Halogen bulbs are a type of incandescent bulb that uses a small amount of halogen gas, such as iodine or bromine, to improve their efficiency and lifespan. They were first introduced in the 1950s and have become a popular option for a variety of lighting applications.
Halogen bulbs produce a bright, white light that is similar to natural daylight, making them a good choice for tasks that require high levels of detail, such as reading or working. They are also more energy-efficient than traditional incandescent bulbs, with a longer lifespan and higher light output.
However, halogen bulbs still produce a significant amount of heat and are not as energy-efficient as other types of bulbs, such as LEDs or compact fluorescent bulbs. They also require careful handling, as the oils from human skin can cause the bulb to overheat and fail prematurely.
