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.
