How to make lighting effects in BGE be same as show in Camera viewport?

I want to be able to set-up a scene by moving camera and lights until I get it like I want, and then get the same view in BGE as what I see through the camera. Thanks to you all, I can do that with respect to the CAMERA view itself, but now I need to make sure that the LIGHTING also is the same in BGE as that seen through the Camera. How can I do this?
