The other thing you forgot to mention that's really great about these fixtures is that they fit into standardized sockets installed in the ceiling. Every apartment has the same ceiling sockets, so you can just buy one of these UFO-looking lights and install it on your ceiling in 10 seconds.

Another interesting point for American readers is that these light fixtures belong to you. When you move into an apartment, there are no light fixtures inside, just those empty sockets I mentioned. (Or, if you're lucky, they'll have a cheap adapter and a regular edison-socket bulb, so you can see at night until you buy a real light fixture.) Just like the refrigerator, you have to bring your own. So you might as well get a nice one, because when you move, you can bring it with you.
