LIGHTING CATALOGUE

The 'topflash' is specially developed for use on pocket and instant cameras with piezo-electric ceramic cubes to provide the electrical discharge needed for ignition of the bulbs.
The unit contains 8 hard-glass flashbulbs and a blue cover divided in two groups of 4 bulbs, each bulb with its own individual reflector.
The 'topflash' is shaped as a vertical array in which the top 4 bulbs will flash in a given sequence. Flashing the last lamp of a group causes the appearance of a yellow dot.
As the 'topflash' is vertically mounted on top of the camera, the distance between the flash source and the lens opening is increased; hence, the 'topflash' acts as its own extender and reduces the occurrence of red-eye to the minimum.
The 'topflash' is suitable for black-and-white and colour films, including instant film.

MULTIPLE FLASH

The 'topflash' features the unique possibility of simultaneous, multiple flash and is, therefore, the only non-electronic flash system that offers the possibility of adapting the light output to the flash distance. As under-exposed pictures are a frequent cause of disappointment amongst amateur photopraphers, simultaneous, multiple flash is an important advantage in those situations where a single bulb proves to be entirely inadequate.
By pressing the numbers on the 'topflash', up to four bulbs can be flashed simultaneously. This will enable the photographer to take well-exposed pictures, for instance at weddings, receptions, sport events or whenever a large area or many people form the subject of a picture.
