I've got a 48" aqua medic hood with 2 250watt de halides and 2 T5's. One of the halides quit working and when I checked the bulb I noticed the metal clamp in the hood had broken. I assumed this was the problem since the ballast made a humming noise when you turned it on. Today I replaced the bulb socket but it still does not work. I plugged it into the other ballast and the light fired so it is the ballast. As I stated it makes a humming noise when I turn it on, it just doesn't fire the bulb. Is there a part such as a fuse that might need replacing, or does this require a new ballast?
This is a dual magnetic setup in a single housing.
