The question I get most often is whether bedroom lighting needs to match the rest of the house, and the answer is no, your bedroom is the one room where you're allowed to please only yourself and whoever else sleeps there.
Where it goes wrong is when people bring in anything too bright or too clever for a room meant for winding down. A fixture built for a kitchen or a hallway, something with a lot of exposed bulb or a cold white glow, reads as an interrogation in a bedroom, not a place to fall asleep. I made that mistake early on with a pair of sconces I'd rescued from an old office building, all brushed steel and glare, and put them either side of our bed thinking they'd look industrial and handsome. Margaret lasted one night before she told me she felt like she was being questioned about her whereabouts. Anything on a dimmer helps, and anything with a shade of linen or aged paper softens the light the way a lampshade is supposed to, filtering it rather than just dimming it.
What it sits well with is almost everything else in an ordinary bedroom, because a wall light mounted at the right height does a job that a bedside lamp and a nightstand can't always do in a smaller room. Reach over, flick a switch, no cord hanging down where you'll knock it over at two in the morning reaching for water. I like brass for this more than most finishes, because it takes on a warmth over the years that plastic and chrome never develop, and it sits easily next to a painted iron bed frame or a plain wooden one without arguing with either. It pairs well with a rug that's taken a few years of bare feet, with curtains that have some weight to them, with the kind of furniture that's been moved around a house more than once.
Where it's the wrong choice is in a room where you need a lot of even light for getting dressed or doing real work at a desk, that's a job for an overhead fixture or a proper desk lamp, not a soft wall light flattering you into thinking your socks match. And if you rent and can't run new wiring, don't force the issue, a plug in version mounted carefully can do almost the same job without the drilling.
The best ones have a switch built right into the fixture, so you never have to feel around in the dark for a pull cord that isn't there anymore.
