Incandescent lamps are a type of electric light bulb that produces light by heating a thin filament, usually made of tungsten, until it glows. When electricity passes through the filament, it heats up to a temperature that emits visible light. These lamps are known for their warm, soft glow and have been widely used in homes and businesses for many years. Despite their popularity, incandescent lamps are less energy-efficient compared to other lighting options, such as LEDs or CFLs. They convert a significant amount of energy into heat rather than light, leading to higher electricity bills and increased environmental impact. As a result, many countries are phasing out incandescent bulbs in favor of more efficient alternatives.
