At Fagerhult, optics are in constant focus, and a lot of effort and knowledge is put into developing and refining the lenses — to make the lighting along the roads as efficient and sound as possible. However, with more advanced optics, greater complexity, and a growing product range, the choice of lenses also becomes more difficult. To simplify light planning, Fagerhult is now launching a lens guide, a new AI tool that helps light planners take the shortcut to the right lens for every scenario.
“Those familiar with our luminaires and lenses are likely to know which lens and optics to choose to meet specific scenarios. But if you don't have this knowledge, you can now use our AI tool to find out which lenses meet the requirements and provide the best and most efficient solution,” says Henrik Sandqvist, Product and Application Manager Outdoor Lighting at Fagerhult.
The tool is based on predictions and is best used as a complement to Dialux. All the user needs to do is fill in information about pole distance, mounting height, overhang, and road width, as well as which national standards that must be achieved. With one click, the tool presents complete data for three possible alternatives: the most efficient solution, the overall most optimized solution and the solution with the best G class.
Henrik Sandqvist states that the results may vary depending on how the products are configured; however, it generally serves as a very accurate guide.

Martin Hübert, CAE engineer at Fagerhult's Optics Development, in collaboration with Jönköping University, is behind the tool's development.
“We who develop optics sometimes get questions about more complex scenarios, but giving general answers is difficult. However, we know what our lenses could achieve and we always want to offer the best solution for each project. I have previously thought about how we could make light planning easier by making our internal tools more accessible to our customers. In collaboration with the Department of Computing at Jönköping University, the idea of AI came up, and the pieces fell into place,” says Martin Hübert.
The over two million data points used are split into two parts: one that trains the AI models and one that verifies them. Based on these, a model is created for each parameter you want to predict, and the user gets suggestions on which optic is best for the scenario filled in.
“The user then needs to ensure the proposed options in Dialux. Compared to testing one's way between several possible alternatives, this is a significantly more efficient way of working. Many often choose a lens out of habit if it meets the requirements. The lens guide considers a lot of data and always suggests the best lens for each scenario and choice. The matches are at a very high level, and we also see other significant opportunities to work with AI to refine our optics and support our customers in more ways in the future,” concludes Martin Hübert.
The lens guide, a part of Fagerhult Configure
The lens guide uses AI to make predictions and present three options for your specific scenario when light planning outdoor applications. When launching, the tool can select optics for a two-lane road. There are plans to expand with additional functionality. The lens guide is best used as a complement to Dialux. The tool is part of Fagerhult Configure and can be used by logged-in or non-logged-in users.

Fagerhult sets new industry standard: switching to the latest LED technology
Fagerhult is setting a new standard in the lighting industry and switching to the latest LED technology in its luminaires. One outcome of this is that the operating time is being doubled from 50,000 to 100,000 hours. “We want to make it easy for our customers to make the right choice, both for their wallet and for the environment,” says Marcus Fagerlind, Technical Manager for Smart Lighting at Fagerhult. Fagerhult is now taking the next step in the evolution of lighting technology. Going forward, the luminaires will be supplied with the latest generation of LEDs featuring Flip Chip technology. For our customers, this means lighting that offers higher energy efficiency, lower energy consumption and superior light quality – while also doubling the operating time. “Flipped” technology Flip Chip is a premium-segment LED chip that is based on proven technology. The thing that sets Flip Chip apart from standard LEDs is its design. Image gallery: LED-chips Section: Flip chip headline “An LED chip is made up of several different layers of material that determine the light’s wavelength and properties. A traditional standard chip is built like a cake with multiple layers, which the light shines up through from the bottom. Electrodes are attached at the top of the ‘cake’ and connected via gold or silver wires. Since these contact surfaces are located at the top, they also block some of the light, which affects the light output and, consequently, energy efficiency. These metal wires are also subjected to ‘stress’ in the event of temperature changes, making them a potential source of failure that can affect the working life of the LED chip,” explains Marcus Fagerlind: Marcus Fagerlind, Technical Manager for Smart Lighting at Fagerhult, at the Experience Centre in Habo, where lighting solutions are explored and demonstrated. In a Flip Chip, the cake is simply turned upside down, with all the contact surfaces at the bottom of the chip. This allows the light to flow freely, and the chip operates more efficiently without interference. Placing the contact surfaces at the bottom also helps avoid potential sources of failure in the connecting wires. As a result, the Flip Chip technology delivers a product that is both more efficient and more robust. Significant energy savings Equipped with the latest generation of Flip Chip LEDs, Fagerhult’s luminaires will increase energy efficiency by 5–10 percent, depending on their previous configuration.An efficiency improvement of this magnitude naturally has a significant impact on energy consumption and operating costs, but also on the system’s climate impact.