Clinical Studies conclude that the low-intensity Lo-LIGHT Lamp
with GreenLIGHT Technology is the Best Light Therapy Lamp

Independent researchers confirm: the Lo-LIGHT "Best Light Therapy Lamp"

Lo- LIGHT therapy lamp 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

Harvard University

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.

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.

GreenLight vs Blue Light

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.
