How long is the life of the halogen lamp? Replace the halogen headlight every few years

The service life of different brands and types of halogen lamps is not the same, generally around 500-600 hours. Since the filament of the halogen lamp is a tungsten filament, after the bulb is used, the cooled tungsten will re-solidify on the tungsten filament to form a balanced cycle to avoid premature breakage of the tungsten filament. Therefore, the life of halogen lamps is longer than that of ordinary incandescent lamps.

Halogen headlights generally have to be replaced every one or two years. In fact, the life span is not very long. This is due to the principle of heating and luminescence of halogen lamps. During use, halogen lamps work in a high temperature environment. If they are used for a long time, they will generate heat. In severe cases, life span will be reduced. In addition, frequent switching will shorten the life of the filament. Therefore, if you feel that the headlights are not bright enough, it is recommended to replace them, and you need to change both sides together to ensure the same brightness on both sides.

The halogen bulb is made of high-temperature resistant quartz glass. If you touch it or get oily, the quartz glass will lose its luster, thereby reducing brightness and shortening its life. Therefore, when replacing and installing a halogen lamp, you need to pay attention to keeping the bulb glass case clean and don't touch it with your hands. If you touch it carelessly, you must clean it before lighting it. You can wipe it clean with alcohol.
