TRT Lighting Ltd (Thorlux Road and Tunnel Lighting) is one of ten companies within the FW Thorpe Group, and evolved from parent company Thorlux Lighting. Building on more than 85 years of experience, TRT designs, manufactures and supplies sustainable and environmentally friendly performance lighting products for the road/street, tunnel and exterior lighting markets.

LED lighting solutions bring another dimension to how roads, streets, tunnels and general exterior spaces are illuminated. TRT’s ability to understand and adapt to the needs of its customers ensures that developed products are technically and mechanically sound and provide energy efficient, long-lasting lighting solutions with excellent returns on investment.

The company is also committed to reducing obtrusive light and light trespass in order to protect the night sky from light pollution. This preservation is critical not only for the well-being of people and wildlife, but also for scientific and astronomical purposes. A range of TRT products can be used in dark-sky applications, thanks to their International Dark-Sky Association approval.

TRT Lighting are proud to manufacture its products in the UK. All luminaires being rigorously tested to all relevant global and regional standards using in-house testing facilities.

Accreditations & Compliances

TRT Lighting achieved the latest ISO 9001:2015 quality management system certification by the BSI, this ensures the company meets customer and regulatory requirements when providing a product and/or service.

The company is assessed to BS EN ISO 14001:2015, an international standard that sets out the requirements for an environmental management system. It helps organisations improve their environmental performance through more efficient use of resources and reduction of waste.

ISO 45001:2018 certification has been awarded to TRT. This standard specifies requirements for an occupational health and safety (OH&S) management system, as well as guidelines for its implementation, to enable an organisation to proactively improve its OH&S performance in preventing injury and illness.


The Thorlux and FW Thorpe Plc names are synonymous with quality all across the world and this is reinforced by The Group having a major UK export customer base, representation and capabilities, supplying luminaires and control systems to over 60 countries worldwide.

Building on this experience, and continuing the desire to embrace new technologies, TRT Lighting evolved from Thorlux in 2012 as the specific road and tunnel lighting specialist division of the Group with a core focus of developing lighting products for roads and tunnels using only LED technology.

Five years ago saw our first major overseas project, with the installation of TRT tunnel luminaires in the high ambient, arduous environment of Australia.

Over one hundred Verso luminaires, which interfaces with a dedicated lighting control system, were supplied. With a colour temperature of 5700K, the units now provide a crisp white light LED solution which improves driver visibility and safety.

With hundreds of thousands of LED street lighting products now installed across the UK road network and numerous, fully automated tunnel lighting systems complete, TRT has now expanded on its export horizons with representation in Ireland, Norway, Germany, The United Arab Emirates and Australia.


At TRT, we supply luminaires to the road, tunnel and exterior lighting markets that deliver an abundance of key features and benefits to both the customer and of course the general public. Light efficiency and control are two of our main areas of focus when designing and developing our products. All luminaires from TRT have long projected lifetimes, even when exposed to the rigorous physical demands of both external and road tunnel environments, and incorporate a number of unique mechanical and technical features, purposely developed to aid installation, maintenance and the ongoing through life costs.

Our products not only provide the potential to significantly reduce maintenance and energy costs for our customers but also, especially when considered with our accredited Carbon Offsetting Program, minimise the environmental impact that the manufacture and supply of the lighting products can have.

We are committed to ongoing sustainability targets with product longevity therefore being a key consideration in all that we do.

Powder Coat Plant

2019 saw TRT invest in a new fully automated, energy efficient pre-treatment and powder coating plant which provides maximum flexibility on product colours and finishes. This facility consists of a five-stage pre-treatment plant that cleans and prepares products before being painted. All products are thoroughly washed down and cleaned within this facility to remove all surface contaminants and impurities before the powder paint is applied.

Chemicals used within the pre-treatment processes are free from chromates and iron phosphates and the processes utilise more environmentally friendly chemicals.

The paint powder used to coat the products is a polyester powder coat with a smooth semi-gloss finish.

During the powder coating process, overspray powder is immediately recovered and reused. The risk of powder escaping and contamination of the surroundings is reduced. This results in a cleaner and safer environment as well as increased efficiency.

All products painted within this facility pass the requirements of 1000 hour neutral salt spray testing and our internal QA processes ensure that all batches are inspected for paint thickness, surface finish and paint adhesion before being approved and released for use.

SMT Facility

Multi-millions of pounds of investment have seen TRT’s Redditch site develop over the years bringing various processes in-house.

A dedicated clean room was installed in 2017 which houses a state-of-the-art SMT production line producing all LED PCBs and control PCBs used in our luminaires. This allows the company to closely manage and oversee its activities and developments. A placement speed of up to 45,000 components per hour provides a quick PCB sampling turnaround.
