Thanks for the comprehensive list Larry. 

The one thing I'll say about IES lighing profiles is that some have very little apparent effect on the rendered results and some are really obvious. This is also a function of distance from light to object receiving the light. 

Scaled scenes are a must for IES to work well. For example, the profile for an R20 spotlight will have obvious patterns when shining on something 8 feet away in a scaled scene or is right up against a wall. However, if you shine that profile on an object 100 feet away, the patterns will be lost.
