Best viewmode to work in when doing lighting?

I am trying to match the lighting thats in this concept, so I figured its best to work in lighting only when doing lighting so I have it going pretty good as far as contrast but then I go to Lit Mode and its way to dark. Is this not the best mode to work in? Im afraid to work in Lit mode when doing lighting because I might make it to overpowering.

Any suggestions.

Also why am I getting color information on my models in lighting only mode?
