The first studies with bright light therapy were conducted by Dr. A.J. Lewy for the treatment of seasonal depression, also known as Seasonal Affective Disorder [SAD] and Winter Depression. Numerous studies have indicated that depressive symptoms in people suffering from SAD could be relieved by bright light therapy, which influenced the human body clock to make up for the shorter winter days.
The first clinical trial of Sunnex Lo-LIGHT lamps was also conducted on winter depressives by Dr. A. J. Lewy. The trial demonstrated that the low intensity of Lo-LIGHT lamps influenced human circadian rhythms in the same manner as bright light therapy lamps.
Researchers have now shown that Lo-LIGHT lamps light can also alleviate non-seasonal major depression and bipolar depression. In several studies using light therapy to regulate the internal clock, or "chronotherapy," has provided sustained, effective relief for people suffering from non-seasonal major and bipolar depression.
Pioneering studies using Sunnex Biotechnologies Lo-LIGHT lamps published in the Journal of Clinical Psychiatry and the Journal of the American Medical Association (JAMA) demonstrated the effectiveness of chronotherapy for non-seasonal depression. The low-intensity GreenLIGHT from a Lo-LIGHT lamp was found to induce large phase shifts in the body clock, which researchers tied to the dramatically beneficial results of these studies.
According to the JAMA study using Lo-LIGHT lamps "repeated total sleep deprivation (TSD) and light therapy (LT) caused rapid and sustained antidepressant effects in a matter of hours or days" without side effects.
The Journal of Clinical Psychiatry study found that most of patients suffering from bipolar depression sufferers who received 1 week of treatment with sleep deprivation and exposure to a Lo-LIGHT remained symptom-free for the entire 9-month follow-up period.

Another study found dramatic benefits from the use of Lo-LIGHT
therapy lamps in treating sufferers of severe major depression in combination with antidepressant medications. The authors
chose the safe low-intensity Lo-LIGHT lamps using
GreenLIGHT technology for these studies because antidepressant medications and lithium make eyes more susceptible to
