Leading the way for sustainable lighting solutions
In the evolving world of lighting technology, Les Thomas, Lighting Technology Manager at Fagerhult UK, stands out as a leader in sustainable innovation. With a broad technical background, gained through years of overseeing design teams and managing technical support for diverse lighting projects, Les's expertise extends beyond the technical to encompass strategic roles in marketing and thought leadership.
Below, Les shares insights into his multifaceted role, the complexities of modern lighting projects, and the innovations driving the industry toward a greener future.
What does a typical day look like for you?
“My daily responsibilities are a blend of creative and technical challenges, but I really enjoy the creativity involved in lighting, particularly when putting together some of the more architectural schemes.
“My interest in the technical side comes from studying mechanical design at university, but I was also influenced by my father, who was an engineer. A large part of my role involves answering questions and resolving challenges presented by sales engineers and consultants.
“A typical example includes providing guidance on lighting levels for specific environments, such as a recent project for a racecourse. In this case, the team and I had to assess the appropriate lighting levels for various spaces, including a weighing room for horses and jockeys, changing rooms, and an interview room, ensuring that each area met its specific requirements.
“This kind of problem-solving is central to my role, I’m often the final check before a project is forwarded to our team in Sweden for further development.”
Are there any projects that stand out as particularly challenging?
“One of the most complex and rewarding projects I’ve worked on involved using Power over Ethernet (PoE) as the supply method for light fittings, rather than the traditional 240-volt supply.
“This approach required significant modifications to existing fittings, including the integration of special drivers capable of accommodating ethernet cables. The project involved extensive collaboration with the factory to determine the appropriate driver, output, and wiring adjustments for LED boards within the fittings.
“Despite the challenges, the project was successful, resulting in a continuous line of lights adapted for the PoE system—a significant achievement in a demanding technical environment.”
How do you stay at the forefront of lighting technology and standards?
“Lighting technology is constantly evolving, so I stay abreast of developments by being an active participant in specialist lighting groups and engaging with industry experts. I’m also the Honorary Treasurer at the Society of Light and Lighting (SLL), which keeps me connected with the latest industry discussions and developments.
“That role often involves reviewing draft copies of SLL’s publications. So, this involvement with the SLL, combined with regular trips to Fagerhult Head Office in Sweden for group sessions with New Product Development (NPD) teams, ensures I’m up to date with the latest trends and advancements in lighting, particularly around sustainability.”
Are you able to give some examples of sustainability initiatives?
“I think Sweden is slightly ahead of the UK in terms of their focus on sustainability, particularly in terms of energy production and material innovation.
“A recent pilot initiative in Sweden with Norsk Hydro explored recycling aluminium from old light fittings to create new profiles, a process that has proven to be quite complex. Sweden’s work with bioplastics and hemp-based fittings is also impressive and reflects their strong commitment to reducing environmental impact. The UK is gradually catching up, but I think there’s still a lot we can learn from Sweden’s proactive approach to sustainability.”
What are some of the challenges you encounter around adopting sustainable initiatives?
“One of the biggest challenges is helping customers understand the complexities of sustainability data. Producing Environmental Product Declarations (EPDs) can be time-consuming, and even though in the UK we have TM65, a tool that can be used to determine the embodied carbon that a light fitting contains, it still requires significant effort. On top of this, understanding what a ‘good’ number is for a fitting is challenging, and comparing products based on CO2 emissions is difficult due to variations in data collection methods.”
What’s driving innovation and creativity within the industry?
“Rising energy prices have been a driver of change, as people look for ways to reduce their costs. But change has also come about because of new regulations; the ban on fluorescent lamps and the push for higher Energy Performance Certificate (EPC) ratings by 2030 will accelerate the shift to LED lighting and smart controls.
“We’re seeing a lot of innovation in materials used for luminaires, for instance the Superdupertube, which uses hemp, and Kvisten, which utilises reflectors taken from end of life TV sets. Both of these products represent significant progress in material innovation.
“There’s also a growing interest in the potential of a second-hand market in lighting, similar to the automotive industry, where old fittings can be reconditioned and reused -a concept that is beginning to gain traction with initiatives like Recolight’s Reuse Hub.”
Good light through the years
With good light in focus, we look ahead to protect our environment and the prospects of future generations. We take responsibility for minimising our own climate impact, and we gladly share our knowledge with others. Through carefully balanced decisions and wise economic priorities, we can create opportunities, innovations, and solutions that provide light today – and in the future.

