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.
A ballast that uses electronic circuitry to provide the voltage and current that are needed to start the lamp(s) and to maintain its operation. Electronic ballasts weigh less than magnetic ballasts and operate more quietly. Electronic ballasts operate lamps at a higher frequency than magnetic ballasts (20,000 to 60,000 hertz compared to 60 hertz), which eliminates flicker and increases efficacy. See also ballast.
A device that uses electronic components to regulate the voltage of fluorescent lamps.
A ballast that uses semiconductor components to increase the frequency of fluorescent lamp operation-typically in the 20-40 kHz range. Smaller inductive components are used to provide the lamp current control. Fluorescent system efficiency is increased due to high frequency lamp operation.
A newer type of ballast commonly used for fluorescent lighting. A ballast contains an electronic circuit that produces the voltage needed for lighting.
(a.k.a. High Frequency or Solid State Ballast) - A power-regulating device that consumes approximately 25% less energy than magnetic ballasts and controls lamps by means of electronic components. Lamp operation must be above 1000 Hz and is typically about 25 kHz (25,000 cycles per second) which eliminates flicker.
A short name for a fluorescent high frequency electronic ballast. Electronic ballasts use solid state electronic components and typically operate fluorescent lamps at frequencies in the range of 25-35 kHz. The benefits are: increased lamp efficacy, reduced ballast losses and lighter, smaller ballasts compared to electromagnetic ballasts. Electronic ballasts may also be used with HID lamps, but the circuits are quite different, there are few designs at present and only minor lamp efficacy improvements result.
