Color 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 25,000k and has almost no useable light or lumens output. Higher K kits such as 12,000k, 14000k, 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.

What is Lumen (lm) ?  
The international unit (SI) of luminous flux (quantity of lights). For example, a dinner candle produces about 12 lumens and a standard 60-watt incandescent bulb produces 830 lumens.
