Need a tip on lighting a scene.

It's a typical living room, the camera will be pointed at three girls huddled on the couch watching a scary movie. The only light in the room will be coming from the TV. Is that a Scene Only thing in Render settings?

Unless you want light artefacts from 'outside' such as reflection of moon, etc., I'd stick with just Scene Only type lighting.

Click on the television screen, go to the surface tab, open the emission tab and load the tv screen diffuse map into it, change the lumens to produce light enough to shine on the girls.
