flashbulbs made by Meggaflash
Description
A flashbulb is a device which produces a lot of light as a result of the combustion of material in an oxygen rich atmosphere contained within a glass envelope or bulb. The combustible material can be magnesium, aluminium or zirconium.
1) They produce a "softer" light output with longer duration due to the combustion characteristics. As the material ignites, the "fire" starts slowly at first, producing low light output, increasing rapidly to a peak, then, declining as rapidly as it rose, to low and zero light output. The duration of the light produced can be from 4 milliseconds to 2 seconds, depending on the type and design of flash bulb. This can help to produce photos with more definition with the use of smaller grain film with smaller aperture settings.
2) Larger flashbulbs can produce more light than any portable electronic flashgun and this can be useful if mains or grid electric power is not available to supply electrically powered strobe lights or other types of lighting. Larger format architectural photography or cave photography are typical applications for flashbulbs.
