Kvisten shows the way – with wood, craftsmanship, and upscaled reflectors from television sets
Kvisten is a unique luminaire where many smaller steps became a big leap towards new, sustainable solutions. With a wooden luminaire body and well-thought-out details throughout, it provides a visually neat and natural feel. And a promise of a brighter future – without compromising with either energy efficiency or light quality.
– Initially, our goal was to create a luminaire with low CO2 emissions and minimal climate footprint. During the course of the work, we questioned every detail in both the process and the luminaire and when we were finished we had re-evaluated everything from the ground up, says Cecilia Niva, Product and Application Manager at Fagerhult.
The result is Kvisten: a luminaire that is both innovative and traditional, built from 77 percent recycled or renewable materials. The luminaire body is entirely made of wood: pine plywood and birch veneer, and no screws or other fasteners have been used.
– Our goal is for all our products to consist of at least 80 percent renewable and recycled materials before 2030. Kvisten is made from certified wood from sustainable forestry and the reflectors are reused from television sets. This is a big step in the right direction, says Cecilia Niva.
To reduce Kvisten’s climate impact even more it can be equipped with Organic Response, a wireless plug-and-play system for light control. This provides just the right amount of light – and at the same time saves energy – based on where and when people are present. Even the packaging is made from recyclable materials and is completely free of EPS and plastic, and as a whole Kvisten provides both a lower environmental impact and the opportunity for more circular processes.
– It became clear that when many people with different expertise are challenged to think in new ways; then really big things can happen, says Cecilia Niva. Many small changes will make a huge difference to the result. The work with Kvisten has given us knowledge, experience and inspiration – and optimism – which we take with us into future projects.

Lukke ringen – og forlenge armaturens livssyklus
Konseptet med å gjenoppbygge gamle armaturer for å spare materiale og energi, blir stadig mer populært. Av og til trengs det bare litt kjærlighet og teknisk kunnskap for å få en utdatert armatur til å skinne igjen. Vi møtte Emma Hallman, Mathilda Holl og Andreas Ekslätt, teamet bak ReLight hos Fagerhult, for å snakke om utfordringene med å finne løsninger som tar gamle armaturer inn i fremtiden. Hos Fagerhult preges alt arbeid av en dypt forankret innovasjonskultur. Det kan hende det skyldes grunnleggeren Bertil Svenssons fokus på å løse utfordringer med til tider begrensede midler – og nysgjerrighet og engasjement. I motsetning til i dag er det ikke sikkert at bærekraft var et kjent begrep på den tiden. Men å bruke ressursene våre på en bevisst måte og ha som mål å levere høy kvalitet har alltid kjennetegnet Fagerhult. I dag har et nytt fokus på sirkularitet fått oss til å tenke nytt og gjort oss bevisste på å finne løsninger som varer lenge. Fagerhults Bespoke Lighting Solutions-avdeling (BLS) har utviklet unike armaturer og tilpassede løsninger i mange år. Derfor er vi godt kjent med å renovere og oppdatere gamle armaturer. Men målet om å gjenbruke og gjenoppbygge gamle armaturer for å redusere klimapåvirkningen har økt over tid. I denne prosessen blir eldre design og teknologi oppdatert ved hjelp av moderne løsninger for å dekke morgendagens krav. Sitat ReLight de gamle armaturene dine For ReLight-teamet hos Fagerhult finnes det ingen uvanlige spørsmål eller umulige løsninger. Hver eneste dag håndterer de forespørsler om spesialutviklede belysningsløsninger for prosjekter fra Fagerhults markeder. Prosessen er kompleks, men over tid har de funnet ut at enkelte prosjekter er perfekte for å gjenbruke gamle armaturer i stedet for å investere i nye. «For oss er kjernen i alle ReLight-prosjekter armaturens kvaliteter når det gjelder belysningskomfort, sikkerhet og estetikk. Ved forespørsel beregner vi også for å finne ut om – og hvor mye – vi kan redusere armaturens totale klimapåvirkning gjennom livssyklusen.», sier Emma Hallman. I ReLight er det en uttalt vilje til å spare materialer og energi, og til å gjøre en innsats for miljøet ved å oppdatere armaturene. Men ikke alle gamle armaturer kan få evig liv. Noen er utdaterte og bør resirkuleres i stedet for å renoveres. Img «Hvis omstendighetene ikke oppfyller kravene våre og armaturene ikke kan gjenoppbygges, går vi ikke videre med prosjektet. Vi går aldri på akkord med armaturens belysningskomfort, kvalitet, sikkerhet eller uttrykk hvis vi ikke kan oppnå en førsteklasses løsning», sier Emma Hallman. Hos Fagerhult er sikkerhet og kvalitet de røde trådene som forbinder alle produkter. Og ReLight er intet unntak. Gjennom hele prosessen er CE-merking og testing avgjørende faktorer. «For å sikre den totale kvaliteten er den oppdaterte armaturen CE-merket i sin helhet før levering. Vi ønsker også å gjøre installasjonen på stedet både smidig og rask, og det nye settet er så nær en komplett armatur som mulig», sier Andreas Ekslätt, Design Engineer.
