What is the lifespan of xenon bulbs?

[McRuth]

Xenon bulbs typically have a lifespan of around 3000 hours. The advantages and disadvantages of xenon bulbs are as follows: Advantages of xenon bulbs: Xenon bulbs are three times brighter than halogen bulbs, significantly improving visibility during night driving and in foggy conditions. The luminous flux emitted by xenon bulbs is more than twice that of halogen bulbs, and the efficiency of converting electrical energy into light energy is also over 70% higher than halogen bulbs. Therefore, xenon bulbs have a higher energy density and illumination intensity. The increased brightness of car headlights effectively expands the visual range in front of the vehicle, creating safer driving conditions. Disadvantages of xenon bulbs: Xenon headlights have weaker penetration than halogen headlights in rainy and foggy weather, so it's best to retain two halogen headlights for use in heavy fog conditions along with fog lights. Xenon bulbs also have poor focus and exhibit a delay effect.
