How long is the life of an infrared heating lamp?
The life of an replacement infrared halogen lamp is not a fixed value, it is affected by a combination of factors. Generally speaking, its life may be between 2000 and 10000 hours, but this is just a rough range.
The influence of the working environment
Temperature factor: If the working environment temperature of the Quartz IR Halogen Heating Element is too high, it will accelerate the aging of the filament. Because the thermal motion of the atoms of the filament is more intense at high temperatures, it is easy to change the structure of the filament material (such as tungsten filament), causing the filament to become thinner or even break. For example, the service life of a heating lamp used in some industrial high-temperature environments may be shortened by 30% – 50% compared to that used in normal room temperature environments.
Humidity factor: A high humidity environment is not conducive to the service life of Shortwave Halogen Infrared Lamps. When the ambient humidity is high, moisture may enter the interior of the lamp body, and during the temperature change of the filament, it is easy to cause a short circuit or accelerate the oxidation of the filament. Especially when used in some humid industrial plants or outdoor environments, the service life of the heating lamp may be reduced to less than half of the nominal life.
Dust and impurities: If there is a lot of dust or corrosive impurities in the working environment, these substances may adhere to the surface of the heating lamp or enter the interior of the lamp body. Dust will affect the heat dissipation performance of the Halogen Heater Replacement Bulbs, causing the local temperature of the filament to be too high; corrosive impurities may corrode the filament or other parts of the lamp body, such as the lamp holder and lampshade. For example, the service life of Heating Infrared Bulbs used in foundries may be greatly shortened due to the large amount of dust and metal debris.
Influence of product quality
The service life of IR Heating Lamps of different brands and quality grades is also different. High-quality Short Wave Infrared Heat Lamps use high-quality materials (such as high-purity tungsten filaments) for their filaments, and are more sophisticated in manufacturing processes, and the quality of components such as lampshades and tungsten halogen lamp holders is also better. For example, some well-known brands of halogen heating bulbs may have a service life of about 10,000 hours through strict quality control and advanced manufacturing technology; while some poor quality replacement infrared halogen lamps may have a service life of only 2,000-3,000 hours due to impure filament materials and rough manufacturing processes.
