Usually, a small amount of flickering should not be of concern unless it’s constant or the bulb starts to dim, then it needs to be replaced.

If a new bulb flickers or takes a long time to start up, then it suggests that the starter, which sends a steady stream of electrons between the two filaments is faulty. The ballast controls the amount of current that is sent to the filaments. If this is faulty, it will allow too much current which may vaporize the filaments or even cause the bulb to explode.
