NOTE When the LIGHTINGUNITS system variable is set to 1 or 2, the Attenuation
option has no affect on the creation of the light. It is only maintained for scripting

Name
Specifies the name of the light. You can use uppercase and lowercase letters,
numbers, spaces, hyphens (-), and underscores (_) in the name.
Intensity/Intensity Factor
Sets the intensity or brightness of the light. The range is 0.00 to the maximum
value that is supported by your system.
Hotspot
Specifies the angle that defines the brightest cone of light, which is known to
lighting designers as the beam angle. This value can range from 0 to 160
degrees or the equivalent values based on AUNITS.
Falloff
Specifies the angle that defines the full cone of light, which is also known as
the field angle. This value can range from 0 to 160 degrees. The default is 50
