What is colour temperature and which CT (color temperature) is best for driving?
Many people believe that the higher the colour temperature the brighter the lamp. This is totally wrong. The colour temperature is purely a scale to measure the colour of the light output. It is a reference purely for colour and could equally be called White, Green or Blue. The reality is the higher up the scale the lamps are the less bright they become. 5200K lamps are approx 10% brighter (measured in Lumens, not degrees K) than the 7000K. If you want lighting performance the 5200K HID lamps are the best. In our opinion 6000K has the best and most attractive light output.
