Vray light question

Thanks…that explains that but I’m with Richard…why? Also, what about the light values…please see attached. This is an interior scene I worked on and if you check the power values of the lights in the soffit, they technically way out of whack but visually it looks correct. This has happened in all of my interior scenes. For some reason, I can never use the manufactured lighting specs because it does not produce enough light. I remember in Lightscape, I was able to put in the manufacture specs and it would produce a physically correct lighting scenario. So…what am I not doing correctly in Vray?

Thanks

Scott
