The VRayLightSphere is a VRay Light object in the shape of a sphere. It is a good general-purpose V-Ray light for illuminating scenes to simulate real-world point light sources such as lamp bulbs.
The sphere can be scaled to any size and emits light outward in all directions.

Enabled – Enables the VRayLightSphere.
Color Mode – Chooses the mode in which the color of the light will be specified.
Light Color – When Color Mode is set to Color, this parameter controls the color of the light. When using photometric units, this color is normalized so that only the color hue is used, whereas the light intensity is determined by the Intensity multiplier parameter.
Temperature – When Color Mode is set to Temperature, this parameter controls the color of the light in degrees Kelvin.
Intensity multiplier – Multiplier for the light color; this is also the light intensity in the units chosen by the intensity Units parameter.
Units – Dropdown to select light units. Using correct units is essential when you are using the VRayPhysicalCamera. The light will automatically take the scene units scale into consideration to produce the correct result for the scale you are working with.
default – The color and multiplier directly determine the visible color of the light without any conversion. The light surface will appear with the given color in the final image when seen directly by the camera (assuming there is no color mapping involved). Lumens – Total emitted visible light power measured in lumens. When this setting is used, the intensity of the light will not depend on its size. A typical 100W electric bulb emits about 1500 lumens of light. lm/m/m/sr – Visible light surface power measured in lumens per square meter per steradian. When this setting is used, the intensity of the light depends on its size. Watts – Total emitted visible light power measured in watts. When using this setting, the intensity of the light does not depend on its size. Keep in mind that this is not the same as the electric power consumed by a light bulb for example. A typical 100W light bulb only emits between 2 and 3 watts as visible light. w/m/m/sr – Visible light surface power measured in watts per square meter per steradian. When this setting is used, the intensity of the light depends on its size.
