WebJul 6, 2016 · Without going into detail about how these lamps work, each is filled with gases that become excited and emit photons (which we perceive as light) when charged by electricity. Since they do not have a filament to resist or regulate this electricity, the ballast does … WebThe indicator light and test button are usually the same. An Emergency Ballast is a rechargeable battery pack that looks like a fluorescent ballast and provides emergency light functions inside of a fluorescent tube fixture. They work the same as emergency lights. When there is a power failure, the emergency ballast will provide power to one or ... 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.
