•While halogen bulbs does not have the lifespan or light intensity of xenon versions, they are still much more common, and it is easier and less expensive to replace halogen bulbs. There is also some controversy as to how much better the xenon bulb's light is, if at all, and different bulbs will have different effects. While halogen burns hot, around 3,200 degrees Kelvin, xenon bulbs tend to burn even hotter, up to 12,000 degrees Kelvin, and can pose more of a heat risk.
