A halogen bulb is a type of incandescent light bulb that uses a halogen gas to increase its efficiency and lifespan. This gas allows the bulb to operate at a higher temperature, producing a brighter light while consuming less energy compared to traditional incandescent bulbs. Halogen bulbs are commonly used in homes, cars, and various types of lighting fixtures. These bulbs are known for their crisp, white light and are often used in applications where color accuracy is important, such as in art galleries or photography studios. However, they can become very hot during operation, so caution is advised when handling them.
