Each type of light is represented by a different icon in the scene views. Like any other object in your scene, you can select a light and move, scale, or rotate it interactively with a manipulator or with numerical precision by changing the values in the Channel Box. To work with a camera this way, see Use manipulators in the Basics guide.
To direct the light emitted from a light source and otherwise position features of lights (such as a camera’s pivot point), see Show, hide, or resize a light manipulator.
