Four electrode cold cathode gas discharge tube designed for use in stroboscopes. An arc between the cathode and anode is triggered by one or both trigger electrodes, creating a bright flash of light. The peak arc current should lie between 5 and 250 A and is normally delivered by a capacitor.

This item is from either ICIANZ or Monash University; its exact provenance cannot be determined (as of March 2013).
The Ferranti Sirius in the Museum Victoria collection was donated by Monash University in 1975. The University had acquired the computer from ICIANZ (Imperial Chemical Industries of Australia and New Zealand) in 1967.

Monash University donated hardware, software and paperwork to Museum Victoria. The donation included items from both ICIANZ and Monash University, but it has not been always possible to identify to which institution every item belonged. In March 2013, a researcher from Monash University Computing Museum identified the sources of as many of the items as she could.
