They are useful to simulate flashlights, car lights, etc. This kind of light is also attenuated towards the opposite direction it points to.

## Ambient Light
Ambient light can be found in the properties of a WorldEnvironment (remember only one of such can be instanced per scene). Ambient light consists of a uniform light and energy. This light is applied the same to every single pixel of the rendered scene, except to objects that used baked light.
