A multiplex strobe light in which several ionized gas flash tubes are fed in parallel from a common power and trigger circuit. The common power circuit has a capacitor which is connected across a charging voltage and all of the flash tubes. The common trigger circuit has an SCR gated on by a zener when the charge on the capacitor reaches the desired voltage. Each flash tube has its own transformer with the secondary connected to its control electrode and the primary connected to a capacitor discharged through the SCR so the flash tubes are turned on simultaneously and share the power capacitor discharge.
