I am a little confused about how radiant flux relates to solid angle W. Thank you!

Radiant flux measures light in terms of Watts. To compute flux, we consider all photons incident on a finite patch (area > 0) and coming from a finite wedge of directions (solid angle > 0). For example, the wedge can represent the hemisphere of possible lighting directions falling onto a patch.
