Vray light units - watts vs lumens

Hi, I am in a bit of misery here. Most of the articles in this topic are mentioning that 1600 lumens are more or less equal of a 100w lightbulb. I know the difference between the two units by the way. My problem comes from vray. As you setup your light with watts or lumens vray will make a conversion if you switch light units. The numbers you can see on the attached image made me create this post. Can anyone tell me what the hell is happening? Cheers, 142688
