Accessing tunnel lighting for maintenance can be slow and costly. TRT Lighting’s new R-Range luminaire reduces this burden with tool-free panels and plug-in optical units that cut time spent at height.
It also meets S12 fire safety requirements for sub-surface transport environments, limiting smoke and flame spread. These features make the R-Range a practical choice for UK road and rail tunnel projects where performance and regulatory compliance matter.
S12 compliance to control fire risks
The R-Range is designed to meet S12 standards, covering fire performance in tunnels and transport environments. These require strict limits on how materials burn, the amount of smoke produced, and flame spread.
Low-plastic construction and rubber gaskets approved to EN45545-2 reduce fire risk. Optional ceramic terminal blocks add further fire integrity. This makes the luminaire suitable for rail and road tunnels requiring high fire safety standards.
Maintenance without downtime
Tunnel worksites have limited access. Closures cost thousands, so speed and safety are critical during maintenance.
The R-Range addresses this with tool-less entry, allowing quick access to the LED optic assembly supplied as a plug-in unit. Technicians can swap the optical part without removing the main housing, reducing time spent at height.
The driver is mounted on a removable steel plate held by two captive fasteners, removable without specialised tools. This modular design helps replace components independently, minimising downtime.
Safety retention catches keep the door secure during servicing, protecting workers in confined or elevated spaces.
Durable for UK conditions
Constructed from 316L stainless steel, the luminaire withstands corrosive environments with a C5M rating for marine and industrial atmospheres. It has an IP66 rating for dust and powerful water jets and IK08 impact resistance to resist stone strikes and vandalism.
Operating between -20°C and +40°C, it suits year-round UK conditions, including winter gritting and wet weather.
Compliance with BS-EN-IEC60598 electrical standards offers assured reliability for infrastructure projects.
Intelligent lighting control
The R-Range works with TRT Lighting’s Lumi-LinQ wireless control system. Operators can remotely monitor energy use and adjust dimming to balance visibility and efficiency.
Adaptive dimming modes optimise energy consumption without compromising safety, ideal for continuous tunnel operation or energy-saving retrofits.
DALI dimming is also available for clients with existing control infrastructure.
Simple retrofit and long life
The luminaire delivers up to 3,314 lumens across multiple power options. It boasts an L90/B10 rated life of 100,000 hours, supporting long-term performance.
Designed for easy replacement, it matches common fixing centres and uses twin cable glands suitable for 3-core 16mm² SWA cables. This simplifies installation in live tunnels with restricted access.
TRT Lighting’s R-Range prioritises safety, durability and ease of maintenance, meeting the needs of UK highways and rail infrastructure where fire compliance and uptime are vital.
