The Lo-LIGHT Therapy Lamp
Comfortable low-intensity GreenLIGHT therapy
Independent researchers confirm that GreenLIGHT from Lo-LIGHT lamps
is more effective than blue light for mood disorders and regulating circadian rhythms
Lo-LIGHT lamps found effective in studies by leading light therapy experts including AJ Lewy, J Arendt, CA Czeisler
Lo-LIGHT lamps do not emit blue light that can damage the retina and contribute to vision loss of light therapy users.
Lo-LIGHT lamps emit less than 5% of the light intensity of bright light therapy lamps, making them safe and comfortable.
Lo-LIGHT phototherapy lamps were found to be superior to 10,000 lux white light or blue light therapy lamps.
Lo-LIGHT lamps selected by Harvard University for NASA space project.
Harvard confirms GreenLIGHT wavelengths most effective for light therapy, and human circadian regulation
.In 2022 a group of light therapy researchers in the Department of Sleep Medicine at Harvard university (plus G.C. Brainard), published a paper in PNAS (Proceedings of the National Academy of Sciences) on the effects of several different wavelengths in the visible light spectrum on human circadian physiology, which indicated that the light wavelengths provided by Sunnex Biotechnologies' Lo-LIGHT lamps, i.e. (500 - 510 nm green light, are the most effective light wavelengths for light therapy.
"Examination of the fitted half-maximum value of each irradiance response curve shows that 507 nm light is more effective than 480 nm light at suppressing melatonin and resetting circadian phase"
The spectral sensitivity of human circadian phase resetting and melatonin suppression to light changes dynamically with light duration
Harvard confirms Lo-LIGHT lamps most effective for light therapy and real world human circadian regulation.
.In 2024 the Harvard group, headed by C.A. Czeisler, acknowledged in the journal Sleep Health that in real world conditions, during the initial 90 minutes of light exposure, the human physiological response to light, as measured by either melatonin suppression or by its capacity to shift circadian rhythms, is not in the blue region of the visible light spectrum, as is widely presented in the light therapy literature, but is in the green portion of the spectrum, in the region of the spectrum emitted by Lo-LIGHT lamps. i.e. 500-510 nm.
"given the effectiveness of monochromatic blue-green light (507 nm) at both suppressing melatonin secretion and delay resetting circadian phase ... these findings with green-enriched polychromatic light challenge the oversimplification that blue light is always more effective than green light for inducing circadian resetting in humans."
"In the GREEN light conditions (GG and GS) the ambient room light was generated by ceiling-mounted green, fluorescent lamps (Sunnex Biotechnologies, Winnipeg, MB Canada)" Harvard study with Lo-LIGHT lamps
Between the 2024 and 2022 papers, the Harvard Sleep Medicine group acknowledged that in real world conditions, where subjects eyes are not dilated, and who have not been restricted to very dim light exposure for about a day prior to the therapy, and who use light therapy for less than 90 minutes per session. GreenLIGHT wavelengths are more effective than blue light for influencing human physiology.
Studies confirm blue light wavelengths are not necessary for Effective light therapy.
Because Lo-LIGHT lamps do not emit blue light,
light therapy studies by leading researchers of using Lo-LIGHT lamps,
including A.J. Lewy, C A. Czeisler, J. Arendt, F. Bendetti, published in highly rated journals including JAMA Psychiatry,
J. Clinical Psychiatry, Sleep Medicine, Chronobiology Int., that found Lo-LIGHT
low intensity lamps effective, confirm that blue light wavelengths are not an important factor for effective light therapy.
In studies on light therapy and regulating circadian rhythms, Lo-LIGHT lamps
were found effective even though they provide less than 10% of the light intensity of bright light or blue light therapy lamps. See More at

A superior light therapy lamp
For over 20 years Lo-LIGHT therapy lamps have been used to combat
Seasonal Affective Disorder (SAD or Winter Depression).

Light therapy for night shift workers
Chronobiology can help regulate of the internal body clock through by timed exposure to appropriate light sources. The low intensity Lo-LIGHT can align the internal clock with the work schedule to prevent the deterioration in health and performance of night shift workers, and is adaptable to almost any work environment.
Lo-LIGHT improves night shift alertness and performance.
It's worth it to protect your vision
Some experts continue to express caution regarding the risk of impaired vision from exposure to blue wavelengths of light.
The Lo-LIGHT therapy lamp is the only light therapy
lamp used for sleep and mood disorders that does not emit blue light which can contribute to retinal damage and
hasten the onset of Age-Related Macular Degeneration(AMD). Light therapy users who develop AMD may not only lose
their vision, but find that light therapy is no longer beneficial.
More on How bright and blue light therapy lamps can hasten the onset of age related blindness
For Therapists and Eye Specialists:
We have several technical pages on aspects of the risk of retinal damage and AMD from the use of bright and blue light therapy lamps. Please see the section with this heading at bottom of the page discussing ocular risks the from the use of bright and blue light therapy lamps at the previous link.

"I am very satisfied with the green light. I found it to be very helpful in alleviating my symptoms of SAD"
E.A. Phd. MB Canada
"The white light is effective, however, I looked forward to the green light ...Using the green light was a pleasure rather than a discipline."
V.R. OR USA
"I thought the lamp was great. I felt calmer and less sleepy during the day...it was easier to get up in the morning"
J.W. B.Pharm. KS USA
"I use it after coming off the night shift. It helps in shifting me back and helped decrease the frequency of my migraine headaches."
M.S. RN WI USA (For night shift work)
"I will recommend your units to anyone who has DSPD, as I did, because quite frankly, IT WORKS!"
R.P. PA USA
"I am really pleased that we found your product. My son has been struggling with his sleep cycle for years due to late-stage Chronic Lyme Disease and he is now getting up at about 9:30 am and going to bed about 12:30 am. This is a huge improvement from where he started and we have every reason to believe it will continue to get better. Thanks for doing what you do!!"

"Years ago, I was diagnosed with a severe case of the sleep disorder DSPS and I have been suffering from it all my life....In 2008, I started taking advantage of blue light technology, but 2 years later I had some problems with my eye sight. I have now been using the green light instead of the blue one for a few months, and it has done wonders for me. Not only am I no longer worried about my eye sight, it is also even more effective than the blue light was, in my personal experience. My work days are obviously a lot more productive as well and by merit of that alone, the green light has already paid for itself.
M.Z. Brazil
"I recently retired and almost immediately started suffering from insomnia. Then fall came and I also fell into a depression (SAD). I started to use green light therapy, and the results were simply amazing. Within one week my insomnia and SAD were completely under control. I now get up with no problem, have lots of energy throughout the day, and am in a good state of mind. I am very happy with Green Light therapy."
B.J.S. MB Canada
"I felt less depressed..The very first time I used the lamp I felt very energized." "It reminded me of my previous job when I worked outside in the sunshine. When I used the lamp I felt like the sun was shining on me."
