light which has a location and direction; contrast with ambient light

This is light that is focused and forced to travel in a particular direction either by a reflector or baffle. This may be a spotlight of any sort or a lamp with an opaque shade (not translucent) so that the light goes in a particular direction.

Light that illuminates relatively small areas with a distinct light beam; usually created with spotlight, yields harsh, defined shadows. (See Diffused Light.)

A light illuminating a sector or very narrow angle and intended to mark a direction to be followed.

In rendering, a light that shines evenly in one direction only. Its light rays are parallel to each other, as if emitted perpendicular to an infinitely large plane. Use a directional light to simulate a very distant point light source (for example, the sun). In other software packages, known as infinite light.

an infinite wave of light, always in the same direction, like sunlight

Light source that shines in a particular direction, such as world's main light source

Directional lights such as Default Left Light, brighten based on whether the model surface faces toward or away from the light. Directional lights cast a shadow and are always positioned outside a scene (at infinity).

Light intensity at the center of the beam. Used for flood and spot light bulbs types.
