The McCulloch 10000K HID Bi Xenon motorcycle lighting kit (Bi Xenon means low and high beam) has approximately 2200lm output, which is more than 2x the light output of the traditional halogen light. The 10000K high intensity discharge system produces a deep blue light output approaching violet and the blue is noticeably deeper than the 8000K. Also, H.I.D. Xenon runs cooler and than your traditional halogen, therefore it will not melt your housing.