“In an uncertain world, with energy crises following hot on the heels of each other, it has become even more important to accelerate the green transition – and to ensure that energy efficiency, economic considerations and environmental concerns go hand in hand. Every kilowatt-hour counts,” says Marcus Fagerlind.The operating time is also being extended – from 50,000 hours to 100,000 hours. A doubling of the working life, in other words, which makes Fagerhult’s luminaires a safe and profitable investment for the future. All upgraded luminaires will also have a constant light output, providing secure, stable, high-quality light throughout their working life. Extended lifetime from 50,000 to 100,000 hours, with stable, high-quality light throughout. New industry standard The switch from standard LEDs to Flip Chip covers the majority of Fagerhult’s Indoor range. Luminaire models that already feature Flip Chip will be upgraded to the latest generation of Flip Chip, as will all models that were previously equipped with standard LEDs. This change can improve the energy efficiency of the luminaires and reduce electricity consumption, meaning that with a small amount of effort, it is possible to achieve a very big impact.That sounds like a major change, doesn't it? “Absolutely,” says Marcus Fagerlind: “But this approach – daring to take the lead and make the tough decisions needed to bring about change – is very much part of Fagerhult’s DNA. We have never compromised between ergonomics and energy efficiency, choosing instead to drive our innovation efforts to find new solutions. This is an obvious step we have to take, not least for the sake of the climate. We want to take our share of the responsibility. This ought to be the industry standard.” Platinan in Gothenburg features 12,800 luminaires in one of Fagerhult’s largest innovation projects - demonstrating how the latest LED chip technology supports improved light quality and energy efficiency. Does this mean that the luminaires will become more expensive?“That’s exactly the point. We don’t want our customers to have to choose between what’s good and what’s actually even better. We also don’t think they should have to choose between strong finances and climate considerations. The cost of the upgrade will not be passed on to customers in the form of more expensive luminaires, but will be financed through the logistical benefits that the change will bring. With our pricing model, our customers gain access to the latest technology – at the same price as before.”
Innovation in every fold – Wrapped exceeds in engineering brilliance
As sustainability is no longer a choice but a necessity, innovation must begin with the question: What if we did things differently? For Fagerhult’s R&D team, that question became the spark behind Wrapped, the world’s first pendant luminaire made of cardboard. Traditionally, pendant luminaires are built with metal frames, which is a durable, familiar, and safe method. But the team behind Wrapped wanted to explore another path. Together, they decided to find out if they could create a luminaire that not only performed at a premium level but with minimized environmental impact. After thorough consideration, Solid board – a renewable and recycled cardboard material that had previously only been used in hidden components – now plays the leading role. Wrapped is more than a luminaire, it’s an exploration of forward-thinking and creativity. With no ready-made solutions to lean on, the design team had to start from scratch. Every element, from the construction to the mounting, was looked into and the result is a luminaire that’s both technically solid and environmentally conscious. Gallery: Wrapped details The luminaire body is made of up to 65% recycled cardboard and folds together with high precision cut-outs that fit perfectly. Engineering elegance Wrapped’s body is composed of two primary parts: the inner body and the outer body, both designed to work in harmony for strength and stability. The outer body is held together by a rib made of 75% recycled post-consumer aluminium, locking the folds in place and ensuring shape retention. Its end caps are made from 100% recycled post-consumer plastic and snap into precision-cuts, securing the structure without the need for screws. The junction box is snapped into place and the driver is mounted using small clips, made from recycled post-consumer plastic. The LED board is mounted onto the lens, protected by a cover of Solid board, and the entire light module is locked into place with a louvre. The result is a seamless, screw-free construction that embodies thoughtful design. Design with purpose Fredrik Beckius, Design Engineer at R&D, reflects on the journey:“The challenge was working with a material that we had never used for a pendant luminaire before. We couldn’t mount components the usual way, so we had to find alternative solutions.”Martin Gustafsson, also a Design Engineer, adds:“We had to find a way to produce the luminaire cost-efficiently, both for us and our suppliers. Every design component had to serve more than one purpose.” This dual-purpose thinking is evident throughout Wrapped’s design. It’s not just about aesthetics or sustainability – it’s about engineering brilliance and making every part count. Quote: Martin Gustafsson Sustainability without compromise Wrapped is manufactured in Fagerhult, Habo, using locally sourced recycled and renewable materials. It’s a product born from Swedish innovation, rooted in the legacy of previous sustainable designs like Multilume Re:Think and Kvisten. Unlike many eco-conscious products, Wrapped is quietly confident – and sustainable in its DNA. With high-precision cut-outs, a stable construction, and rigorous testing throughout the process, Wrapped meets all quality standards without compromising its environmental ethos.
