Old type of flash light that ignited by simple battery/capacitor system and was used once.
Flashbulb.
Light source based on ignition of combustible metal wire in a gas filled transparent envelope. Popular sizes are usually blue-coated to give light approximating to daylight. Flash bulbs come in various sizes and types.
Flashbulbs took longer to achieve full brightness and burned for a longer duration than electronic flashes, and slower shutter speeds (typically from 1/10 to 1/50 of a second) were used on cameras to ensure proper synchronization.
Flashbulbs use magnesium foil that burns when triggered by an internal electrically fired squib. They usually burn for about 1/30 of a second and take a little while to reach full brightness.

Standard flashbulbs (designed for "M" [20ms to peak output] and "F" [5ms to peak output] synchronization) did not have a long enough peak light output for the "FP" sync even though the duration of their light output is very long compared to an ...
Flashbulbs - A special flashbulb that can be used at certain shutter speeds is called "FP" where the initials stand for Focal Plane.

The flashbulbs illuminate the scene during image capture creating thin slivers of shadow along the depth discontinuities.
I didn't have any strobe arms to go with it, and the beam was pretty narrow, but at least it was better than flashbulbs. About that time I began hearing about another kid on the island who was doing some really nice underwater photography.
“If I’m after a really big image of a large passage I’ll use the flashbulbs favoured by press photographers, which are full of magnesium wire.
FLASH - (1) A brief, sudden burst of bright light from a flashbulb or an electronic flash unit; (2) An artificial light source that provides brief, bright illumination of a subject in order to properly expose photographic film; ...
This article only covers electronic flash. Flashbulbs are a little different; read about them specifically if you want to use them (though they're rare, normally impractical, and best saved as collector items now).
Flash A brief, intense burst of light from a flashbulb or an electronic flash unit, usually used where the lighting on the scene is inadequate for picture-taking.
Flash. 1. A short burst of light emitted by a flashbulb or electronic flash unit at the same time the film is exposed. 2. The equipment used to produce this light.
