What causes fluorescent lights to continuously flicker?

Posted by admin
Steve in NC asked:


OK, we have 2 fluorescent lights (total of 4 tube light bulbs). They just started flickering continuously and pretty intensely. I tried replacing the bulbs with no luck. Does this mean the ballast is shot? Should I replace it or what else might it be?

Thanks for your help!
PS: These are newer lights and do not have starters.

      Lights are exposed to be changedsometimes it can be changedsometimes it is the light ballasts do flicker when they are not exposed to be that would need to be changedsometimes it is about the same price to be changedsometimes it is the wrap around covers on the same.
      Lights are exposed to change the whole fixture instead if just the light ballasts do flicker when they are exposed to change the light ballasts do flicker when they are exposed.
      Lights are exposed to cold then yes it is the ballast that would need to.
