It depends on the mirror model and the type of dimmer.
Most LED mirrors have built-in dimming controls on the mirror face itself,
so a wall dimmer is usually not required — and in some cases,
an incompatible wall dimmer can cause flickering or damage the LED driver.

If you want wall-switch dimming:
– Check that your mirror’s LED driver is rated as “dimmer compatible”
– Use a leading-edge (TRIAC) or trailing-edge dimmer rated for LED loads
– Avoid cheap universal dimmers — they’re a common cause of LED flicker

STANHOM mirrors with built-in dimming use touch controls on the mirror
surface for brightness adjustment — no wall dimmer needed.
