Early development

Invention of the dry cell

1887

The first dry cell battery was invented in 1887. Its sealed, portable construction provided the battery technology needed for practical handheld electric lighting.

Invention of the dry cell

Mass production of dry cells

1896

The first mass-produced dry cell batteries appeared in 1896, making portable electrical power more broadly available and helping enable the development of flashlights.

Portable electric lights follow mass production

1896

The invention of portable electric lights soon followed the mass production of dry cell batteries in 1896, beginning the transition from stationary electric lighting to handheld devices.

Miniature incandescent lamps enable flashlights

1899

Miniature incandescent electric lamps, combined with dry cells, made the first battery-powered flashlights possible around 1899.

First battery-powered flashlights become possible

1899

Around 1899, the combination of dry cells and miniature incandescent lamps made the first battery-powered flashlights possible.

David Misell files flashlight patent

Jan 10, 1899

On January 10, 1899, British inventor David Misell obtained U.S. Patent No. 617,592 for a battery-powered electric light. The patent was assigned to the American Electrical Novelty and Manufacturing Company.

American Electrical Novelty receives assignment

Jan 10, 1899

The flashlight patent obtained by David Misell on January 10, 1899, was assigned to the American Electrical Novelty and Manufacturing Company, linking the early invention to a manufacturing enterprise.

Improved batteries expand flashlight usefulness

1904

Improved batteries in varying sizes, appearing alongside the development of tungsten-filament lamps in 1904, made flashlights more useful and popular.

Tungsten-filament lamp developed

1904

The tungsten-filament lamp was developed in 1904. It offered three times the efficacy of carbon-filament types, improving the usefulness of battery-powered lighting.

Popularization

Flashlights become more popular

1904

The greater efficacy of tungsten-filament lamps and improvements in battery design helped make flashlights more useful and popular from 1904 onward.

Tubular hand-held flashlights available

1907

By 1907, tubular hand-held flashlights were among the available flashlight designs, establishing a familiar form for portable illumination.

Lantern-style flashlights available

1907

By 1907, lantern-style flashlights were available. They could be set down for extended use rather than held continuously.

Pocket-size penlights available

1907

Pocket-size penlights were available by 1907, providing compact illumination for close work.

Reflector searchlight lamps available

1907

By 1907, large reflector searchlight-type lamps were available for lighting distant objects.

Multiple flashlight forms established

1907

The range of flashlight types documented by 1907 included tubular hand-held models, lanterns, penlights, and large reflector searchlight-type lamps.

Flashlights rival line-operated appliances in sales

1922

The 1922 value of flashlight and renewal-battery sales was comparable to sales of many line-operated electrical appliances, indicating the commercial importance of portable lighting.

Flashlight and battery sales reach $20 million

1922

Annual U.S. sales of renewal batteries and flashlights reached $20 million in 1922, comparable to sales of many line-operated electrical appliances.

Ten million U.S. flashlight users estimated

1922

In 1922, the United States had an estimated 10 million flashlight users, demonstrating the technology's broad adoption.

Standards and modern use

Incandescent flashlight standard withdrawn

1996

A standard that described only incandescent-lamp flashlights was withdrawn in 1996, reflecting the changing technology of flashlight illumination.

ANSI publishes FL1 standard

2009

In 2009, the American National Standards Institute published the FL1 Flashlight basic performance standard in the United States.

FL1 standard defines flashlight performance

2009

The ANSI FL1 standard published in 2009 established a basic framework for describing flashlight performance in the United States.

Flashlight beam distance calculation defined

2009

The beam distance is calculated as the square root of beam intensity in candelas divided by 0.25 lux. For example, 1,000 candelas produces a working-range rating of 63 meters.

iOS adds a built-in flashlight function

2013

In 2013, iPhones were updated with iOS 7 to include a built-in function that switched on the camera flash to provide a flashlight.

LED innovation

Lumileds introduces Luxeon LED

1999

In 1999, Lumileds Corporation of San Jose, California, introduced the Luxeon LED, a high-power white-light emitter that helped enable a new generation of LED flashlights.

Luxeon becomes a high-power white-light emitter

1999

The Luxeon LED introduced by Lumileds in 1999 was significant as a high-power white-light emitter suitable for applications requiring bright portable illumination.

2018

The first laser excited phosphor, or LEP, flashlight became available in 2018, introducing a distinct long-range lighting technology to the flashlight market.

LEP flashlight market expands mainly in China

2018

By 2018, a few dozen LEP flashlights were available, mainly from China.

Key Facts

  1. The first widely recognized flashlight was developed after inventor David Misell patented a portable electric lamp in 1899.
  2. Early flashlights used dry-cell batteries and carbon-filament bulbs, but their batteries were unreliable and their light beams were weak.
  3. The American Ever Ready Company helped popularize flashlights in the early twentieth century through mass production and advertising.
  4. Flashlights became especially important for soldiers, police officers, miners, and emergency workers because they provided portable illumination without flame.
  5. Light-emitting diode (LED) flashlights, widely adopted from the late twentieth century onward, offer greater brightness, longer battery life, and improved durability.
