The specifications that matter
Face light is the room's headline task: grooming happens at the mirror, and light must reach faces from the front, sconces flanking the glass near face height, or vertical lighted elements doing the same job. Overhead-only lighting rakes shadows down brows and chins; the fix is geometry, not wattage, and it is drawn at rough wiring or improvised forever after.
Color quality and temperature are honest-mirror questions: high color-rendering sources keep skin tones truthful for grooming and health checks, and the chosen temperature should flatter consistently across every fixture rather than mixing warm and cool by accident. Whatever the temperature, buy it in quality, cheap sources with poor rendering make every palette and every face worse.
The safety layer completes the system: wet and damp location ratings matched to where each fixture lives, shower zones have rules for good reasons; controls reachable at the door and, in aging households, without crossing a dark room; and the night path, door to toilet, lit at a level that guides without waking. Ventilation-light combos and lighted mirrors join the system where they serve it, specified by the same layers rather than as gadgets.
