For mirror and vanity lighting, use CRI 90+ (ideally 95) LED strip at 4000K around the mirror edges and a soft backlight behind frosted acrylic. A slim 3-8mm COB strip gives dot-free, shadow-free face lighting that flatters and works — pair it with a dimmer for day-to-night scenes.
Why Mirror Lighting Needs Quality Light
Mirrors reflect the worst light problems: shadows on your face, harsh dots, and wrong color casts that make makeup and grooming unreliable. Continuous, high-CRI, evenly spread light is the difference between a vanity that flatters and one that fights you.
Front vs Back Lighting
| Style | Effect | Best For |
|---|---|---|
| Back-lit (behind mirror/frame) | Soft halo, no glare | Bathroom ambiance, hotels |
| Side strips (front) | Bright task light on the face | Makeup vanities, salons |
| Full frame (top + sides) | Even all-around light | Premium makeup mirrors |
Color Temperature and CRI for Vanity
Daylight 4000-5000K with CRI 95 is the salon standard — it mimics daylight so makeup looks the same outdoors. A CCT-tunable strip (2700-6500K) adds flexibility: cool for makeup in the morning, warm 2700K for relaxing at night.

Installation: Behind Frosted Acrylic
- Mount the strip behind a 4-6mm frosted acrylic panel for perfectly even diffusion.
- Use a 3mm super-slim COB strip for shallow frames.
- Keep the strip 2-3cm from the mirror edge to avoid bright lines on the glass.
- Run the driver in a cool, dry spot; use 24V for runs over 3m.

Frequently Asked Questions
Front or back-lit mirror?
Back-lit (behind the mirror or frame) gives soft, glare-free ambient light; front-lit strips on the sides give brighter task light for makeup. Many bathrooms use both: back glow + 4000K side strips.
What CRI do I need for a makeup mirror?
CRI 90+ minimum, ideally CRI 95 — accurate color for makeup application. Below CRI 90, foundation and lipstick colors look wrong.
How much strip do I need around a mirror?
For a 60x80cm mirror, 3-4m of strip (two sides + top) at 9.6W/m gives comfortable vanity lighting of ~500 lux.
Can LED strip be dimmed on a mirror?
Yes — use a trailing-edge dimmer or a touch dimmer built into the mirror kit for stepless brightness control.
