In photometry,luminous intensityis a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit ofluminous intensityis the candela (cd), an SI base unit.
