As the correlation between light and health is becoming more widely understood, lighting has become a higher priority for various businesses and industries. Implementing healthier lighting into the workplace can help organizations create healthier environments for workers. Lighting is becoming a critical design component in the modern workplace, with circadian lighting serving as the newest consideration.
Most lighting manufacturers are encouraging the use of color-tunable LEDs to try to increase worker productivity while promoting circadian entrainment in offices; in other words, trying to mimic the color of daylight from sunrise to sunset over the course of a day—by allowing the user to change the hue of the white light from reddish warm, neutral white, and all the way to blueish cool— while adjusting the light intensity. These strategies however result in additional costs and complications to the building owner, while adding negligible circadian value—since virtually all color tuning systems use white LEDs that were designed specifically for vision only and do not contain the critical “sky blue” wavelength for true circadian effectiveness.
