Which is brighter, xenon lights or LED headlights?
2 Answers
In car headlights, the brightness of LED lights and xenon lights is almost the same, both being 3 to 6 times brighter than halogen headlights. If we're talking about factory-installed lights, LED lights theoretically have higher durability, but the difference is not significant in actual use. Here are detailed introductions to both: 1. Xenon lights emit light by using a ballast to increase the voltage from 12v or 24v to 20,000v instantly. This high voltage breaks down the inert gas xenon, causing it to emit light. Xenon lights work by filling a quartz glass tube with xenon gas and then using a booster to instantly increase the vehicle's 12-volt power supply to 23,000 volts. Under this high voltage, xenon is ionized and produces a light source between the two electrodes. 2. LED lights emit light through LED packaging technology, which integrates chips into patches and gathers high-brightness beads in a small area to achieve light emission. LEDs are generally used in car taillights or front headlights and, to some extent, have a decorative function.
I usually drive more at night, and the actual test shows that LED brightness is indeed more intense. No need to remember the lumen value—just imagine an LED cutting through the road like a lightsaber in the dark, while xenon lights slowly diffuse a warm yellow glow. I remember last time driving on a mountain road, the reflection from road signs under LED lighting was even dazzling, but in heavy fog, the 4300K color temperature of xenon lights felt more stable. However, newer LED models now come with lenses for focused light. My car hasn’t needed a bulb change in three years since the upgrade, whereas xenon lights require regular replacement of ballasts—the difference in hassle-free maintenance is clear.
