Sorry, I have no experience with MVB, and that is because I have read numerous pages on where its actually bad for humans to be in contact with its rays for extended periods of time.. whether this information is viable I have no idea, but this was a research topic and supposedly was scientific research, but who knows, alot of people say different things. I know MVB's last longer and give out a great amount of UVB in longer distances, but that I cant be sure of either, its heresay. I am sticking to my 10.0
