CRI - The Quality of Light!
 


The concept of color rendition (CRI) has become a standard in the lighting industry for evaluating the quality of light being produced by a fluorescent lamp. Although the actual measurement of color rendition is a highly complicated process, the basic concept is that the higher the color rendering index (CRI) rating of the lamp towards the theoretical index of 100, the better the quality of the light being produced by the lamp.

There are two basic methods that can be used to accomplish a high color-rendering index in fluorescent lamps. One method is accomplished by using a full continuous spectrum through the blending of various phosphors. The other is by using a mixture of light in the three "primary" color spectrum areas of blue (450 nm), green (540 nm) and red (611 nm).  The proper combination of light output in these three areas can create a high degree of color rendering at a specific color temperature.

 

  phosphor blend offers a full spectrum of light that simulates the spectrum of mid day sunlight. It has a color temperature of 5600 Kelvin with a CRI index of 93.
