In photometry, luminous flux or luminous power is the measure of the perceived power of light. It differs from radiant flux, the measure of the total power of light emitted, in that luminous flux is adjusted to reflect the varying sensitivity of the human eye to different wavelengths of light.

Famous quotes containing the words flux and/or luminous:
“Sense is a line, the mind is a circle. Sense is like a line which is the flux of a point running out from itself, but intellect like a circle that keeps within itself.”
—Ralph J. Cudworth (1617–1688)
“[Montesquieu] lifted the veil from the venerable errors which enslaved opinion, and pointed the way to those luminous truths of which he had but a glimpse himself.”
—James Madison (1751–1836)
