    Fluorescent light fixtures are popular because of their energy efficiency and long lifespan compared to incandescent bulbs. However, fluorescent lights produce light in a different way from lights that use resistors, and they require specialized equipment in order to operate. The ballast is one of the most important parts of the fluorescent lamp, and a magnetic core was part of its original makeup. One characteristic of core and coil magnetic ballasts operating at 60 Hz, is the generation of audible noise. Noise can be increased by high temperatures, and it is amplified by certain luminaire designs. The best ballasts use high quality materials and workmanship to reduce noise. Noise is rated A, B, C, or D in decreasing order of preference. An "A" rated ballast will hum softly; a "D" rated ballast will make a loud buzz. The number of ballasts, their sound rating, and the nature of ambient noise in the room determine whether or not a system will create an audible disturbance....

    The fluorescent ballasts are employed in light bulbs to control the flow of electricity from a power source to the light source. When a steady flow of electricity to the light bulb is disrupted, the bulb will flicker. There are two types of ballasts used for lighting including electronic ballasts and magnetic ballasts. Magnetic ballasts are an older technology, fluorescent light bulbs that feature magnetic ballasts are much more likely to flicker than electronic ballasts. Electromagnetic ballasts are designed to condition the 60 Hz input voltage to the electrical requirements of the lamps. A magnetic ballast alters the voltage, but not the frequency. Thus, the lamp voltage crosses zero 120 times each second, resulting in 120 Hz light output oscillations. This results in about 30% flicker for standard halophosphor lamps, operated at 60 Hz. The flicker is generally not noticeable but there is evidence that flicker of this magnitude can cause adverse effects, such as eyestrain and headache....
