Is it necessary to replace halogen lamps?

[LaEsther]

Halogen lamps do not need to be replaced. Halogen lamps are a variant of incandescent lamps. Their working principle involves injecting halogen gases such as iodine or bromine into the bulb. At high temperatures, the sublimated tungsten filament chemically reacts with the halogen, and the cooled tungsten re-solidifies on the filament, forming a balanced cycle that prevents the filament from breaking prematurely. Precautions for using halogen lamps include: 1. The glass shell of halogen bulbs is made of quartz material. Do not touch the bulb with hands or a cloth before lighting it, as this may cause the bulb to lose its luster and become irreparable; 2. If the halogen bulb gets dirty, it should be cleaned before ignition, using alcohol-soaked cotton balls for scrubbing.
