<P> In photometry , luminous intensity is 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 of luminous intensity is the candela ( cd ) , an SI base unit . </P>
