1. A disinfection apparatus, comprising:
a germicidal pulsed light source arranged within the disinfection apparatus such that germicidal light generated from the germicidal pulsed light source is projected exterior to the disinfection apparatus;
trigger voltage circuitry for applying a trigger voltage to the germicidal pulsed light source at a set frequency greater than approximately 3 Hz;
power supply circuitry;
one or more electrical charge storage devices coupled to the power supply circuitry and to the germicidal pulsed light source;
pulse duration circuitry coupled between the one or more electrical charge storage devices and the germicidal pulsed light source;
a processor; and
program instructions executable by the processor for receiving data regarding characteristics of a space in which the disinfection apparatus is to be operated.
