No. 2: Wall Sconces
Lamps are things you can change out on a whim. Wall mounted sconces are harder, and more expensive, to install. Once installed, you can get them changed out relatively easily. Make the initial investment to get sconces installed. Choose your wall sconces and their location wisely and just go for it. Put them on dimmers. And put them up asap!
The light quality from sconces is great. I am a fan of interior lighting not coming from above. Of course wall washers and spotlights have their place- but the lighting that makes one feel cozy and look beautiful comes from indirect sources- wall mounted fixtures and lamps. Also, overhead lighting really clutters up the ceiling plane and can make a residential space look commercial. Other than the kitchen and select areas in the bathroom, forgo the overhead recessed lighting.
Great places for wall sconces include the foyer, flanking art or a large mirror in any room, flanking or installed on a media build-out or built-in, placed high on the walls in hallways, flanking the bed as task lights for reading, flanking the vanity mirror in the bathroom, and picture lights placed above your art. A guideline for the size of a picture light is half the size of the art, placed at the center line of the piece, above the frame. If lighting a really large piece of art, recessed fixtures are the solution. If lighting a really, really important piece or collection of art that is museum quality- I, as a designer, would consult a specialty lighting designer for proper fixtures so as not to damage the art overtime (I recommend you do this if this sounds like your situation).
Start with one set of swing arm sconces in the bedroom and one set of sconces in a main living area. Add them to hallways and other rooms as you can. Have art lights installed over your most important and favorite art, then add them to each piece as you acquire and grow your collection.
