Light Name
Specifies the name of the light. The name must be no more than eight
characters long.
Intensity
Sets the intensity or brightness of the light. Entering 0 turns off a light.
The maximum point light intensity depends on the attenuation setting and
the extents of the drawing. If attenuation is none, maximum intensity is 1.
If attenuation is inverse linear, maximum intensity is the value of twice the
extents distance: the distance from the minimum lower-left coordinate to the
maximum upper-right coordinate. The default value for inverse linear is half
the maximum intensity.
If attenuation is inverse square, maximum intensity is twice the square of the
extents distance.
Position
Modifies or displays the X,Y,Z coordinate location of the light and its target.
Inverse Linear
Sets attenuation to be the inverse of the linear distance from the point light.
For example, at a distance of 2 units from a point light, light is half as strong
as at the point light; at a distance of 4 units, light is one quarter as strong.
The default value for inverse linear is half the maximum intensity.
