The 3000K McCulloch Bi Xenon HID bulbs (Bi Xenon means low and high beam) have an approximately 3200lm output, which is more than 3x the light output of the traditional halogen light. 3000K High Intensity Discharge emits GOLDEN YELLOW color and offers superior penetration power during adverse weather especially in dense fog. The applications of the 3000K high intensity discharge kit / lights aim more towards secondary lighting apparatus such as high beam and fog lights. The 3000K H.I.D. capsule is actually a 5000K capsule specially coated with a film that filters out all the wave length except the range of wave length which emits yellow.
