■ Inverse Squared. Sets attenuation to be the inverse of the square of the
distance from the light. For example, at a distance of 2 units, light is one
quarter as strong as at the spotlight; at a distance of 4 units, light is one
sixteenth as strong.
Use Limits Specifies whether to use limits or not.
Attenuation Start Limit Specifies the point where light starts as an offset
from the center of the light. The default is 0.
Attenuation End Limit Specifies the point where light ends as an offset from
the center of the light. No light is cast beyond this point. Setting an end limit
increases performance where the effect of lighting is so minimal that the
calculations are wasted processing time.
Color/Filter Color

Index Specifies an ACI (AutoCAD Color Index) color.
