| CCS has developed a natural-light LED with the light quality of the
fresh morning sun. This LED is used as the light source in the Diamond
Light. Natural light contains many colors as evidenced by the seven
colors of a rainbow. Lighting designers at CCS modeled the natural-light
LED after sunlight for its rich spectral content, so that you can enjoy the
brilliance of diamonds, especially dispersion.

| CCS's natural-light LED achieves superior color reproduction and has high color rendering indices for all of the 14 colors used to evaluate light sources. *A color rendering index is used to evaluate the ability to render each of 14 colors against a standard value of 100. *The average color rendering index, Ra, is the average of the values for R1 to R8. The special color rendering index, Ri, is an evaluation index for each of the 14 test colors (test color number, i = 1 to 14). |
   |
| The average color rendering index, Ra, of the natural-light LED is 98 out of 100, the highest in the industry. It faithfully reproduces the true colors of diamonds, as seen under natural sunlight. |
 |
 |
Sunlight contains a wide range of light from ultraviolet to infrared. |
 |
 |
The spectral distribution is modeled after natural sunlight in order to enhance the color and brilliance of diamonds. It also complements natural skin tones. |
 |
 |
The blue component is too strong, making the dispersion unbalanced. |
 |
 |
The light is diffused, so dispersion and scintillation do not occur. |
 |
 |
The yellow and red components are too strong, making a diamond appear yellow. |
The photographs were produced to simulate the effects of various light sources.
