Quote - Depending upon the effect you're after, I think sometimes you still might need to use a few well placed lights at low intensity to enhance the effect. Light emitting objects just don't cast enough light without making them too "hot".

 

Well, like you said, it depends on the effect. But you can get enough light  to llight the room with a light emitter. You may need to include a few more props though, such as primitives or walls, and use indirect lighting so that the light can be reflected off other surfaces.
