the lighting power in the most sensitivity range of ipRGCs to help with promoting the melatonin secretion and this leads to relieve, relax naturally from the cozy lighting environment derived from the Well24™ Nite technology.

Low Melanopic/Photopic ratio (MP Ratio) for Well24™ Nite
The Melanopic/Photopic (M/P) ratio measures the stimulative or suppressive of melatonin secretion from a light.
M/P ratio is a scientific and objective index to evaluate if your light holds back or helps with your relaxation.
