i came up with this when researching my hid, it's why i choose the 6500k. and i know not to believe everything but i sure like my double hid's on the fltr.
• The unit of the color temperature is K.
• The unit of the brightness is lumen.
• Because the sensitivity of the eye for different color is distinct, the color
temperature is too high for the eye to be sensitive, for example, the
lumen of 4300K is 3200lm, but it cuts down to 2200lm when it is
12000K.
• Do not mistake that the higher the color temperature, the brighter the
light. The color temperature is only related to the temperature of the
light color, not to the brightness.
• To an extent, the higher the color temperature, the lower the lumen,
and the penetration of the fog and raining would be worse.
• The penetration of the 3000K (golden light) is good, fitting for the fog
and raining. However, this is just for the distance, not for the bright
lighting, it is tired for the eye after a long time driving.
• We recommend the color temperature of 6000K.
• The surface temperature of the sun is 6000K, it is the same color
temperature as 6000K.
• Color temperature of the halogen lamp is 2800K
