  • Circadian Zirc™ LEDs deliver evidence-based energy efficient circadian lighting solutions. Our spectrally
    engineered NightSafe™ LEDs are the only UL Verified LEDs that emit less than 2% blue content at night
    and our DaySync™ LEDs deliver over 20% blue rich content during the day to synchronize and
    strengthen circadian rhythms.
  • Less than 1/5th of the blue content during evening and night of color tuning lights, even when they are
    tuned to 2700K.
  • Intelligent DynamicBlu™ Spectrum Control System utilizes a pre-programmed astronomical clock for the
    life of the fixture to optimize the light spectrum over 24-hour cycle, automatically adjusts for longitude
    and latitude.
