1 | location specifies the 3-D coordinate of the light. |
2 | radius defines the maximum reach of light. A shape that is far away from the light will not show the effect of this light. |
3 | intensity controls the brightness of the light source. It can have value between 0 and 1. To turn off the light, set its intensity to zero. |
4 | ambientIntensity field controls the effect of the light source has on the ambient-light level for shapes within the light's radius. |
