Idk, but others will.... do you have photos to post? depth / detail of the mirror... Sconce- can it be more 'spare' with minimal lines?

From houzz article [story]: "The American Lighting Association’s general rule is to mount them 65 to 70 inches from the floor, at about eye level. This allows light to fully illuminate your entire face without casting shadows. Ideally, the fixtures should be placed about 28 to 30 inches apart, but achieving this depends on the size of the room and configuration of the design.... Installing dimmers is worth the effort and cost; bright task lighting that’s optimal in the day can be softened in the evening."
