Human Centric Lighting

The powerful effect of light


All living beings have an “inner clock” called the circadian rhythm, and humans are no exception. In short, this means that we rise with the sun and go to sleep when it sets. The right light at the right time can influence everything from our sleep to how we feel and perform. That is why Human Centric Lighting (HCL) is beneficial for schools, healthcare facilities, offices and industrial buildings.


The Glamox Group has extensive experience in tailoring HCL solutions in cooperation with our clients, and we have delivered more than 90 projects. We believe that successful projects stem from successful teams. Together we can achieve an optimal lighting system for your facility. Glamox HCL solutions are WELL Building Standard™-compliant.

Benefits of Human Centric Lighting

Humans are affected by light not only on a visual level, but also on a biological one. When installing a Human Centric Lighting solution (HCL), you reinforce your circadian rhythm, enhancing your cognitive skills and sense of wellbeing. It is also used to provide the ideal visual working conditions in challenging environments.

You sleep better

Improve your sleep quality by adjusting the hormone balance in your body. This is something everyone can benefit from, but it is especially important for adolescents, shift workers, psychiatric patients and people with dementia.

You perform better

Glamox HCL can improve performance by enhancing the ability to concentrate, increasing alertness and reducing fatigue, which in turn can lessen the number of errors made at work.

Light and the human biology

Daylight is the most important “time giver” to control our circadian rhythm. Light is therefore an important contributing factor to our wellbeing. Scientists have been studying the biological impact of light for decades, learn more about how light is used to provide the best possible light for us.

Guiding parameters

When installing human-centric lighting, there are four parameters that require close attention:

HCL spectrum red.jpg


The blue wavelengths of light are its biologically active parts. This means we can use cool white light with wavelengths in the blue spectrum to stimulate the body in the morning, and as a boost when we need to focus and stay alert. In the evening, warm white light can help us relax and unwind.

HCL intensity red.jpg


Research has taught us how much light is needed to influence the biological processes in the human body. When planning and designing a lighting solution, enough light must be emitted to achieve this, while addressing issues such as unwanted glare and energy consumption.

Timing and duration

The morning light tells our biological clock that the day has begun, helping to activate our bodily functions. In contrast, light exposure at night makes it harder to fall asleep. These factors must be considered when planning an HCL solution with a 24-hour cycle.

HCL distribution red.jpg


For light to have a biological effect, our eyes must perceive it effectively. The receptors that affect our circadian rhythm are most sensitive in the lower and nasal part of the eye, so how the luminaire distributes the light is of great importance.

Research-based knowledge

Human centric lighting is a field of research in rapid development, and we at Glamox seek to increase our insight accordingly. Since 2013 we have developed Human Centric Lighting solutions based on the latest research and standards available. To further improve the knowledge of how light can influence people we are collaborating with a number of external research institutions, and support and contribute to a number of studies.
