The best of both worlds

Tunnel & Underpass lighting


TRIPLE-C The perfect balance With LED technology in road tunnel lighting we can offer a new balance between Costs, Comfort and Care. The T-line road tunnel lighting luminaire integrates the quality and safety achievable with fluorescent linear lighting with the efficiency and Total Cost of Ownership of high pressure sodium point source lighting. Therefore, T-line perfectly suits Indal’s TRIPLE-C philosophy; providing the perfect balance between Costs, Comfort and Care.

High-quality cool white LED delivered by a linear lighting solution:

LED technology is an energy-saving solution with a positive contribution to the environment:

• Extremely long-life LED light source resulting in less maintenance and high availability. • Efficient lighting system reduces energy costs. • Light weight plug-and-play luminaires reduce installation costs. • Proven, robust mounting technique provides extended construction life.

• Linear lighting solution providing excellent visual guidance and near perfect light uniformity. • Cool white colour solution for improved visibility and a CRI index of 75. • Optimised lighting conditions can improve traffic flow and safety.

• Reduced energy consumption and CO2 emissions. • No over-lighting due to unique dimming features. • Lower lighting levels are sometimes possible due to application of cool white LED linear light. • Luminaire manufactured largely from recyclable materials.

T-line Combining the benefits of fluorescent linear lighting with the advantages of point source lighting Indal has developed a series of linear LED luminaires primarily for road tunnel lighting applications. The result is T-line: road tunnel lighting combining the ‘Comfort’, quality and safety of a fluorescent linear scheme with a Total ‘Cost’ of Ownership of a high pressure sodium point source scheme, with the added benefit of taking greater ‘Care’ of the environment due to LED technology.

Driver installation Each T-line is supplied with a single highly efficient driver. These drivers operate remotely and can be mounted up to 15m away from the luminaire as standard (longer distances can be accommodated with larger cable sizes). As part of the M&E system design, the installation contractor will normally determine the driver installation method and location. However, Indal can provide a number of standard solutions if preferred. The T-line driver can also be integrated into Indal’s i-TunneLŽ Control & Monitoring system, to provide total automatic control of the lighting system.

Advanced REVOLED technology ™

T-line is based on REVOLED™ technology developed by Indal. Thanks to REVOLED™, T-line offers all the benefits of LED light sources. Powerful, high-quality LED’s, the COO-LED™ cooling system and DIRECTA™ lenses give you excellent light quality, high energy savings and low CO2 emissions.

REVOLED™ High-quality power LED’s REVOLED™ uses powerful, high-quality LED’s that contain no mercury and emit no UV radiation. They provide efficient, uniform and comfortable cool white light with superb colour rendering. This improves visibility of vehicles and objects in tunnels and as a result, the safety of drivers and passengers. REVOLED™ also offers energy savings and a big reduction in CO2 emissions.


COO-LED™ For increased LED life span COO-LED™ delivers superior temperature control by combining low current LED’s with a large cooling surface that’s an integral part of the luminaire housing. LED’s are bonded directly to the outer skin of the luminaire eliminating any insulation in the heat dissipation path, which not only ensures high LED efficiency, but also provides an extremely long system life span.

DIRECTA™ Lenses for high optical efficiency and accuracy Patented DIRECTA™ clear lenses are integrated into the luminaire housing with no additional cover required. The result is high luminaire efficiency of 85 to 95%. That’s 10 to 25% more efficient than conventional lighting solutions. DIRECTA™ also allows you to direct the very small LED light source with extreme accuracy, ensuring the best and most efficient lighting solution. What’s more, the lenses are watertight and dustproof (IP 66+) offering extra protection.

saving extra energy consumption.


Compensation of depreciation Like any light source, LED’s are subject to lumen depreciation over their lifetime. But with LED’s this is very predictable. In combination with T-line’s continuous dimming feature, the system can be designed to compensate for LED depreciation. So even as the light output of the luminaires weakens over time, depreciation compensation ensures a constant level of cool white light and prevents significant over-lighting.

Lower lighting levels T-line offers extremely high uniformity levels across tunnel surfaces, including the walls. It also provides excellent visual guidance and better visibility with a high CRI of 75. There is potential to reduce the required lighting levels in certain tunnel projects in relation to the superior quality of light when compared to some traditional light sources.

Lighting on demand Some tunnels are located in areas with low traffic density, where few vehicles pass through the structure during certain parts of the day. Because T-line offers an instant dimming facility, certain tunnels may be suitable to benefit from traffic based control mechanisms. During low traffic use, the lighting could be dimmed to a certain percentage of the required lighting level providing an on-demand energy efficient system.

T-line guarantees high lifetime expectancy T-line offers some of the best lifetime expectancy figures available from a high output LED luminaire, made possible by the variety of unique design features, not least the COO-LED™ technology. T-line is built to exacting standards and uses some of the highest quality power LED’s currently available. In addition, the application of the unique REVOLED™ technology means the longevity of the luminaire is assured. The luminaire design guarantees a very low LED junction temperature, which is the main contributor to early mortality or light depreciation.
