A flush mount lighting fixture can incorporate aspects that provide reconfigurability and convenience. Selector switches can provide a wide selection of illumination levels and color temperatures. The switches may be inaccessible while the fixture is installed to thereby prevent unwanted adjustment. A magnetically attached faceplate is easy to install, replace, adjust, and change for other faceplates. A top diffuser may be interchangeable with a wall wash insert. The top diffuser can produce a lighting pattern that is circularly symmetric with a fixture axis of the fixture. The wall wash insert produces a lighting pattern that is asymmetrical and may be offset from the fixture axis of the fixture.
