Light is the base class for all light sources: see AmbientLight, DirectionalLight, PointLight, Spotlight, and ProjectorLight. A Light defines the properties of a light source, like color, intensity, extent, etc. However, it does not define the position of a light source, or its direction. Position and orientation are defined by creating a LightNode and adding it to a IScene. Multiple LightNodes can share the same Light object.

Each light has a Shape - a 3D shape that defines the space that is lit by the light source. See Shape for more information.

Cloning:
Lights are cloneable. Clone()()()() creates a deep copy of the current light source - unless documented otherwise (see derived classes). Most properties including the Shape are duplicated.
