downtime and simplifies replacement or servicing during the luminaire’s operational life.
Specifying this tunnel luminaire means choosing a solution that balances power, efficiency, and compactness. Available in five different sizes, it is robust yet lightweight, easy to install, and capable of replacing conventional 600W sodium lamps in demanding tunnel entry zones. Advanced lighting technologies such as Constant Lumen Output (CLO), Adaptive Lighting Output (ALO), and LumGate enable precise adjustment to varying tunnel conditions, ensuring compliance with safety requirements while optimizing energy consumption. With its durable construction, versatile optical options, and efficient design, the luminaire represents a powerful and sustainable choice for modern tunnel lighting.
