Which is brighter between LED and xenon headlights?
2 Answers
LED headlights are brighter compared to xenon headlights. The difference between them lies in their working principles: LED headlights directly convert electrical energy into light energy through LED chips; xenon headlights use high-intensity voltage to ignite HID bulbs to produce high-brightness illumination. LED stands for Light Emitting Diode, which is a common light-emitting device that emits light through the recombination of electrons and holes. It is made of compounds containing gallium, arsenic, phosphorus, and nitrogen. Xenon headlights refer to those filled with a mixture of inert gases, including xenon, commonly known as HID xenon lamps. They consist of a lamp head, an electronic ballast, and a wiring control box.
LED headlights are generally brighter than xenon headlights, with brightness values typically ranging from 2000-4000 lumens, while xenon headlights usually range from 1000-3000 lumens. From my own driving experience, LEDs are brighter and more stable, reaching full brightness instantly without the startup delay associated with xenon lights. They are also more energy-efficient, consuming less power and generating less heat, providing uniform nighttime illumination that reduces eye fatigue. Although xenon lights maintain stable brightness in some extreme conditions, overall they can't match the dazzling white light of LEDs, which can affect driving safety. When buying a car, it's recommended to prioritize LED headlights as they have become the mainstream technology.
