The lumen is the luminous flux emitted into a solid angle of 1 steradian from a source which has an intensity of 1 candela. In other words, 1 candela = 1 lumen/steradian.
The lumen is a weighted value of watts. The luminous flux of a source is calculated by integrating the product of the spectral flux (power per unit wavlength band) and the CIE V-lambda curve. The integrated value, or area under the curve represents the total lumens from this source.
