Screenshot and Launch doesnt look like in the viewport

Hi,
After I aranged my scene, in the viewport and in play mode it looks how it should, but my lighting looks totaly different when i take a screenshot or when i launch it.
I would like to show my scene to a friend without scanning my screen, please help.

Is the lighting built? Can you take a screengrab to let us see what it is you are experiencing?

Hi,
