I'm totally agreeing with RT here. I would contact the manufacturer and have them fix it. It isn't worth your life to try and mess with it unless you have experience with that sort of thing.

In the meantime, if you are currently growing get some CFL's on those plants to keep them happy until you get your light fixed.

Best of luck to you and your lighting issue.
Lynhal Reviewed by Lynhal on . cool tube not turning on???? Hi there, just got my 600w cooltube set and, wired the cables to the ballast, and turned it on but I only hear a clicking sound from the ballast and a little green light coming from inside the ballast (not a indicator), where the cable comes from the light to the ballast. So after few clicks I've turned the electric off. is there something special I shoud know? Using: - Sunmaster 600w dual specturm Lamp - mEgas Na600 Ballast Thank you in advanced Rating: 5
