Peer-reviewed studies have shown that Lo-LIGHT lamps using the GreenLIGHT technology have been are as effective as bright white light therapy lamps that provide 20 times as much light intensity.
The unique low-intensity GreenLIGHT technology developed and
patented by Sunnex Biotechnologies cannot advance the onset of macular degeneration or damage the retina, which is
a concern with bright light and blue light therapy lamps commonly used to treat Seasonal Affective Disorder (SAD)
or sleep phase disorders.

For over 20 years Lo-LIGHT therapy lamps have been used to combat Seasonal Affective Disorder (SAD or Winter Depression).
Clinical Studies using Lo-LIGHT Therapy for Seasonal and Non-Seasonal Depression
Experts have cautioned regarding the risk of eye damage from 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
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 AMD.
Lo-LIGHT lamps have succeeded in studies to improve alertness in night shift workers by both university
and military researchers.
A counter-fatigue program for night shift workers, the CEMS program, was developed and successfully tested on operational
Coast Guard cutters as well as on commercial vessels operating on inland waterways and on oceans.

The studies confirming the effectiveness of the low-intensity GreenLIGHT technology stands in stark contrast to the several studies which found there is no benefit from using blue light wavelengths in a light therapy lamp.
A major study confirming the lack of superiority of blue light wavelengths in light therapy was published in
Science. Several of the authors of this study were responsible for earlier studies that led to the widespread misconception that
blue light wavelengths are more effective than white light for light therapy.
The advantages of GreenLIGHT over blue light therapy
In North America, a no-risk rental program is available for some models of Lo-LIGHT. If the unit is purchased within 2 months from the time of rental, all rental payments are applied towards the purchase price.
The Sunnex Biotechnologies Lo-LIGHT phototherapy lamp comes with a five year warranty. Details
