Does ballast make noise?

People also ask, do HID ballasts make noise?
The buzzing you hear is the unit pulsing on and off like a PWM controlled motor. If that does not seem to help, try swapping the ballast to the opposite side to see if the noise continues or stays on the original side with the new ballast.
Secondly, do I need to remove the ballast to use an LED bulb? LED technology does not require a ballast to regulate the amount of energy flowing to the lights. Additionally, removing the ballast will reduce energy usage and result in even great cost-savings as ballasts continue to draw more power than necessary.
Considering this, how do I know if a ballast is bad?
If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:
- Delayed start.
- Low output.
- Inconsistent lighting levels.
- Switch to an electronic ballast, keep lamp.
- Switch to an electronic ballast, switch to a T8 fluorescent.
Why do ballasts buzz?
When current is present and running through the ballast it creates a magnetic field which in turn slows the current – keeping it in check. The ballast makes this buzzing noise through magnetostriction – a phenomenon that takes place when the magnetic field produced by the ballast physically squeezes the iron core.
