An incandescent light bulb, also known as an incandescent lamp or incandescent light globe, is an electric light that produces illumination by Joule heating

power per unit area. An object at the temperature of the filament in an incandescent light bulb—roughly 3000 K, or 10 times room temperature—radiates 10,000

or a bayonet mount. The three main categories of electric lights are incandescent lamps, which produce light by a filament heated white-hot by electric

fluorescent lamp designed to replace an incandescent light bulb; some types fit into light fixtures designed for incandescent bulbs. The lamps use a tube that

have passed legislation to phase out manufacturing or importation of incandescent light bulbs for general lighting in favor of more energy-efficient alternatives

incandescent bulbs with comparable light output, which is on the close order of 16 lm/W. Fluorescent lamp fixtures are more costly than incandescent lamps

(LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and fluorescent lamps. The most efficient commercially available

electric lamp. Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes (LEDs)

magazines and newspapers reported that 25 years earlier Göbel had developed incandescent light bulbs comparable to those invented in 1879 by Thomas Alva Edison

early developer of a successful incandescent light bulb, and is responsible for developing the first use of incandescent lights used to illuminate homes
