Halogen

Halogen bulbs are a type of incandescent lighting that offers a brighter and more energy-efficient light compared to traditional incandescent bulbs. They work by enclosing a tungsten filament within a compact quartz envelope filled with a halogen gas, such as iodine or bromine. When electricity passes through the filament, it glows hot to produce light. The presence of halogen gas increases the efficiency and lifespan of the bulb by regenerating the tungsten filament, allowing the bulb to burn more brightly and last longer.

Halogen bulbs are known for their excellent color rendering and ability to produce a crisp, white light, making them ideal for applications where precise lighting is essential, such as task lighting, retail displays, and outdoor security lighting. They are available in a wide range of shapes, sizes, and fittings, including spotlights, floodlights, and traditional bulb shapes, making them versatile for various lighting needs.

Despite their benefits, halogen bulbs are being phased out in many regions due to their higher energy consumption compared to LED and CFL options. However, they remain a popular choice for specific applications where high-quality light is crucial. When using halogen bulbs, it's important to handle them carefully, as the quartz envelope can be damaged by oils from human skin, potentially affecting the bulb's lifespan.
