The present disclosure relates to a flash generator for providing power supply to a flash tube so that the flash tube rapidly provides a light output adapted to FP-sync, Flat Peak. The flash generator comprises a capacitor bank, an output and a switch configured to switch a current flow from the capacitor bank via the output to provide a variable power via the output. The flash generator further comprises a controller for controlling the switch, whereby by controlling the on time of the switch, the generator is operative to provide, during a time period of 100 to 2000 &#x3bc;s during a peak time period within the time period, an average power at least 4 times higher than the average power provided during the other time period within the time period, whereby the flash tube during the peak time period becomes fully ignited.
