The length and width of the spotlight together do control the shape of the infinite cone in space that is illuminated by the spotlight.The brightness of the light from the spotlight remains constant, even as you move away from the tip of the cone.The cone for the spotlight represents the direction of the light, not the range of the light.Spotlights with narrower cones produce more detail than spotlights with wider cones.
To move the light without changing its direction, move the dolly point (the control point at the midpoint between the cone tip and the center of the cone base).Turn on the spotlight's control points and move or drag the control points to edit the spotlight's direction, length, beam angle, hotspot angle, and position.
