Chromaticity and Colour Temperature

Temperature:
 

Color Temperature is a measurement in Degrees Kelvin that indicates the hue of a specific type of light source. Many people believe the misconception that colour temperature is a rating of the brightness of the bulb or HID kit. This belief is completely false. The reality of the matter is that the higher the colour temperature, the less useable light output you will obtain. A perfect example would be a black light. This light has a colour temperature of approx 12,000k and has almost no useable light or lumens output. Higher K kits such as 7000k, 7500k, etc. have been manufactured for individuals that are more concerned about the actual colour output of their lights as opposed to the actual useable light output they produce.

Chromaticity and Colour Temperature
 

Chromaticity (xy)
 

Degrees K = COLOUR ONLY Lumen= BRIGHTNESS
 

XYZ trisimulus values and the associated Yxy colour space form the foundation of the present system for numerical colour notation. The concept for the XYZ tristimulus values is based on the premise that all colours are seen as mixtures of these three primary colours. By defining the colour matching functions of a standard observer, the Commission Internationale de L'Eclairage (CIE), an international organization concerned with light and colour, provided the basis for colorimetry in 1931. The Tristimulus values XYZ are useful for specifying a colour, but the results are not easily visualized. The two-dimensional colour (x,y) diagram is taken from the Yxy colour space, in which Y is the lightness (and is identical to the tristimulus value Y) and x and y are the chromaticity coordinates calculated from the tristimulus values XYZ. The CIE x,y chromaticity diagram for this colour space is shown. In this diagram, achromatic colours are toward the center of the diagram, and the chroma or saturation increases toward the edges.
 

Colour Temperature (Tcp)
 

A black body (perfect radiant body) is an ideal object that absorbs all energy, changes its colour from red through yellow to white as its temperature increases. The absolute temperature T (K) of the black body is referred to as the colour temperature and colour by a locus (black body locus).
 

The above diagram is sometimes used to indicate the colour of a light source. Correlated colour temperature is used to apply the general idea of colour temperature to those colours that are close to, but not exactly on the blackbody locus. For instance, a light source which has a colour difference of 0.01 in the green direction (Duv) from a black body which has a colour temperature of 7,000K is indicated as having a correlated colour temperature of 7,000K + 0.01 (uv unit).

Our HID conversion kit is easy to install (plug and play) for most vehicle applications and fit directly into most existing headlights, all necessary hardware for each HID converstion kit is included.

we have all color temperature( 6000K ~ 12000K) in all bulb types.
