Abstract
A low-luminance LED lamp that produces light designed for evening reading, relaxation and sleep. Low melanopic input balanced with high color rendering and a warm Correlated Color Temperature (CCT) produces a light with reduced circadian/melanopic input. An engineered LED phosphor produces a spectrum with relatively low blue and green content. This is balanced with a high CRI and the preference for warm (low-CCT) lighting in the evening.
