Reduce blue light

FlameWarm™ is an innovative spectrum engineering technology designed by Yuji Lighting. We redefined the gene of the LED spectrum to reduce the blue light essentially then to eliminate the risk.

Visually warm as flame

The rich red spectrum of FlameWarm™ is based on Yuji LED phosphor technologies that provide a unique color of “visually warm”, bringing a cozy feeling psychologically.

Melanopic/Photopic* matters

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.

M/P ratio = 0.099

The FlameWarm™ mode of the SERENITY offers the M/P ratio down to 0.099, which is even significantly lower than a candle. The ultimate M/P ratio proves the FlameWarm™ mode promotes the melatonin secretion greatly.
