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.

A camera with a simple and compact structure can emit light using a discharge tube. A camera includes a circuit board including a contact connected to a trigger coil, a discharge tube that can discharge electricity, a housing accommodating the discharge tube, a reflector being conductive, urged toward the housing, and attached to the housing, and a wire having an end electrically connected to the contact on the circuit board and a distal end with an exposed conductor. The housing is attached to the circuit board. The housing includes a receiving portion receiving the reflector, and a sidewall located lateral to the receiving portion and extending perpendicular to the circuit board. The sidewall of the housing has a cutout guiding the wire inside the housing and holding the wire to have the distal end of the wire held between the reflector and the receiving portion.
