So I have a coralife power compact and a set of my lights are flickering so I'm guessing my ballest is going out does anybody know how hard they are to change
it sounda like the bulb. try swaping that bulb with another one from a nother ballest and that should tell ya if its the bulb or the ballest.
if it was me i would jest buy another bulb, youll end up using it somday if it realy is your ballest
