Which type of lamps generates light through the heating of a tungsten filament?

The choice of incandescent lamps is correct because they operate by passing an electric current through a tungsten filament, which heats up and emits light as a result. The process involves the filament reaching high temperatures, typically around 2,000 to 3,000 degrees Fahrenheit, which produces a warm, yellowish light.

Incandescent lamps are known for their simple design and ability to provide a high-quality light that many find pleasing in residential settings. This type of lighting technology has been widely used due to its affordability and the ability to instantly produce light when switched on.

In contrast, LED lamps generate light through the excitation of electrons in a semiconductor material, which is a different mechanism altogether. Halogen lamps are a type of incandescent lamp that contains a halogen gas, which allows the filament to be run at a higher temperature and improves efficiency slightly. Fluorescent lamps operate by exciting mercury vapor, which produces ultraviolet light that then stimulates a phosphorescent coating on the inside of the lamp to emit visible light. Each of these other options utilizes distinct technologies that do not involve the heating of a tungsten filament.
