Another idea I'm going to completely steal from Nicole's drool-worthy apartment at Sketch42 - pharmacy-style floor lamps behind the sofa.

However, I looked around and found some fairly close imitations at Lowes. Only $93 each! Unfortunately, they don't have polished nickel - but they have brushed nickel:
