Web1. Fluorescent desk lamps usually operate with separate ballast that connects to an outlet (which looks almost like an ac/dc adapter). – venny. Oct 25, 2015 at 17:48. 1. @venny: You are right, of course. It was just mounted at the far back of the armature where I didn't notice it. I feel a bit stupid now. Electronic ballasts are often based on switched-mode power supply (SMPS) topology, first rectifying the input power and then chopping it at a high frequency. Advanced electronic ballasts may allow dimming via pulse-width modulation or via changing the frequency to a higher value. 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 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 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 … See more An electrical ballast is a device that limits the current through an electrical load.
