Short version
Human Centric Lighting (HCL) adapts brightness and color temperature throughout the day to support circadian rhythms and increase well-being, focus and wellness. From our products with Tunable White, you get dynamic lighting that recreates natural light - cool for energy, warm for calm. Used in homes, offices, schools and healthcare, HCL provides a better indoor environment, adapted to both people and activities. The solutions are easy to integrate, even in existing facilities. When used correctly, HCL can relieve stress, improve sleep patterns and increase concentration. Studies show that customized lighting can have significant benefits for both physical and mental health.
Why light matters more than we think?
Light affects more than just our vision - it controls our circadian rhythm and affects sleep, energy and mood. Yet we spend most of our time indoors, often under static and poorly adapted light. This can disrupt the body's natural rhythm and reduce both well-being and productivity.
Human Centric Lighting (HCL) is lighting design that takes this into account. By mimicking the natural light variations of the day, brightness and color temperature are adapted to the body's needs throughout the day. The result? Increased well-being, better concentration and a healthier indoor environment.
