What is Luminous intensity?
In [[photometry]], '''luminous''' '''intensity''' is a measure of the [[wavelength]]-weighted [[power]] emitted by a [[light source]] in a particular direction per [[solid angle]] unit, based on the [[luminosity function]], a standardized model of the sensitivity of the [[human eye]]. The [[International System of Units|SI]] unit of luminous intensity is the [[candela]] (cd), an [[SI base unit]].
