The Target parameters allow changing the position to where the light rays are emitted in the 3D space without moving the light itself. Just as a camera a light's default position is located at X,Y,Z = 0,0,-25.

The reason for the units of the position parameter lies in the following: one screen width is always 16 units wide, the height is calculated by the aspect ratio. A 4:3 display is 16 units wide and 12 units high, a 16:9 display is 16 units wide and 9 units high.

Lights in Pandoras Box have no attenuation, which means that their intensity is not a function of the distance from a light source to an object's surface but is always equally intense. Thus, the target position does only affect the angle of incidence, i.e. how steep the light shines on an object. The second parameter influencing the angle is the source position. The affect of the angle of incidence is described here in detail.
