“Kelvin” : The Color of The Sun Sun’s Color Varies During The Day Sun’s Color Affects Our Body’s Circadian Rhythm
Biologic light supports the day/night rhythm
automatically, it promotes and maintains health and performance
“HUMANCENTRIC LED LIGHTING” New LED’s Easily Adjust Kelvin
Adjusting the Kelvin… Affects Our Body’s Circadian Rhythm
Quicker Healing of Patients Reduced Need for Care Due to Stabilization
of the Circadian Cycle of Older People Orientation and Prevention of Falls Due to
Increased Physical Performance Reduction of Medication
Secret Ingredient
“Johns Hopkins identifies mammalian intrinsically photosensitive retinal ganglion cells (ipRGCs) & melanopsin as affecting non-visual photic responses, such as behavioral responses to light, pineal melatonin synthesis, sleep latency and pupillary light reflex.”

A Prospective Study of Patients Undergoing Spinal Surgery
The exposure postoperatively of patients who have undergone spinal surgery to increased amounts of natural sunlight during their hospital recovery period may result in decreased stress, pain, analgesic medication use, and pain medication costs
The patients housed on the bright side of the hospital(46% higher intensity sunlight on average) used 22% less analgesic medication in all age quartiles.
