Cree LED Human Centric Lighting/Circadian Stimulus

Cree LED Human Centric Lighting/Circadian Stimulus devices include the J Series® 2835 3V N-Class LEDs. Utilizing these LEDs, users can adjust the light spectrum for circadian entrainment. The adjustments can encourage good alertness in the morning with a high melanotic ratio or high circadian stimulus lighting environment. In the evenings, if adjusted to a low melanotic ratio or low circadian stimulus lighting environment, the light spectrum encourages a good night's sleep.
