Incandescent lamps

Incandescent lamps produce light by passing electricity through a thin filament, usually made of tungsten, which heats up until it glows. The heated filament emits visible light and some heat, making these bulbs energy-inefficient compared to modern options. They were widely used for over a century because they provide warm, natural light and are inexpensive to produce. However, due to their low energy efficiency and short lifespan, they are gradually being replaced by more efficient lighting technologies like LEDs and fluorescent bulbs. Incandescent lamps are simple in design and operate by directly converting electrical energy into light and heat.
