The color rendering index (CRI) is an optical indicator proposed by the International Commission on Illumination (CIE) to measure the accuracy with which a light source reproduces the colors of objects. It is expressed as a percentage; the higher the value, the more accurate the color reproduction of the light source.
Key Eye-Friendly Parameters for LED Vanity Light Fixtures: 1. Luminous Flux (Brightness) 2. Color Temperature (Cool or Warm) 3. Color Rendering Index (CRI or Ra value) 4. Blue Light Hazard and Wavelength Control 5. Flicker-Free Design 6. Beam Uniformity and Anti-Glare Design 7. Power and Energy Efficiency 8. Adjustable Light Modes and Memory Function 9. Light Decay and Lifespan
LED vanity light fixtures typically feature a frosted cover or light diffuser design, providing a soft and even coverage of the face, avoiding glare and partial shadows. Traditional bulbs, on the other hand, produce concentrated light with noticeable spotlights.
