What Are LED Backlit Mirrors?
A backlit mirror is a mirror with a hidden LED strip placed behind or around it.
The light bounces off the wall, creating a soft halo glow without visible bulbs.
This creates:
- Even, diffused light
- A floating-mirror effect
- Zero shadows on the face
- A sleek, minimal design
These lights are commonly used in bathrooms, hallways, vanity tables, walk-in closets, and hotel-style interiors.
