CIRCADIAN® ZircLight fixtures for industrial and commercial workplaces provide LED light 24/7 with intelligent control of the bio-active blue dosage by time of day and season to boost alertness and productivity, and avoid exposure to the harmful effects of blue-rich light at night.

The secrets to health, productivity and safety lie in the light spectrum. Lighting today is no longer just about task illumination, visual appearance and energy efficiency. Workplace lighting should also protect the health, and boost the productivity of the people who work under them.

CIRCADIAN ZircLights are the result of a major medical science breakthrough. They are the first lights literally designed, tested and optimized for 24/7 use in a world-class medical research laboratory. They provide the proprietary unique spectrum that has been proven to protect and optimize human performance.

Our intelligent CIRCADIAN lighting solutions are designed for cost savings associated with reduced absenteeism, work-related accidents, and health care costs. Isn’t it time you join the hundreds of smart companies who are installing our CIRCADIAN Lights?

The Problem with Conventional Energy Efficient Lights

Most energy efficient lights in the workplace today, including fluorescents and especially LEDs, have a substantial downside health risk in evening and night operations which is now recognized by the World Health Organization (WHO), the American Medical Association (AMA) and the US National Institutes of Health (NIH). Because of their high bio-active blue wavelength content, these widely prevalent lights boost alertness and productivity during the day, but at night they disrupt our circadian clock and health protecting hormones and cause a 35-65% increase in the risk of obesity, diabetes, heart disease, sleep disorders and depression, as well as breast and prostate cancers.
