Lumens, also called Luminous Intensity, represents the total amount of photons emitted by a light source at any given time. Lumens is not the same as brightness, which is the maximum concentration of photons on a given location. Lumens is non-directional (unlike Candelas). (Summing this up over a surface gives total flux, but a point source has no area so you can't really calculate its intensity.)
