Just to make sure I do understand it right: you did *not* actually use 
IES files, you 'just' did model a realistic spotlight with a refracting 
mirror?

If my memory does serve me well there was (maybe a few years ago) a post 
by someone who did in fact use IES files within POV-Ray. But while I'm 
thinking about it, I have no idea how this could be achieved.
