Studies published by leading researchers in highly rated journals have demonstrated that Lo-LIGHT therapy
lamps using the safe and comfortable low-intensity GreenLIGHT technology are as effective as bright light therapy
lamps even though they provide only a small fraction of the light intensity as do other light therapy lamps. The
effect of 350 lux from a Lo-LIGHT is the same as with 10,000 lux of light from a "bright light" therapy lamp.
Studies Validating the Lo-LIGHT as the Best Light Therapy Lamp
The unique low-intensity GreenLIGHT technology developed and patented by Sunnex Biotechnologies does not advance the onset of macular degeneration or damage the retina, which is a concern with the bright light and blue light therapy lamps commonly used to treat Seasonal Affective Disorder (SAD) or sleep disorders.
Researchers at Harvard University's Sleep Medicine Division have confirmed that the green wavelengths
of light provided by Lo-LIGHT therapy lamps are the most effective for regulating the human circadian system.
Harvard used Lo-LIGHT lamps from Sunnex Biotechnologies in studies for NASA's Advanced Capabilities
Division aimed at improving the alertness and performance of night shift workers on earth, as well as for
regulating the circadian rhythms of astronauts on extended missions.

For over 20 years people have been using Lo-LIGHT therapy lamps to combat Seasonal Affective Disorder,
also known by its acronym SAD or as Winter Depression. Studies have now been published in highly rated,
peer-reviewed journals showing that a few days of treatment with low intensity green light from Lo-LIGHT
lamps can successfully treat non-seasonal Major Depression and Bipolar Depression.
Clinical Studies on seasonal and non-seasonal Depression
Experts have issued cautions regarding the risk of eye damage from the use of blue or "blue-enhanced" light therapy lamps
and "bright" light therapy lamps. The Lo-LIGHT therapy lamp is the only light therapy device used for sleep and mood
disorders that cannot cause the retina to "age more rapidly" and advance the onset of Age-Related Macular Degeneration.
The consequences of blindness from Age-related Macular Degeneration (AMD) for users of light therapy lamps can be severe. Bright or Blue light therapy and Blindness.
Lo-LIGHT lamps have been successfully tested in studies to improve the performance and alertness of night shift
workers in operational and simulated work sites by both independent university and military research centers. A counter-fatigue
program for night shift workers, [CEMS] was developed and successfully tested on operational Coast Guard cutters as
well as on commercial vessels operating on both oceans and inland waterways.

Lo-LIGHT lamps using the GreenLIGHT technology have been found to be ten times as efficient as white light therapy lamps in a number of peer-reviewed publications in major journals.
The effectiveness of the low-intensity GreenLIGHT technology stands in stark contrast to a number of studies
which now appear to establish that there is no benefit from the use of blue light wavelengths, or increased levels of
blue light wavelengths, in a light therapy lamp. An important study on the lack of effectiveness of blue light for light
therapy was published in the journal SCIENCE, Translational Medicine. One reason this study is so important is because the
authors include most of the researchers whose earlier work is usually cited as evidence that blue light wavelengths are more
effective than white light for light therapy - a conclusion that this study confirms is not valid.
