Each street, road, and project have its conditions. Standards and regulations generally show the way, but choosing the suitable optics is time-consuming and complex. Fagerhult is now launching a lens guide that uses AI to find the best lens for every scenario – in just a few seconds.
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.
“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.
An accurate guide
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 optimised 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.
Two million data points
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. At launch, 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.

The flexible office in a new light – the innovative lighting design of the future
The office is a place in constant change, and regardless of how the design, furnishing, and operations look, lighting is an important part of the work environment. However, the path to good light can be winding and inefficient, and many factors must align throughout the construction process through property owners, interior designers, and lighting planning. With Fagerhult's Control Track Versa track system, the flexible office is taking a significant step towards more sustainable and flexible lighting. Cecilia Niva is a product manager and has driven the development of the system. The goal has been to let the lighting of the future for innovative offices take shape, and now new, circular possibilities appear. “The dual track provides completely new freedom around lighting design and allows the light to follow the tenants' wishes and needs. You can easily combine indirect and direct light and reach 300 lux with only uplighting. The track provides the right basic level, totally independent of the luminaires, as well as more solutions for control. For example, you can have common uplights that turn on when someone is in the room, while the direct light at the workplace only turns on when someone sits down there,” says Cecilia Niva. Cecilia citat Today, many luminaires are discarded before the tenant has even moved in because the property owner wants to complete the premises at the same time as the tenant is happy to plan or change the lighting and interior design at a later stage. Control Track Versa is based on a 230V system, meaning each luminaire has its own driver. The system can, therefore, grow and change with the needs of the business, and the luminaires can be reused in a completely new way. “Many of our clients have asked for and will appreciate this. Our focus has always been to create a track system that separates infrastructure and luminaires and makes installation and use independent of each other. This provides benefits for both sustainability and flexibility,” continues Cecilia Niva. Flex office block FAGERHULT PRODUCTION OFFICE Greater flexibility also comes with more efficient use of the luminaires. The track system's easy handling and versatility mean that each luminaire can be moved, adapted, and reused repeatedly throughout its entire life cycle. “Long-term use positively affects sustainability over time and as the business and furnishings change. It also creates great creative space for lighting designers, architects and interior designers.” says Cecilia Niva. Creativity and flexibility During the development of Control Track Versa, one of the goals has been to make it easier for lighting designers, architects and interior designers to plan lighting and create high-quality environments. The track system can be described as a toolbox for lighting, as each lighting component is independent, and you can create lighting environments and effects more flexibly. The VIL luminaire makes uplights and downlights completely independent of each other as they can be mounted along entire rows, which provides an evenly lit ceiling in desired zones. Unlike a 48V system, no new calculations are needed when luminaires are added or moved along the track. “In a way, the track becomes its own infrastructure, offering endless combinations and great flexibility. It provides new opportunities to easily combine indirect and direct light without extensive lighting planning or major decisions before the tenant moves in. It also makes it easier for property owners and tenants to maintain, update and create good lighting environments over time,” concludes Cecilia Niva.
The office of the future — A place of change
Lighting offices has long been quite simple. Go-to solutions with 60x60 tiles, proven calculations, and an even and general light result. The advantage is that everyone can move around and sit anywhere—with the result that the light is not good for anyone. As the way we design and use the office changes, new needs arise regarding lighting. The office is a place for work, meetings, collaboration, and creativity. It follows the development of the business and changes among employees. At the same time, the general work environment in Sweden is regulated by the Swedish Work Environment Authority’s recommendations, and lighting is often designed according to established patterns. Henrik Clausen heads the Fagerhult Lighting Academy and believes that both businesses and employees feel good if the office is a pleasant environment—and that lighting contributes to this. The right light also affects many, but despite that, people often take the easy way out to achieve the work environment requirements. “I’m not saying that 60x60 tiles are bad. But they’re not good either, as the premises get the atmosphere of a rainy day. With well-thought-out flows and the proper lighting, we can create a light environment that resembles daylight and varies between the different parts of the office, and then we feel better,” - says Henrik Clausen. Quote Henrik Clausen But before an office is ready for occupancy, many parts need to fall into place, and lighting is one of them. Lisa Sandvik is a project manager at Tenant & Partner in Gothenburg and works with value-creating and sustainable property development with a focus on offices: “When we changed offices and got good lighting, it became clear how much it adds to the work environment. Nowadays, together with the architects, we like to raise the lighting issue with property owners at a much earlier stage and try to challenge them more.” says Lisa Sandvik. Flexible office bildcollage artikel 1 FAGERHULT PRODUCTION OFFICE At the same time, property owners are often far along in their design, and their processes around procurement and planning are in charge. If the costs are too high, they often settle for changing the lighting in one zone or a couple of rooms. “We have far too little knowledge about light, which is strange when we need it so much. Employees and individuals, as well as property owners, know very little about how light and contrasts affect us in everyday life – and not least in the workplace. Here, we need to learn more together and become better at finding the correct arguments and the right products to present to property owners,” says Lisa Sandvik. Quote Lisa Sandvik All projects involving offices are based on the Swedish Work Environment Authority’s recommendations and directives. But it is often difficult to demonstrate the value of good light. “Partners like us and the architects can convey more clearly to tenants what effects good lighting can have. At the same time, I would like to see property owners take a step forward in wanting to deliver prosperous and well-functioning workplaces. We need to learn more about light in Scandinavia. We have it both with us and against us,” says Lisa Sandvik. A trend that Tenant & Partner see today is that larger employers are advocating for employees to be in the office for a larger part of the workweek. Surveys show that people want to be able to work undisturbed and focused. “We see an increased need for focus rooms and quiet workplaces with good technology and the right ergonomics. Shared spaces are, of course, still needed, but above all, you want to be able to work focused and undisturbed in the same way you can do at home. The office, therefore, needs to be an environment where our employees feel comfortable, feel good, and are productive, and lighting is an important factor there,” concludes Lisa Sandvik.
