In 2.0.11, there isn't light when you're close to the lighting body, probably so you can see it's texture and it doesn't just become one big light, which I think is a good thing.
At large distances, like over many AU's, I think the lighting is too weak though. If the bodies are drawn at their actual size, the Sun disappears in less than 1000 AU's, and you can't see VY Canis Majoris one light year away from it, and Eta Carinae fades away less than 5 ly away. It would be awesome if the light could make up for that.
