A short film that documents the experimental testing of the effects of full spectrum light versus fluorescent lighting upon human arm strength.
In this film, John Ott attempts to demonstrate the effects of full spectrum versus fluorescent lighting on human arm strength. When the experimental subject stands in front of a full spectrum shielded light, he exhibits significant arm strength, and Ott is unable to push his arm down. When the same subject stands in front of fluorescent lighting, his arm is noted as, "unbelievably weak."
In a follow-up experiment in front of full spectrum lighting, the subject exhibits similar arm weakness when wearing normal glasses or normal sunglasses, but exhibits much improved strength when wearing full spectrum eyeglasses, thus posing the implication that the route of exposure to the full spectrum light, through the eyes, is the key factor in understanding how full spectrum light is essential for optimal bodily health and function.
In a final experiment, Ott repeats the strength test with his subject in front of the full spectrum light source, receives similar results, and concludes that the preceding experiments did not fatigue the subject.
Although not addressed in this film, Ott argued in lectures that use of fluorescent lighting in schools was detrimental to student performance. He implied that full spectrum lighting was comparable to natural sunlight in its positive effects on human health and performance.
