What is the difference between LED headlights and halogen headlights?

[DeAdelyn]

The differences between LED and halogen headlights are: 1. Different principles: LED headlights emit light through diodes; halogen lamps use tungsten filaments to emit light. 2. Different energy consumption: LED lights consume less energy; halogen lamps consume more energy. 3. Different brightness: LED lights are brighter; halogen lamps are dimmer. 4. Different color temperatures: LED lights offer multiple color temperature options; halogen lamps have only one color temperature. More details about LED and halogen headlights: 1. LED headlights, also known as automotive headlamps, are lighting fixtures used for illuminating the road ahead during nighttime driving, symmetrically installed on both sides of the front of the vehicle. 2. Halogen headlights are a new generation of incandescent lamps, filled with halogen elements such as bromine or iodine or their compounds. To improve the luminous efficiency of incandescent lamps, the temperature of the tungsten filament must be increased, but this leads to the sublimation of tungsten, which condenses on the glass bulb, causing it to blacken.
