SOME CONCEPTS
CRI VALUE
The CRI value of a light source is a value from 0 to 100 that indicates how accurately the colors are
rendered by the light source compared to how the colors look with sunlight. The higher this value, the
more accurate and vivid the projected image will look. In concrete terms, this means that when you
send a certain color to the LED strip, this color will be displayed more accurately by the light source.
This color rendering index is independent of the light color of the light source. For example, cold-
colored and warm-colored light sources can have the same CRI. It is recommended to buy light
sources with a CRI of min. 80. On the right a simulation ...
COLOR TEMPERATURE
The color temperature is a measure of how warm or cold the white color of the lamp is. This is
expressed in degrees Kelvin (K). When a lamp has a high Kelvin value, the light emitted is colder. This
can be clarified by means of a light bulb. An incandescent lamp has a significantly warmer color than
LED headlights of a car. Depending on the application, different color temperatures are used. For
example, warm light (lower K) creates more cozy atmospheres, while colder light (higher K) increases
concentration. LED strips exist in all color temperatures from cold to warm white and in between.

COLOR MIXING
RGB LED strips are capable of forming many colors. Yet they run into limitations. This is solved by
adding other light chips according to the desired result.
