I got the 3-light and 2-light size of this lamp. The 2-light is quite small, perfect for my  narrow hallway. The 3-light is good for a 9 foot square room, but if your room is any larger I'd go bigger (I think it comes in a 4 or 5-light size). These cast way more light than our old flush mounts - we had to go down to 40 watt bulbs, even in the small 2-light. You do need to assemble the light before mounting to ensure things are adjusted correctly. But then, ignore the instructions telling you to mount it fully assembled as that's really difficult. Take off the diffuser so you can hold it while mounting.
