The Lighting Is On The Wall

Lighting has been enjoying its moment in the spotlight (ha!) since three scientists won the 2017 Nobel Prize in Physiology or Medicine for their discovery of light’s central role controlling our circadian clock. Their important work confirms decades of prior research that suggested when our internal clocks are properly synced with natural light, our bodies fall into an ‘autopilot,’ feeling hungry, sleepy, alert, or energized at suitable times.

The effects of circadian lighting have been measured in three main spaces:


Staff feedback: “People may not realize that the lack of light is making them tired and groggy. You almost have to force them to try it for more than an hour.”

  • Two-year increase in employee retention

  • 19% increase in productivity

  • 1% less sick days

  • +2 hour productivity increases per month

  • Lower levels of depression

  • Higher quality sleep


Student feedback: “I thought we had skylights. I want to be in that classroom as much as I can.”

  • 10% reduction in ADHD related costs

  • 18% improved treatment efficacy for mental disorders

  • A double-digit rise in SAT test scores

Medical Sectors

Staff feedback: “I didn’t think much about lighting before. But I’ve become a true believer after seeing how it’s affected residents. And their family members began asking when they would be getting the lights too.”

  • 1% savings on general health care costs

  • 41% decrease in crying, yelling and agitation in a senior’s care center

  • Seniors consistently slept through the night

  • Non-pharma aid to improve quality of life for dementia patients
