What is the difference between halogen headlights and LED headlights?
2 Answers
The differences between LED and halogen headlights lie in temperature, color temperature, brightness, and lifespan. The specific differences between LED and halogen headlights are as follows: 1. LED headlights are cold light sources with a color temperature of 6000K, emitting pure white light, and have a lifespan of 50,000 hours. 2. Halogen headlights are hot light sources with a color temperature of 3200K, emitting warm light, and are prone to light decay or damage after 500 hours of use. How to choose between LED and halogen headlights: Choosing LED headlights is a better option as they offer many advantages. They are not affected by temperature when in operation. The light emitted is a pure white color with good reflective properties, strong penetration at night, and a longer illumination distance, providing better visibility.
Having driven for over a decade, the difference between halogen and LED lights is night and day. Halogen lights are those yellowish bulbs commonly found in older cars—replacing one costs just 20-30 yuan, but they burn out so easily that I always carry spares on long trips. LEDs, on the other hand, are game-changers. The ones installed in my new car haven’t had a single issue in three years, with daylight-like white beams that make road signs glow. But when switching to LEDs, heat dissipation is critical—last time I helped Old Zhang retrofit his lights, he cheaped out on a no-name brand and ended up warping the housing. For frequent night driving, LED brightness can be a lifesaver, but they must be paired with projectors; otherwise, the scattered glare will blind oncoming traffic.
