WebOct 9, 2024 · The ballast takes in electricity and then regulates current to the light bulbs, stabilizing the output of the light. In other words, this is what makes the light stay lit. A fluorescent light has to have a ballast in order to work, without it, the current would increase as it passed through, ruining the lamp all together.
A quadrac type light dimmer can be used with a dimming ballast, which maintains the heating current while allowing lamp current to be controlled. A resistor of about 10 kΩ is required to be connected in parallel with the fluorescent tube to allow reliable firing of the quadrac at low light levels. See more An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current … See more Fixed resistors For simple, low-powered loads such as a neon lamp, a fixed resistor is commonly used. Because the … See more An electronic ballast uses solid state electronic circuitry to provide the proper starting and operating electrical conditions to power discharge … See more For a lighting ballast, the ANSI ballast factor is used in North America to compare the light output (in lumens) of a lamp operated on a ballast compared to the lamp operating … See more An electrical ballast is a device that limits the current through an electrical load. These are most often used when a load (such as an arc discharge) has its terminal voltage decline when current through the load increases. If such a device were connected to a … See more An inductor, usually a choke, is very common in line-frequency ballasts to provide the proper starting and operating electrical condition to power a fluorescent lamp or HID lamp. (Because of the use of the inductor, such ballasts are usually called magnetic … See more Preheating This technique uses a combination filament–cathode at each end of the lamp in conjunction with a mechanical or automatic (bi-metallic or electronic) switch that initially connect the filaments in series with the ballast to … See more WebBallasts with a high ballast factor can help in this goal by driving more light from fewer fixtures. Ballast factor typically runs between about .70 and 1.20, which means that a …
WebJan 11, 2024 · How do ballasts work? In order for a ballast to work, it must have two things: an input and an output. The input is the wire coming from the power supply. The output is the wire that goes to the fixture. For most ballasts, there are two wires going to the fixture: one for power and one for control.
