1. Color rendering property
In principle, artificial light should be the same as natural light, so that the human eye can correctly distinguish the color of things, of course, this should be determined according to the position and purpose of lighting.
The degree to which the light source presents the color of the object is called chromogenic. This is often called the "rendering index" (Ra). Color rendering refers to the relationship between the true color of an object (its own color) and the color displayed under a standard light source. Ra value is determined by comparing the 8 test colors defined in DIN6169 with the standard light source and the tested light source. The smaller the color difference is, the better the color development of the measured source color is.
A light source with an Ra of 100 means that things appear the same color under its light as they would under a standard light source.
2. Color Temperature
When the color of the light emitted by the light source is the same as the color of the radiation of the black body at a certain temperature, the temperature of the black body is called the color temperature of the light source, expressed in terms of the absolute temperature K (Kelvin, kelvin = Degrees Celsius + 273.15).
