It's a theoretical question trying to get at how their algorithm actually works. My guess is going to be that they all match at one natural Poser unit from the lights. Another way to think about the question is: If I have a Poser 7 light set and want to use it in Poser 8 with linear/quadratic lights instead, how should their intensities be chaged to keep the light on the primary subject the same? It's going to depend on the distances from the subject to each light.

Whichway
