That sucks to hear. Is the light cycling? (Igniting for a little while, then cutting off, then repeating the process continuously.) Or does it just take forever to fire up... but stays lit once it gets going? If it's the latter, and your ballast is a pulse start system, it sounds like the igniter or capacitor may be taking a crap on you.
