we also have 2 of these ikea light fixtures - one in the downstairs hall, and one in the upstairs hall. originally i was planning on getting a third matching light to hang above the stairs, thinking that then all circulation spaces would have the same basic light fixture.

so, what do you think? both are about 1' in diameter and i think that would be a decent size. i've seen other larger lights that are ok but are much more expensive. i like how the west elm light looks with the ebay fixture, and how open it is, but i'm worried that i'm getting to have too many "statement" light fixtures, so maybe the more simple ikea light would be better? i'd love to hear what you think!
i also don't know how long of a cord you get with the west elm light, i'll have to look into that... it would hang down pretty far from the ceiling.
