Abstract
Disclosed is a low pressure xenon lamp and the driver circuitry therefore for producing relatively short bursts of intense light from the lamp. The lamp, including its associated driver circuitry, can be used in theatrical, stage, movie and/or video productions to simulate, among other things, bursts of lightning. The lamp is installed in a fixture together with a power supply and a control system is provided for controlling when the lamp is turned on and off. Preferably, the control system includes manually operated switches and preferably one or more controllers can be coupled together in a series fashion, should it be desired to control the lamp for a greater number of time cycles then permitted by a single controller.
