Halogen lamps are a type of incandescent light bulb that use a halogen gas to increase efficiency and lifespan. They produce bright, white light and are commonly used in homes, cars, and outdoor lighting. The halogen gas allows the filament to operate at a higher temperature, resulting in improved brightness and a longer life compared to traditional incandescent bulbs. These lamps are available in various shapes and sizes, including PAR and MR types, making them versatile for different applications. Halogen lamps are often favored for their ability to provide excellent color rendering, making them suitable for tasks that require good visibility, such as art studios and workshops.
