An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation .
A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage. Lamp bulbs with dual carbon filaments were ...

Lamps usually have a base made of ceramic , metal, glass, or plastic which secures the lamp in the socket of a light fixture , which is often called a "lamp" as well.
One of the rare toys that actually accomplishes something, the Easy-Bake is heated by a 100-watt light bulb. What could be a more permanent Using Your Easy-Bake Oven Is About to Become Difficult
The Easy-Bake Oven is a working toy oven introduced in 1963 and manufactured by Kenner and later by Hasbro. [1] [2] The original toy used a pair of ordinary incandescent light bulbs as a heat source; current versions use a true heating element.
Note that incandescent light bulbs from flashlights are not used because the lemon battery is not designed to produce enough electric current to light them. Such a battery typically produces 0.001 A (1 mA) of current at a potential difference of 0.7 V; these values are multiplied together to determine the overall power of 0.0007 W (0.7 mW).
The incandescent light bulb, an early application of electricity, operates by Joule heating: the passage of current through resistance generating heat. Electricity is a very convenient way to transfer energy, and it has been adapted to a huge, and growing, number of uses. [75]
People usually use nightlights for the sense of security which having a light on provides, or to relieve fear of the dark, especially in young children.Nightlights are also useful to the general public by revealing the general layout of a room without requiring a major light to be switched on, for avoiding tripping over stairs, obstacles, or pets, or to mark an emergency exit.
