What are the differences between halogen headlights and LED headlights?

[LeAmara]

The differences between halogen headlights and LED headlights are: 1. Different principles: Halogen headlights work by the tungsten filament inside the bulb glowing when electrified and heated; LED headlights utilize a solid-state semiconductor chip as the light-emitting material, where the recombination of carriers causes photon emission to produce light directly. 2. Different color temperatures: Halogen headlights have a color temperature between 2000K and 4000K, while LED headlights typically have a color temperature above 5000K. 3. Different light colors: Halogen headlights are filled with halogen gases like iodine or bromine. At high temperatures, the sublimated tungsten filament chemically reacts with the halogen, producing a yellowish light that appears warm; LED headlights convert electrical energy directly into light energy through semiconductor chips, usually emitting a blue light.
