Pretty sure those numbers are the temperature of the bulb. 4300k (stock) produce the most light output. 6000k a little less and more blue then decreases in light output from there up.

higher you go on the kelvin scale, the less output.

I'll cut and past something for you. Color is measured in Kelvin, brightness is measured in lumens.

5000K Pure White

5000K has an approximately 3200lm output, which is more than 3x the light output of the traditional halogen light and is the color temperature with the most output. The light appears fairly white, and has light yellowish hue when reflected off the road identical to the OEM HID equipped vehicles. This color is for customers who is looking for pure performance white improving the looks of their headlight. It is idea for customers who does alot of back road or canyon driving and need the optimal visibility. This is the color temperature that give you the most light for your bucks

6000K Diamond White

6000K has an approximately 2800lm output, which is 3x the light output of the traditional halogen light and slightly less light output compared to the 5000K. Although it has a bit lesser light output, it emits pure whiter light with very slight and barely noticeable tint of blue and purple

8000K Iceberg Blue

8000K has an approximately 2550lm output, which is about 3x the light output of the traditional halogen light and slightly less light output compared to the 6000K. While it has a bit lesser light output, it emits bluer light than the 6000K

10000K Brilliant Blue

10000K has an approximately 2200lm output, which is more than 2x the light output of the traditional halogen light. 10000K produces a deep blue light output approaching violet and the blue is noticeably deeper than the 8000K.

12000K Exotic Violet/Purple

12000K has an approximately 2100lm output, which is more than 2x the light output of the traditional halogen light. This color temperature puts out a deep bluish violet light and is deeper colored than the 10000K. It is for customer who is looking for the most extreme and most exotic looking light output.

30000K Pink Violet

< 2000lm This color temperature put ot a pinkish Violet, very attractive and seperates you from the rest of the cars. Despite the high color temperature, it still put out more than 2x the light than the halogen you are currently running in your car


Now all those numbers vary slighty between brands, but the idea is the same, and FYI oem 4300k is about 3500lumens

4300k is going to offer the most light output available as far as HID color temperature goes. However, it will also have a hint of yellow in the color. 6000k will be a pure white and will decrease light output a bit with increasing blue color/decreasing light output as you go up in the spectrum.
