The IFK-120 tube is a type of flash tube that was manufactured in the former Soviet Union. It was commonly used in photographic flash units produced in the Soviet Union and other Eastern European countries during the 1960s and 1970s.

The IFK-120 tube is a xenon flash tube, which means that it uses a gas discharge to produce a bright, short burst of light when triggered by an electrical pulse. It has a rated voltage of 120 volts and a maximum discharge energy of around 30 joules.

One of the distinctive features of the IFK-120 tube is its shape, which is cylindrical with a rounded end. This design allows it to be used in a variety of flash units, including handheld flashguns and studio strobes.

While the IFK-120 tube is no longer in production, it is still possible to find vintage Soviet-era flash units that use these tubes. However, it is important to note that these units may require servicing or repair due to their age and the fact that replacement parts may be difficult to obtain.

Overall, the IFK-120 tube is an interesting piece of photographic history that represents a unique aspect of Soviet-era technology.
