Abstract
A lighting system that includes a lamp and a control circuit configured to apply signals to the lamp in pulsed mode operation. The lamp may employ ferroelectric ceramic cathodes to enhance life of the lamp when used with the pulsed mode drive circuitry. The drive circuitry applies signals within a desired frequency range to lower input power while providing enhance output within a desired wavelength band, such as 365 nm to make use of an afterglow regime from an emissive medium within the lamp.
