What are the differences between halogen, xenon, and LED headlights?

Below are the specific differences among the three types of automotive headlights: 1. Light intensity: The light intensity of the three types of automotive headlights, ranked from strongest to weakest, is as follows: LED lights are the strongest, with a light output of 6200 lumens; followed by xenon lights, which are moderate, with a light output of 4500 lumens; halogen lights are the weakest, with a maximum light output of 1200 lumens. 2. Durability: LED lights have a lifespan of up to 100,000 hours; xenon lights last more than 30,000 hours; halogen lights have an average lifespan of 500 hours. This shows that LED lights also have the longest lifespan.
Halogen, xenon, and LED lights are mainstream automotive lighting types, with core differences in brightness, energy consumption, and lifespan. I've technically analyzed these lights: Halogen lights are the cheapest, emitting a yellowish, non-glaring light, but their brightness is average, and energy consumption is absurdly high—making night driving visibility poor. Xenon lights significantly boost brightness, being two to three times brighter than halogen, yet consume 30% less energy. The downside is their slow startup, taking one to two seconds to reach full brightness, which might affect reaction time in rainy conditions. LED lights are the most advanced, with the lowest energy consumption, near-instant illumination, and a lifespan of tens of thousands of hours—lasting years per replacement without harming the battery. Their high brightness ensures clear road visibility, though they come at a higher price. Overall, xenon and LED lights offer better safety performance, reducing accident risks, but modifications must ensure voltage compatibility to avoid blowing fuses. The choice depends on budget and needs—halogen lights save costs for older cars, while LED lights are more cost-effective long-term for new vehicles.
I previously tried modifying the lights on my car and found that halogen lights, while traditional, are outdated. Their dim, yellowish glow resembles candlelight, making highway driving often strenuous. After upgrading to xenon lights, the illumination was much brighter with a dazzling white light, making nighttime driving much easier and saving a lot on fuel costs due to lower energy consumption. The downside is the need for additional ballasts; otherwise, there's a risk of slow startup and potential hazards. LED lights, however, are my favorite—they provide uniform brightness without glare, respond as fast as lightning, offer clear visibility during turns, consume very little energy to save the battery, and have a long lifespan lasting several years without replacement. Although more expensive, they are worth the investment. In practical experience, halogen lights tend to overheat and burn out bulbs, xenon lights are troublesome to maintain, while LED lights are the most reliable. Considering weather conditions, halogen lights perform better in rain and fog due to their superior light penetration, whereas LED lights might cause glare due to their intense brightness. In conclusion, when modifying car lights, it's essential to weigh safety and cost, not just follow trends.
