Hello to give you the most accurate reflection too much light could be an issue. The Mirror is designed to provide the best functional light possible, I do not think you would need the sconces for that purpose. Now as far as lighting the room, then depending on the layout and size perhaps adding sconces would be a good addition. Also if you do want to add sconces, we suggest keeping the mirror and the sconeces on two separate electric lines. I hope this helped. thank you.
