Which is brighter, xenon headlights or LED headlights?

Compared to xenon headlights, LED headlights have stronger light output. LED headlights generate light directly through multiple diodes, so there is no delay in the light emission. Moreover, the light emitted by LED headlights is intense. While this allows the driver to observe road conditions very clearly at night, it can also cause visual interference to other vehicles. Here are the characteristics of LED headlights: 1. Energy-saving: LED car lights are cold light sources, generally consuming less power and saving over 70% more energy than traditional light sources. 2. Eco-friendly: The spectrum contains no ultraviolet or infrared rays, producing neither heat nor radiation, with minimal glare. Additionally, the waste is recyclable, pollution-free, and contains no mercury, making them safe to touch and a typical example of green lighting LED sources. 3. Long lifespan: There are no loose parts inside the lamp body, and it is free from issues like filament burnout, thermal deposition, or light decay. With appropriate current and voltage, the service life can reach 60,000 to 100,000 hours, which is over 10 times longer than traditional light sources.
I’ve always felt that LED headlights are brighter, especially in newer models. Xenon headlights are also quite bright, but they take a few seconds to warm up to full brightness—kind of like warming up before driving—whereas LEDs reach full brightness instantly, which is super convenient. The light from LEDs is more focused, bright white, and clear, providing a wider field of vision at night, which greatly enhances safety. Additionally, LEDs are much more energy-efficient, consuming less power and generating less heat, which is particularly crucial in city traffic or long-distance driving. Since switching to a car with LEDs, I’ve felt like the lights illuminate the road ahead directly, almost like a mini sun. Xenon headlights do fall short in terms of brightness and response speed.
