Light is one of life’s most essential ingredients.

Light in nature varies in intensity, spectrum, spatial pattern, and temporal distribution—lighting variables that can also be designed and engineered in the built environment. But to what end? What might we gain by manipulating light? What aspects of life, human and otherwise, are influenced by the momentary, daily, and seasonal variations in light exposure?

As it happens, quite a lot! Lighting influences visibility, alertness, circadian health, sleep quality, learning, mood, and ocular health. We study cause and effect relationships by manipulating light as an independent variable and measuring salient dependent measures.
