Abstract: Flash tubes for photographic use, in particular a flash tube is adapted to provide a light output adapted to FP-sync, Flat Peak. The flash tube includes a length of glass tubing enclosing a gas for use in the flash tube, a cathode inside a first end part of glass tubing and an anode inside a second end part of glass tubing. The cathode includes an element that helps to ionize the gas that is wound around the cathode, such that a spark stream starts from the upper part of the cathode and is prevented from spreading down wards on the cathode and changing the arc length during the light output adapted to FP-sync.

Abstract: A support ring is for mounting of a soft box on a light source. The support ring includes a connector for attachment of the support ring to the light source, and at least one cavity configured to receive support pins of the soft box. The cavity further includes a first and a second support element arranged to counteract a torque from the support pins, when the support pins are in an inserted position in the cavity. At least one entry element on a radial outside of the cavity is arranged to counteract a force required to bend the support pin to an angle where the support pin can be inserted into the cavity.

Abstract: A generator for a flash device includes a first capacitor bank with at least one capacitor of a first type. The first capacitor bank is connectable to a charger via a first switch, and connected to an output via a first component which only allows current flow from the first capacitor bank to the output. A second capacitor bank includes at least one capacitor of a second type connectable to the charger via a second switch, and connected to the output via a second component which only allows current flow from the second capacitor bank to the output. The generator individually controls the first and second switches so that each of the first and second capacitor banks can be individually charged to the same or different voltages. A flash trigger switch is connected to a trigger output for providing a trigger voltage to a flash device connectable to the generator.
