A drop shadow gives the illusion that the object is floating in front of or above the surface. The drop shadow on the light (upper left) doesn't help to anchor the light to the wall (visible or invisible).

With a cast shadow, the shadow stays attached to the base of the lamp while the rest of the shadow skews away from the lamp and onto the wall. The shadow makes the flat photo appear three-dimensional but not just floating in space. The upper right and two bottom images show just some of the possible cast shadows including solid and fading, hard and soft edges.
