ABSTRACT:
A variable candela strobe unit couples a substantially constant trigger voltage to a trigger electrode of a gas discharge tube irrespective of the voltage provided across the tube which is specified by a selected candela output value. The trigger voltage is great enough at low candela output settings to provide reliable triggering. It is not high enough even at the highest output settings to cause arcing of the associated step-up transformer.
