I hope not ;-) Still, I am not really sure whether I am doing right... 
Does anyone know whether the lamp,tab-lookup done by ies2rad also 
accounts for the luminous efficacy of a source? This would be required 
to get correct radiance values for rgb from the candela-distribution of 
a source. I would e.g. assume an efficacy of 100lm/W for my source, and 
if ies2rad would use 179 instead, the radiance values in my simulation 
would be by far too low...

Cheers, Lars.
