An **incandescent light bulb**, **lamp**, or **globe** is an **[electric light](https://answers.mindstick.com/qa/51943/electric-bulb-is-filled-with)** that has a wire filament that has been heated till it glows. To protect the filament from oxidation, it is encased in a glass bulb with a vacuum or inert gas. Terminals or wires inserted in the glass provide current to the filament. A bulb socket provides both mechanical and electrical support. \
**[Incandescent bulbs](https://answers.mindstick.com/qa/51943/electric-bulb-is-filled-with)** come in a variety of diameters, light outputs, and voltage ratings, ranging from **1.5** to **300 volts**. They don't need any external regulating equipment, have cheap production costs, and work on both alternating and direct current. \
As a result, the incandescent bulb found widespread application in residential and **commercial lighting**, as well as portable lighting such as **table lamps**, **automotive headlamps**, and **flashlights**, as well as decorative and advertising lighting. Prior to **Joseph Swan** and **Thomas Edison**, historians **Robert Friedel** and **Paul Israel** mention inventors of incandescent lamps. \
They find that **Edison's** version outperformed the competition due to a combination of three factors: an effective incandescent substance, a higher vacuum than the competition, and a high resistance that allowed power distribution from a centralized source economically viable. \
**Edison's** success, according to historian Thomas Hughes, was due to his creation of a full, integrated system of **[electric illumination](https://answers.mindstick.com/qa/51943/electric-bulb-is-filled-with)**[.](https://answers.mindstick.com/qa/51943/electric-bulb-is-filled-with)
