I was wondering if anyone has a suggestion.
I have a 400 Watt Metal Halide light on my tank with a single-ended bulb. Lately, the light has only been coming on every once in a while. Even though there is power going to the ballast, and it gets hot, the light doesn't work. I know the bulb is good because it still works sometimes, and is only a few months old.
Any suggestions on what to check? Could there be something inside the ballast that isn't working?
