Can red light improve your sleep?
Updated: Nov 15, 2019
Participants received 30 minutes of red light irradiation every night for 14 days. (658nm was administered for 30 min at fluence of 30 J/cm2)
The placebo group did not receive light illumination.

In addition, 3 studies transcranial PBM (shining light directly on the head) suggest a possible hypnotic effect. [2,3,4]
Melatonin also increases potency of other antioxidative enzymes. (2)
"Low intensity red light at night did not impact the pattern of melatonin secretion in this study and is, therefore, unlikely to impact the physiology of circadian or seasonal regulation." (8)
When its dark outside, you only want enough light to be able to see - and you want that light to be red.
That is why all of our lights have multiple power modes. If the LUX is to high it is dark outside it will impact circadian.
