Lol, I totally agree 
The lights being turned on during daylight like that is odd, but it’s how they do on interior archviz photography many times… It’s like the original scene as you can see here (page 6): http://www.evermotion.org/modelshop/show_product/archinteriors-vol-29/9520/0/0/
The problem is that I didn’t give too much attention to the light intensities, I’ve just applied the same bright material on every single lamp :D. Ambient light is also brighter in my scene than in the original one. I’ll work on that later.
