Specifies the angle from center of the spot light where light begins to fall off. The value must be greater than or equal to 0 and less than outerConeAngle.

Specifies the local direction of the spot light. Local direction is affected by parent transform rotations.

Specifies the cut off angle of the spot light. Objects outside this angle receives no light from the SpotLight. The value must be greater than innerConeAngle and less than or equal to 180.

Specifies the destance at which the light intensity may be considered to have reached zero and has no effect. A range of 0 (default) indicates infinite range
