On one of my tanks I have a 4ft All Glass Normal Output light fixture. It has developed this problem: the bulbs will only light if they are loosened, and held just so by hand. If you twist tighten them how they're suppose to be, all that happens is the ends of the bulbs glow. Any suggestions on what to fix? Could it be a starter or ballast problem, or time for a new light? Thanks for any help.
