Abstract
A relatively infinitely incremental mode of obtaining any desired brightness of flash from an electrically operable flash-tube is attained by employing plural capacitors, each having a charging source of selectable voltage level and a unilaterally conductive element between the capacitor and the flash-tube. The unilaterally conductive element is poled to pass the charge on the associated capacitor during the discharge cycle regardless of the voltage of the charge on other of the plural capacitors involved.
