    Circadian lighting

    Improve well-being and light in step with the body’s circadian rhythm

    The role light plays in our day-to-day experience cannot be overstated. Lack of light, and even lack of the right light, has been proven to disrupt the human circadian rhythm, which regulates the daily sleep-wake cycle. This can lead to a variety of health problems—stress, sleep deprivation and depression to name but a few.
    Circadian lighting uses dynamic LED luminaires—tunable white and full-color— and evidence-based lighting recipes (dynamic lighting scenes) to improve mood, performance, and overall well-being.

    Set the tone

    Lighting recipes are specially designed to work in tandem with the body’s circadian rhythm, with each recipe scientifically validated to produce or enhance specific positive outcomes. Use these recipes—which rely on distinctive, slowly-changing combinations of color and intensity—to influence your employees or customers to focus, relax, concentrate, or even wake up effectively and reliably.

    Relax your guests

    Getting your lighting right can be the difference between a rested, happy hotel guest and a tired, frustrated one. Interact lets you create unique wake-up experiences, automatically dim lighting in the evening before bed, and provide low-level illumination on the way to the bathroom at night, minimizing sleep disruption. Let guests personalize the lighting in guest rooms for enhanced comfort and relaxation.
