What is the difference between halogen headlights and LED headlights?
2 Answers
Halogen headlights have low production costs and stronger light penetration compared to LED headlights, while LED headlights have higher production costs, are energy-efficient, and have a longer lifespan. Below are the differences between the two: 1. Halogen lights have a brightness of only a little over 1000 lumens, whereas LED lights can reach over 3000 lumens. The lifespan of LED lights is much longer than that of halogen lights, averaging about 4 years, while halogen lights last up to 6 months at most. Halogen lights have a color temperature of only 3400K, appearing yellowish, which provides poor road illumination. In contrast, LED lights have a color temperature ranging from 4000K to 8000K, with around 5500K being the optimal color temperature—best for the human eye and producing a pure white light. Halogen lights rely on tungsten filaments to emit light, whereas LED lights use light-emitting diodes. 2. Car headlights, also known as front lights, provide illumination for safe driving at night. When the brightness of car headlights is insufficient, a headlight booster can be used. The headlight booster employs a scientific voltage-boosting method to provide a stable working voltage for the headlights. During startup, it preheats the bulb filaments for protection, allowing the headlights to emit a consistent and bright white light. This ensures the brightness remains unaffected by changes in engine speed, does not increase the vehicle's load, and is easy to install.
I've changed my car headlights several times, and the difference from halogen to LED is quite noticeable. Halogen lights are simple and cheap to install, with bulbs costing just a few dozen yuan, and they can be replaced anytime they fail. However, driving at night always feels like the light is yellowish and not bright enough, especially on highways where the field of vision isn't wide enough; they perform decently in rainy weather, offering some penetration. LED lights are initially more expensive, costing a few hundred yuan for a set, but they're much brighter, emit white light like daylight, have a wider illumination range, provide better visibility when turning, and have a longer lifespan with lower power consumption. The downside is that installation might require adjusting the direction properly, or they can glare at drivers behind. Over the long term, they save power and hassle, making them quite worthwhile. If you often drive at night, upgrading to LED lights is definitely a game-changer.
