Halogeenivaloat

Halogeenivaloat are a type of incandescent light bulb that contains a small amount of a halogen gas, such as iodine or bromine. This halogen gas allows the bulb to operate at a higher temperature than a standard incandescent bulb, resulting in brighter light and a longer lifespan. The halogen cycle is the chemical process that allows these bulbs to function efficiently. When the tungsten filament heats up, it evaporates and forms tungsten halide gas. This gas then circulates to the cooler parts of the bulb, where it redeposits the tungsten back onto the filament. This process prevents the filament from thinning and breaking as quickly as it would in a regular incandescent bulb.

Halogeenivaloat are known for their excellent color rendering, meaning they can display colors accurately. They are often used in applications where good color quality is important, such as in spotlights, automotive headlights, and some residential lighting. While they are more energy-efficient and last longer than traditional incandescent bulbs, they still consume more energy and have a shorter lifespan compared to LED or fluorescent lighting. However, their compact size, instant-on capability, and warm light output remain advantages for certain uses. When a halogeenivaloat reaches the end of its life, the filament will eventually break, causing the bulb to fail.
