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’s new dual driver powers two luminaires simultaneously — and has 49 % lower overall climate impact
Fagerhult’s innovative Twin Dual Driver powers two luminaires with up to 4.8 meters between them. By streamlining the electronics and the product’s material composition, the driver’s total environmental impact is reduced by 49 percent while maintaining safety and making installation and product use easier.With every LED luminaire comes electronics — in the shape of a driver that handles/converts voltage into suitable electricity and maintains safety. This part of the product leaves a significant environmental footprint. Unlike luminaires, which at Fagerhult have continuously been improved to meet high quality and sustainability standards, drivers have not evolved or enhanced at the same pace. Fagerhult now address this with Twin Dual Driver. “Over the years, we have seen one Fagerhult luminaire after the other become meticulously refined, more efficient, lighter, smarter, and made with better materials. But the electronics didn’t evolve at the same pace. We asked ourselves: could we make a change here?” says Lars Eriksson, Product and Application Manager.With innovation and sustainability as driving forces, Twin Dual Driver enables more efficient and environmentally friendly use of drivers. With streamlined electronics, recycled post-consumer plastic in housing – and a 49% overall reduction of CO2e (when comparing EPDs, GWP Fossil A1–A3: Twin Dual Driver and two drivers with equivalent functionality).“Twin results from a few years of hard work, some twists and turns, and a close collaboration with our Finnish supplier Helvar. And now we are standing at the finish line — and the starting point of something new: more efficient drivers, easier installations and less CO2e. It's the definition of a win-win situation. Both the installer and the environment will benefit from it.” says Kenneth Rudenbrandt, Technical Product Manager.Twin Dual Driver enables quicker installations – with fewer luminaires – in large-scale applications and spacious facilities. It comes with cable lengths up to 3 meters, and is equipped with a Quick Connection System that allows tilting of the primary side connection and easier installation in low or narrow ceiling spaces.Synchronised lighting control and safety firstTwin Dual Driver is compatible with the light control system Organic Response. This enables synchronised control of the two luminaires, seamless system integration, and enhanced functionality. As two luminaires are controlled via the same DALI address, each DALI system can double its size compared to the number when using single drivers.Twin Dual Driver is compliant with several of our product families. The most efficient combination available is using two Multilume Re:Think luminaires together with Organic Response lighting control.
The flexible office – 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.