New technology and intelligent control pave the way for tomorrow's outdoor lighting
All electric light is produced by - and for - humans. Research is now focusing on some important questions: Is our lighting of outdoor environments at the expense of other species? And how can we create a safe environment in balance with the ecosystem and with minimal light pollution? Outdoor lighting prolongs the day and is needed to provide a sense of safety and security, and to create attractive environments even when it is dark. However, light that is improperly directed, used at the wrong time of day, or lacks purpose can be considered light pollution. In addition, it is a waste of energy, and can negatively affect human well-being and animal habitats. “We are in the midst of a rapid development, where biodiversity is threatened,” says Henrik Sandqvist, Product and Application Manager Outdoor Lighting, at Fagerhult. “This happens largely because of humans, and lighting is a contributing factor. Some animals are attracted to the light and others avoid it, which can create an imbalance in the ecosystem.” HENRIK SANDQVIST, PRODUCT AND APPLICATION MANAGER OUTDOOR LIGHTING AT FAGERHULT Today, however, there are limited standards stipulating which lighting should be used where and when. Bioinclusive Lighting involves providing light that is good for people’s well-being and urban development – with as little impact on biodiversity as possible. “As a luminaire manufacturer, we are aware that we contribute to the increase in the amount of light. That is why we can also be part of the solution. We follow the research and guiding standards, and we listen to those who know more than we do. We want to stay ahead, and we always have Bioinclusive Lighting in mind in our product development. Our luminaire Evolume 1 has also been used in a joint study run by the University of Gävle and RISE, and we are happy to collaborate with others to find tomorrow’s solutions.” A darker light environment Around 80 percent of the world’s population cannot see a starry night sky. The reason is ‘skyglow’, which is caused by artificial light shining into the sky. The phenomenon is difficult to measure, but like other light pollution, it can have negative effects on humans, animals, and the environment. “Just as we turn off the lights when we leave a room, outdoor lighting should also be turned off or dimmed when people are no longer in the vicinity. Here it becomes very clear that the right light, in the right place, and at the right time plays an important role.” Henrik Sandqvist sitat Since lighting can affect species’ habitats, the ecosystem needs greater consideration in lighting design. When replacing or installing new lighting, it is important to ask: What is the purpose of the lighting? How does it affect the environment, people, animals and nature? “Our basic idea is that all lighting must have a purpose, and the right character and strength. The amount of light must be commensurate, and it must only directed where it is needed. Since the nature of light is governed by its spectral distribution, we want to avoid light in the lower wavelengths. The general recommendation is therefore to use as warm a light as possible. ANNIKA JÄGERBRAND (UNIVERSITY OF GÄVLE), MARIA NILSSON TENGELIN (RISE) AND HENRIK SANDQVIST (FAGERHULT). Adaptive lighting can also adjust the light intensity and spectral distribution, and time control and presence control enable lighting precisely when needed. “This is nothing new, and nothing we will solve today. But a good place to start is to use a lighting designer with good knowledge of outdoor lighting and who considers the whole when devising a solution. We will continue to focus on finding an inclusive approach to create light for people that is in balance with the ecosystem,” concludes Henrik Sandqvist. Product in focus: Evolume The Evolume luminaire series has good light comfort, and is now available with more options and colour temperatures: 2700K, 2200K and PC Amber as well as adaptive light. This allows the intensity, wavelength distribution, and light distribution to be adapted based on need, time, and presence, and with more consideration for animals and nature.
