ABSTRACT:
A photographic flash device comprising a grip portion and a flash unit removably attachable thereto. Both the grip portion and flash unit house battery-powered DC-DC converters which cooperate upon attachment of the flash unit to the grip portion in charging a main discharge capacitor. A source switch permits charging of the discharge capacitor by only one of the DC-DC converters, and a safety switch prevents operation of at least one of the converters when the flash unit is not attached to the grip portion.
