Which is brighter, xenon headlights or halogen headlights?

Xenon headlights are brighter than halogen headlights. The luminous arc of xenon lamps is the same length and diameter as the tungsten filament of halogen lamps, but the brightness of xenon lamps is three times that of halogen lamps. Xenon lamps can produce 3200 lumens, while halogen lamps only produce 1000 lumens. However, in low-visibility weather such as rain or fog, halogen lamps have better penetration. Below is a detailed introduction to both: 1. Xenon lamps (HID), also known as high-intensity discharge lamps, work by increasing the 12V voltage to an ultra-high voltage of 23000V, which excites the xenon gas filled in the quartz tube to emit light. The voltage is then converted to about 85V to stably and continuously supply the xenon bulb with power. Additionally, HID lamps avoid the issue of halogen lamps, which tend to oxidize and dim over time. Xenon lamps provide a wide and long illumination distance. 2. Halogen lamps are essentially a special type of incandescent lamp. Their principle is based on the fact that when current passes through a resistor, it generates heat. When the temperature is high enough, it emits blackbody radiation in the visible light spectrum.
To be honest, I've driven many cars, and after modification, xenon headlights far surpass halogen lights in brightness. The light is whiter, brighter, and illuminates the road more clearly, especially noticeable when driving on mountain roads at night. Technically, xenon lights use a high-pressure gas discharge principle, doubling the brightness, but they require an additional ballast device, making them more expensive. Halogen lights are simpler and cheaper, with a yellowish light and noticeably poorer illumination, often feeling like outdated bulbs. In the long run, xenon lights are more durable and energy-efficient. Although pricier, they offer greater nighttime safety. I recommend trying an upgrade to avoid driving hazards.
