Inner Radius	Set the inner radius here or with the gizmo. Light within the inner radius will be at maximum intensity.
Outer Radius	Set the outer radius here or with the gizmo. Light intensity decreases to zero as it approaches the outer radius.
Inner Angle	Set the angle with this slider or with the gizmo. Any light within the inner angle will be at the intensity specified by inner and outer radius.
Outer Angle	Set the angle with this slider or with the gizmo. Light intensity decreases to zero as it approaches the outer angle.
