Please note: most customers have a common misconception that the higher the K (Kelvin temperature) the brighter it gets, but in fact, it is the opposite. The K rating is inversely proportional to the light output, therefore the lower the K the brighter the light output. Also Xenon runs cooler and than your traditional halogen, therefore it will not melt your housing.
