... The visible power a source emits in all directions is measured in lumens. ... Solid Angle- . ... The solid angle of a light cone is the projected area of the cone divided by the total surface area of the sphere. A solid angle is measured in steradians, where 1 steradian corresponds to the solid angle su btended by a cone of unit slant height and unit projected area. ... Luminous intensity is the flow of luminous energy, or lumens, per steradian. ... This is the rate of flow (lumens) per unit area. ...

Brown J., Cassinelli J.P., Li Q., Kholtygin A., Ignace R. Optically Thick Clumps - Not the Solution to the Wolf-Rayet Wind Momentum Problem? ... 426 , 323-328 (2004) . The hot star wind momentum problem $\eta=\mdot \varv_{\infty}/(L/c) \gg 1$ is revisited, and it is shown that the conventional belief, that it can be solved by a combination of clumping of the wind and multiple scattering of photons, is not self-consistent for optically thick clumps. ...
