HCL according to Fagerhult

There is no standard

Following a scientific breakthrough in the early 2000s, research regarding the importance of light for human biology and well-being has gained momentum. There has been considerable interest in commercialising this research, particularly in the lighting sector. The phrase Human Centric Lighting is used as a generic term nowadays, but there is no standard that defines the concept or governs its use. As a result, each supplier has its own way of interpreting and developing solutions based on the research. This can be a challenge for customers, architects, lighting designers and other stakeholders, as it is difficult to compare HCL solutions from different manufacturers. That’s why here at Fagerhult, we have chosen to be clear about what Human Centric Lighting means for us.

Our definition of Human Centric Lighting

Ever since Fagerhult was founded, we have endeavoured to create lighting that makes day-to-day life better for people. We develop energy-efficient lighting solutions offering a high level of visual comfort, putting the individual at the centre and never compromising on human well-being. With Human Centric Lighting, we are continuing to build on this tradition.

CIE is currently developing a standard (17-29-028) entitled Integrative Lighting. This describes Human Centric Lighting as lighting that “specifically integrates both visual and non-visual effects and provides physiological and/or psychological benefits to humans”. We support this description, and we have chosen to clarify it through our definition of HCL:

• Fagerhult’s definition of Human Centric Lighting is lighting that balances the visual, biological and emotional effects on humans. We therefore apply a holistic approach in which we take into account aspects related to human vision, physiology and psychology.
• Our lighting solutions are evidence-based and incorporate seven different factors: vision, performance, concentration, alertness, mood, general health and well-being.

HCL can never be a product

When done correctly, Human Centric Lighting can make a difference to people’s physical and mental health by supporting a well-functioning circadian rhythm. Biologically, the principle is based on measurable hormone levels in the human bloodstream. Nature and technology have provided us with a fantastic opportunity, but this opportunity also entails a substantial responsibility. We also want to be clear about the fact that Human Centric Lighting is not one specific product, such as a luminaire or a control system. Human Centric Lighting is complex and requires tailored solutions that are based on the specific environment and the opportunities, challenges and needs of the people who spend time in it.

All this starts with sleeping well at night.
