Colour Chart

 

The 'K' denotes Kelvin, which is the primary unit of temperature measurement in physical sciences, in this instance the 'colour temperature'.

4300k - This is usually the factory fitted xenon bulb specification and is described as a warm white colour, most household fluorescent are accepted to be at the 4300k - 4500k mark.

6000k  - This is considered to be the most optimum colour for road usage and aesthetics, this colour omits a brilliant white light (ice white) and is best described as 'noon sunlight'.

8000k - This shade gives more blue overtones, it omits a more blue light which can be described as shaded skylight. This colour is less effective in terms of visibility than both 4300k and 6000k.

10000k - Like the 8000k but a darker shade of blue. This shade gives you less usable light.