Exploring circularity: The only straight way forward
In the drive towards sustainability, the Circular Economy vs. Linear Economy is crucial. The Circular Economy prioritises material reuse and longevity to minimise waste. At Fagerhult, we're committed to circularity, designing products for durability and recyclability. In this series, we'll delve into our commitment with insights from Fagerhult Group brands. First, we spoke with Niclas Thulin, Fagerhult's Sustainability Manager. In the quest for a sustainable and environmentally conscious future, the distinction between the Circular Economy and the Linear Economy has become a central focus. Circularity prioritises maximising the reusability and lifespan of materials and resources, striving to reduce resource consumption and minimise waste generation. At Fagerhult, we believe circularity is the only way forward, and are committed to the development and design of products that both last over time and can be reused or recycled. In this four-part series, we spoke to brands within the Fagerhult Group to find out more about their targets, solutions, and approaches to circularity. First up, we caught up with Niclas Thulin, Sustainability Manager at Fagerhult. What approach do you take to circularity at Fagerhult? We are working to meet Science Based Targets in line with the Paris Agreement’s 1.5 °C target, which is ambitious. To achieve these science-based targets, we have four focus areas: circular solutions, energy efficiency, pure materials and conscious production. ‘Circular solutions’ focuses on how we will make the transition from a linear to circular economy. In terms of targets, our initial focus was to implement circular business models, and the second is to enable products to be repaired, refurbished, reused or recycled. Having these targets in place creates a direction for us when it comes to new product development. Do you design your products with disassembly and end-of-life recycling in mind? How easy is it to disassemble your products for recycling or refurbishment? We’ve learned a lot about refurbish and reuse, and we want to design for circularity. For example, we don’t use glue within our products, we try to think modular wherever possible, and we now not only test how to assemble our products, but also to disassemble, making adjustments where necessary to make them even easier to disassemble. Do you offer remanufacturing or refurbishment services for your lighting products? Our Re:Furbish concept is about giving old luminaires new life. A customer might have an existing solution they want to reuse or decrease their environmental impact from, so they may ask us to upgrade. We use as much from the existing light fitting as possible, whilst at the same time upgrading it so that it’s equally energy efficient and has the same function as a new luminaire. Our designers will put together a prototype based on reusing as much of the materials as possible – for example the body, the glare protector, the reflector – the good thing about using the body is that it is one of the components with the most embodied carbon. A lot of our products were initially designed over 20 years ago, and we have been good at using screws instead of glue, so most of the lights can be recycled or reused. The light fitting can be easily opened up and the electronics replaced with something we called a ‘Re:Furbish kit’ – it’s easy to install and doesn’t take much time. We send it to the customer so they can see the solution, having evaluated and tested it from an energy perspective, producing a climate calculation which the customer can compare to the old solution. What we are trying to do is find a way of minimising impact from the materials but ensure the products are equally or more efficient as a new alternative, whilst maintaining the light quality so that it is still beneficial for the end user, too. How do you ensure circularity throughout your supply chain, from sourcing raw materials to manufacturing and distribution? We take a holistic approach right from the beginning – reducing materials in new product development, making materials thinner, making luminaires smaller, and not over specifying products, so having less luminaries in the same space. Another example of our circular solutions concept is our product Kvisten, launched last year and built from both renewable material and reused plastic. The reflector is made from old TV screens, removed from the TVs at the end of life, then cut to size for their new function by our supplier. Through innovations like this we are trying to implement reused materials in our new product development, and our target is that by 2030 our products will be made of 80% renewable, recycled or reused content. In terms of minimising the impact of transportation, we do the installation on-site, which is a benefit because we don’t need to freight the product to site and back, so we are minimising the impact of transportation. This is only one piece of the lifecycle of course – our goal is for all of Fagerhult’s newly developed luminaries to have an environmental product declaration – providing transparent information about the environmental impact of a product during its life cycle.Fagerhult explores circular process in aluminium recycling pilot project
In a pilot project, Fagerhult and Hydro Extrusion Sweden have explored circular processes for the reuse of aluminium – focusing on efficiency and preserved material properties. With the goal of reusing high-quality, extruded aluminium from end-of-life luminaires in the future, Fagerhult, together with Hydro, has explored the possibility of circular models in a pilot project.“Many of our luminaires have an aluminium body, and we want to ensure that they can be optimally recycled without losing the quality or properties of the material. In collaboration with Hydro Extrusion Sweden, we are now exploring how we can close the loop,” says Niclas Thulin, Head of Sustainability at Fagerhult.Recycling in a new lightThe pilot project was initiated in connection with Norwegian Property's ambition to achieve more efficient energy use at Snarøyveien 30 in Oslo. Fagerhult then saw an opportunity to reclaim a large number of Notor luminaires, and the possibilities of recycling and circular processes were explored.“Reuse was not possible, but since there were a larger number of luminaires, we wanted to make the best use of the material,” explains Niclas Thulin. “When extruded aluminium luminaires are recycled, it is common for the material’s properties to undergo downgrading, and then be used in die casting, for example. In this project, we wanted to close the loop and ensure the qualities of the material by allowing the original producer to process the material again. The pilot project resulted in the aluminium being melted down and reshaped, Niclas Thulin continues. Throughout the pilot project, the focus has been on circular processes and sustainable innovations. The goal has been to take new steps beyond the norm and the expected – and to overcome the major challenge of recycling used extruded aluminium – while preserving material properties.“Aluminium is a uniquely durable metal that can be recycled almost endlessly, but like all materials, it needs to be handled responsibly,” says Kristian Frisk, Account Manager at Hydro Extrusion Sweden. “Together, we were now able to recycle the equivalent of 1,300 kg of aluminium in the pilot project, but the big gain is the insights we will take to future projects.”Long-term solutionsWith a long-term perspective and an aspiration to contribute to sustainable development, Fagerhult has pushed the boundaries of what was previously possible and taken a major step towards meeting the demand for new circular solutions.“Together with Hydro Extrusion Sweden, we have closed the chain and demonstrated that it is possible to create new circular processes where all our aluminium luminaires can be handled circularly in the future,” concludes Thulin.
