How many hours is the lifespan of a halogen lamp?

Halogen lamps generally have a lifespan of 2500 hours. Here is some relevant information about halogen lamps: 1. Halogen bulbs, referred to as halogen bulbs or halogen lamps, also known as tungsten halogen bulbs or quartz bulbs, are a variant of incandescent lamps. 2. Working principle: When the filament heats up, tungsten atoms evaporate and move towards the glass tube wall. When approaching the glass tube wall, the tungsten vapor cools to about 800°C and combines with halogen atoms to form tungsten halide. Tungsten halide decomposes back into halogen vapor and tungsten when heated again. Through this regenerative cycle process, not only is the lifespan of the filament greatly extended, but also, since the filament can operate at higher temperatures, higher brightness, higher color temperature, and higher luminous efficiency are achieved.
The lifespan of halogen bulbs is generally around 500 to 1,000 hours, which I know from personal experience as I've driven several cars that used them. If you don't drive much at night in the city, the bulbs can last over 800 hours, but since I frequently drive long distances at night, mine burned out in just six months. The actual lifespan depends a lot on usage habits—like frequent on/off switching or driving on bumpy roads, which can accelerate filament wear. I recommend regularly checking for dimming brightness and replacing them as soon as they start to fade to avoid nighttime driving risks. Compared to newer LED lights, halogen bulbs are cheaper but consume more power, though they're easier to replace—just a few minutes of DIY work. Overall, adjust based on your driving conditions and prioritize safety.
