  • Attention! This strobe light circuit is connected to 220V, so measurements and experiments are very dangerous even after unplugging it from the mains. P1 potentiometer must have plastic swivel. The main part of this strobe circuit is the gas discharge lamp in U shape that is filled with xenon.

    To fire up the flash tube we need 5 to 10kV of electric potential. P1 determines the charging degree of C3 and the flashing frequency of the stroboscope tube. The gas discharge tube can be 60W/s. Tr1 is a trigger transformer, a small transformer with a high turns ratio, which generates a weak, but high voltage spike required to ionize the xenon gas in a flash tube.
