Lab which never sleeps?

Found a picture taken in our campus last Sunday. J1 is the building where my lab is. The building has 9 floors. Our room is on 8th. Maybe you can guess which one? Wonder how many hours lights are on in this room of ours..? And no, we don't keep lights on if there is nobody working (or hanging around). Hopefully last weekend was one of the last when I have stay in the lab and work all night long....thesis at the point where I should start analyzing the results of my experiments done in last 10 months.

Beautiful "Suzukakedai" campus and "J1" building.
