Abstract
A ballast-free energy-efficient ultra-violet material treatment and purification system and method having an ultraviolet (UV) source comprising a gas discharge UV lamp having spaced electrodes, a source of a high-frequency (about 100 kHz to about 1.5 MHz) alternating-current square-wave voltage and connected directly to the spaced electrodes to non-thermionically start and operate the gas discharge UV lamp. Proportionate control of the intensity of UV generation is provided. A plurality of UV lamps are serially connected and started and operated by a high-frequency alternating-current square-wave voltage.
