My name is Ken Ceder. I’m the Executive Director of Science of Light (SOL), a 501(c)(3) R&D non-profit. On behalf of SOL, I’m pleased to invite you to conveniently, reduce the effects of mal-illumination — the term coined by photobiology pioneer, Dr. John Ott to describe an epidemic of inadequate photo nutrition that’s akin to malnutrition.

“We have finally learned that light is a nutrient much like food, and like food, the wrong kind can make us ill and the right kind can help keep us well.”

“Mal-illumination is to light as malnutrition is to food.”

This little known epidemic has unwittingly been contributing to the physical & mental suffering of millions of people for much too long.

Today, millions of people are literally in the dark about health and suffer from obesity, depression, sleeplessness, and many other maladies. Your health and public health could potentially benefit by simply absorbing sufficient morning sunlight . . .   and it’s free!

Beginning as therapeutic light pioneers (Ott Light Systems, 1987-1997) and culminating with 501(c)(3) non-profit Science of Light — SOL has been on a mission since 2012 to raise awareness of mal-illumination and the essential need for a ‘balanced spectral diet’ to enhance immunity and reduce the risk of disease.

“We are all light deficient and this deficiency may be the source of our physical & emotional problems.” — Dr. John Ott

My life took an amazing turn when I met Dr. Ott, the father of full-spectrum light technology and a fascinating time-lapse photography innovator. Thru the lenses of his cameras, Dr. Ott observed and discovered that sunlight and other types of radiation have a powerful effect on plants, animals, and humans. Since that time biomedical science has filled in many of the gaps in our knowledge about sunlight.

In 2002, researchers discovered retinal cells that detect light but are not involved in vision. These cells link to a center in the brain, the hypothalamic suprachiasmatic nucleus (SCN), which is the site of the body’s master circadian pacemaker. In other words, these neuronal circuits control the body’s ability to sense that it is daytime to turn on serotonin for feel-good alertness and fires-up metabolism, or at nighttime, turn on melatonin to regulate sleep and various other physiological functions.

Being stuck in “biological darkness” due to reduced time in natural light, profoundly affects every body system.

Modern humans, in developed nations, do not spend enough time in natural, ‘full-spectrum’ sunlight that our genes are programmed to respond to. Natural light enhances immunity while too much time indoors under ‘limited-spectrum’ light tends to compromise immunity.

Circadian Rhythm & Brain Regulation

Emphasis on personal hygiene has overlooked the critical need for daily “light hygiene” required to regulate brain chemistry and circadian rhythms that control

  • appetite
  • energy
  • libido
  • mood
  • sleep
  • more

My brother Len and I founded Science of Light with a mission to raise global awareness of mal-illumination.

Inspired by new LED (light emitting diode) technology and the extraordinary, science based health benefits associated with ‘invisible’ near infrared light, our mandate for the last few years has been to develop a simple, leading-edge solution for people when sunlight is not available or who cannot get outdoors.

We worked with engineers to develop a lamp to supply —nutritional light with the characteristics needed to stimulate the SCN in a manner like that of the natural spectral diet that’s essential for optimum metabolism function.

“We can now say emphatically that the function of our entire metabolism is dependent on light.”

— Dr. Fritz Albert Popp
International Institute of Biophysics

As light therapy pioneers since 1987, we originally designed and marketed light systems for seasonal affective disorder (SAD). As you may know, SAD is a mood disorder characterized by depression that occurs seasonally.

The new lamp that we‘ve developed is based on the concept of “daily light hygiene & prevention” and not just seasonal therapy. Unlike any other therapeutic light, SOL PhotoVites powered by SOLshine Photo Nutrition™ includes both the ‘fullest’ spectrum visible as well as essential, invisible near infrared light (NIR) and a trace of UV. NIR reduces the risk of retinal inflammation and augments ATP production for cellular energy and enhanced immunity.

“One-third of the energy your body consumes comes from the food you eat. The vast majority of the energy your body needs to maintain systemic equilibrium comes from environmental infrared light.”

— Dr. Alexander Wunsch, MD, Ph.D., Photobiology Expert
