Light Therapy without the risk of eye damage

Light Therapy that's Safe, Comfortable, and Effective

The Superior Light Therapy Lamp
For Seasonal Depression

The Lo- LIGHT therapy lamp provides low intensity light therapy for sleep and mood disorders including Seasonal Affective Disorder (SAD or Winter Depression). Since 1995, the patented technology used in this low-intensity light therapy lamp has provided the benefits of light therapy safely and comfortably, without the risk of eye damage that other light therapy lamps may cause.

For Non-Seasonal Major and Bipolar Depression

In addition to the numerous people successfully using Lo-LIGHT therapy for Seasonal Affective Disorder (SAD) and sleep disorders, Lo-LIGHT therapy lamps have shown dramatic benefits when used in combination with antidepressant medications for non-seasonal Major Depression. Studies published in the most prestigious psychiatric journals have also found properly timed exposure to this low-intensity green light therapy provides rapid and sustained relief of Bipolar Depression, without the use of antidepressants or anti-psychotics. Because of the demonstrated efficacy and lack of adverse side effects, this chronotherapeutic intervention is now being recommended as a first line intervention for bipolar depression in clinical practice.

It's Worth It To Protect Your Vision

It is estimated that 13 million Americans will lose vision as a result of age-related macular degeneration (AMD). Compelling evidence links the development of AMD with lifetime exposure to visible light, particularly wavelengths in the blue portion of the spectrum. While the patented GreenLIGHT technology costs more, recent research indicates that repeated exposure of the eye to high levels of blue light wavelengths, which bright light therapy lamps and blue light therapy lamps emit, advances the onset of this debilitating disease by several years. Sunnex Biotechnologies patented Lo-LIGHT technology provides a safe alternative that poses no increased risk of eye damage.

While some may say that it is not yet proven that bright light therapy will cause macular degeneration, it is worth noting what Herbert Kern, the first person to use bright light therapy person, said in the Sept 14, 2007 issue of Science regarding his developing AMD. After explaining that [bright] light therapy became less and less effective for him over the years as his eyesight faded, he said "Now I can hardly see, and all hell has broken loose" "I have had periods of depression lasting over a year...".

Tested and Validated in Laboratories Around the World

An independent study by the Canadian Defense Research and Development Centre recently confirmed that Sunnex Biotechnologies low intensity green light therapy technology provides the most efficient form of light therapy. This study found that even 5% of the intensity (energy) of light from a GreenLIGHT lamp induces double the physiological response as The Litebook®, a therapy device that primarily emits blue visible light wavelengths.

The U.S. Coast Guard developed the Crew Endurance Management System (CEMS) using GreenLIGHT lamps. Years of trials at the USCG R&D Center has shown that the low intensity GreenLIGHT lamps were an equivalent alternative to "bright light" for light management of circadian rhythms. This fatigue management program now being implemented on commercial vessels in the US and Europe. (See Press) or (See links to the GreenLIGHT System for counteracting night work fatigue)

Sunnex Biotechnologies low-intensity light therapy lamps are currently in trials at a U.S. Naval Medical Center to help correct sleep disorders of veterans with head injuries, and by the U.S. Air Force and the Canadian Defense Research and Development Center for maintaining operational alertness at night.
