    [class="sf"] M58 Ballast problem[/class]
    [class="nf"]I have a 250 Watt M58 dual ballast that has an
    issue. One bulb has been dimmer than the other since I had a capacitor
    go out. I replaced the capacitor and got it working. I am not sure if
    the brighter side is the newer or older capacitor. The bulbs are the
    same age and type. I have switched the quick connects to rule out a bad
    bulb and the dimly lit side switched indicating to me a ballast issue.


    Do I need to replace the other capacitor or is there another problem?[/class]

    I could be wrong here, but I don't think coils as in your ballast go bad by the voltage going low unless it was shorted out and it would not last long if that was the case.
    I read the few post on a website devoted to over driving Metal halide lights.  in order to ver drive them you change the cap for a larger one.
    it did not take much of a larger cap to up the voltage.   I would check if the new cap has a higher value than your old one

    over driving sounds like a bad idea with a reef tank as who knows what the output is and how long it will last.

    Joel, do you want to swap for the two-month-old dual ballast I'm no longer using? I feel like an *** simply for having sold that to you.

    Ryan, don't sweat it. Sh&^ happens. I bought used stuff, used stuff breaks. I will send you an email.
