Definitions for "Electronic Ballast"
These ballasts differ from magnetic ballasts in that they generally consist of a printed circuit board with semi-conductor technology that electronically regulates the voltage to start and run the fluorescent lamps instead of physically changing the voltage as the magnetic ballast does. Due to the increased level of control, this ballast can operate at a higher current frequency range and send a more precise and efficient flow of voltage through the lamp. This creates a brighter, more efficient lamp operation. Some electronic ballasts include all electronic components, while some include a mix of electronic and magnetic components.
A ballast that uses semi-conductor components to increase the frequency of fluorescent lamp operation, typically in the 40+ kHz range. Watts loss is low, and fluorescent lamp efficacy is also increased due to high frequency operation. Used also for small HID lamps.
A high voltage transformer that excites the ions in fluorescent lamps.
