Yes, I changed the light, but the sound continues.berkeman said:
The ballast takes the AC Mains power in (120V or 240V, etc.), and converts it to the high voltage used to turn on the florescent tube. It is basically an inexpensive switching power supply, and when it starts to fail, it can make an audible buzzing noise.Wrichik Basu said:

I thought that the term "ballast" was used for the series Inductor that's used to limit the current flowing through the very low resistance of the discharge tube, once it has struck. But I am referring to the ordinary domestic flow tubes which strikes easily with mains volts after the starter circuit has heated the filaments at each end and produced its thermionic electrons.berkeman said:
It could just be a difference in terminology country-by-country. The Wikipedia article follows the US terminology, I think.sophiecentaur said:
The buzzing sound from a tube light is caused by the electrical current flowing through the ballast, which regulates the voltage and current in the light. This current can create vibrations in the ballast, resulting in the buzzing sound.
The humming noise from a tube light is typically caused by the filament inside the bulb vibrating. This can occur if the bulb is not securely attached or if the light is not installed properly.
In most cases, the buzzing sound from a tube light is not dangerous. However, if the buzzing sound is accompanied by flickering or dimming of the light, it could indicate a problem with the electrical wiring or ballast and should be inspected by a professional.
In some cases, the buzzing sound from a tube light can be fixed by securely attaching the bulb or re-installing the light. However, if the buzzing sound persists, it could be a sign of a faulty ballast or other electrical issue that may require professional repair.
Yes, the type of tube light can affect the buzzing sound. For example, LED tube lights are known to produce less buzzing or humming noises compared to fluorescent tube lights. Additionally, older or low-quality tube lights may also produce more buzzing sounds than newer, high-quality ones.
