Tunable white LED lighting, unlike any other sort of lighting, communicates directly to our thoughts, not physically but intellectually. Because we can change the color temperature of a tunable white LED lighting fixture, we can tailor it to the surroundings or even the time of day. That way, we can align the light with our circadian rhythm to better match the gradual dimming effect that humans experienced for eons living in the wild, underneath the sun during the day and underneath the moon at night. The days of blazing, overbearing lightbulbs, their insistence on casting the same brilliant beams down on people regardless of appropriateness, are long gone.

Tunable white LED lighting is a revolutionary style of lighting that integrates numerous illumination sources. The shifting or tuning described here would be impossible without these numerous sources. Only by making particular alterations, such as shutting off one LED and turning on another, can we generate the spectacular effects for which this sort of lighting is famous. Tunable white LED lighting, a wonder of both engineering and human psychology, has the potential to revolutionize the world in ways that no other type of lighting has since the introduction of incandescent lightbulbs to the market in the nineteenth century.
