ABSTRACT:
A flash device having a plurality of flashbulbs which operate sequentially by the use of time delay circuits to produce a longer duration of flashlight. Light reducing filters are used adjacent the flashbulbs to reduce the light intensity of the flashbulbs to obtain a more uniform light intensity during the length of the flash of all the flashbulbs, especially in the areas of overlapping of light intensity between adjacent sequential flashbulbs. A second embodiment modifies the light intensity by the placement of the flashbulbs in relation to the optical axis of the reflecting mirror.
