    3  * Omni Light
     3 * Point Light
    44
    5  * Spot Light (spot/directional)
     5  A Point Light (also known as Omni Light) emits light equally in all directions, like for example an emergency signal flare fired into the sky from a ship in distress.
     6
     7 * Directional Light
     8
     9  A directional light produces infinitely-wide beams of parallel light, it appears to illuminate all objects with equal intensity, as if it were at an infinite distance from the objects so the position of the light doesn't matter, only its direction matters. A good example of a directional light is the sun.
     10
     11 * Spot Light
     12
     13  A Spot Light is a light source which has a cone of effect, like a desk lamp for example. Like a Directional Light, it has a basic direction, but it also has a defined conic volume in which its light can fall and unlike a Directional Light, its position determines what objects it affects. The angle of the cone determines how much of the scene is illuminated.
