Default Dead Ballast or burnt out bulb?
I have a 2x250W HQI metal halide light fixture. Noticed one of my bulbs not on today. This sounds like a stupid question but how do I know if its my bulb or ballast that has quite? I have only had this fixture for about 8 months. The ballast that runs that bulb is cold while the other one is warm, so does that mean that the ballast is not working?
