What is Color Rendering Index (CRI)?

Color Rendering index (CRI) is a rating scale to assign the effectiveness of a light source in rendering colors, compared with natural daylight.  A CRI of 100 is equal to natural daylight referring to the highest ability of color rendering which is by the sun itself.  On the contrary, a low CRI of 50 or less means that the light source does not render colors very well.  An acceptable CRI in fluorescent lighting is 80 to 95, which equates to an excellent color rendering ability. 

Where is CRI Important in Industry?

Knowing the CRI of your lighting has great benefits and will provide competitive advantages in certain industrial applications.  For example, in the jewelry store you want your lighting to reflect the full spectrum of lighting when exposed to diamonds and jewels, showcasing your items and making them more appealing and desirable. 

A high CRI index used in clothing displays makes a big difference in the appearance of clothing, casting an appealing glow in the right displays to reveal vibrant color schemes.  Food displays in restaurants, showcasing primed aged meats or delectable desserts can make the difference in a consumer’s decision to appease their appetite.  Whatever your lighting application, do not underestimate the power of pleasing, high quality lighting with a high color rendering index.

LCD Lighting, a valued partner company to The LightSources Group, has developed proprietary color rendering index technology with more rare-earth tri-phosphors revealing natural true colors.  With advanced technology, LightSources and LCD Lighting can develop custom colors for specific requirements in various applications.
