A “lumen” is a unit of measure for luminous flux. Luminous flux is the time rate of flow of light. 1 lumen is equivalent to the light flux emitted in one unit solid angle by a one-candela uniform-point source. The lumen is similar to the candela, but differs in that it is a measure of light flux irrespective of direction.
