Is you want more exhaust than intake. That is if your intake isnt just cancelling your exhaust out. Try flipping the fan around that is blowing, so it will be sucking hot air from the light and do the same for the fan bringing air into the room so it is not exhausting. See if that helps. Of course you can always just try it and if im wrong switch it around.
