Bathroom.

Bathroom lighting does more functional work than almost any other room in the home — and it's the room where poor lighting choices are most immediately obvious. A single overhead downlight above a mirror creates harsh downward shadows across the face, making grooming, makeup, and skincare difficult. The solution is layered bathroom lighting: bright overhead light for general visibility, side-mounted vanity lights at face height to eliminate shadow, and a dimmer for relaxing evening use.
