Are there any standards for how far away the sconce should be placed from the mirror over a vanity? I know sconces should be about eye level (approx 66" from the floor) but what about side to side? How big should the sconces be? What is the ideal total wattage--and the ideal? Is there any advantage to an uplight? (I'm leaning towards shades that face down for ease of changing the bulb and cleaning--less dust.)

How do you determine the size of the mirror? Is there anything special to consider if using a pivot mirror? I'm looking at 18"w x 24" l and 18x36 size pivot mirrors. Thanks!
