Ceiling light problem

[Tutmozis]

Hello.

I made my first room for learning (recreated original bedroom).
And I want to see which renderer is better, so I made a 11 sec movie at best default settings.

See the video:

The first problem was the curtain, but I fixed it, as I stated at my previous topic.
The second problem is, that ceiling look too dark, even if its pure white. Everything in the room look ok regarding light, but ceiling is not good (it's a separated box by the way). What's the problem, and can I made a ceiling which radiate light in .mtl for example ?
