Incandescent bulbs are a type of light bulb that work by heating a wire filament until it glows, producing light. They were first developed in the late 19th century and were the most common type of bulb until recently.
Incandescent bulbs produce a warm, yellowish light that is often preferred for its cozy and nostalgic feel. However, they are not very energy-efficient, with only about 10% of the energy they consume being converted into light, and the rest being released as heat. This makes them more expensive to operate than other types of bulbs, such as LEDs or compact fluorescent bulbs.
Due to their energy inefficiency, many countries have implemented regulations phasing out the production and sale of incandescent bulbs in favor of more energy-efficient options. However, some specialty incandescent bulbs, such as Edison bulbs, are still available for decorative lighting purposes.
