The radius of the light emitting shape.

Remarks
By default the radius is zero and the emitting shape is just a point. If the radius is set to a larger value, the shape becomes a sphere or even a tube, if Length is also set.
A non-zero radius yields more realistic lighting for light bulbs and other objects that have a glowing surface. However, for performance reasons the computation is only an approximation of an area light. If such a light source comes too close to geometry or even intersects with it, the resulting lighting won't be physically correct.
A InvalidParam error occurs if the value is negative, NaN or infinite.
