This morning I was able to take my fixture down. It turns out my bulb is burnt out, but its only 4 mos old. Its a phoenix 14k de, and I only run it 4 hours a day. This seems a little pre-mature for bulb failure. I have had another problem for the past few months I forgot to mention though. Every so often, I will notice my light will just shut off in the middle of its cycle. I run it off a reefkeeper, so it has a 15 min delay before it allows the ballast to refire. Is it possible I'm overloading the outlet I'm using? I always assumed if I overloaded the outlet, everything would shut off and trip the breaker, but this has never happened. Only the light shuts off and comes back on in 15 mins. I'm only using about 600watts to power my whole system, and 200watts of that is my heater, and that doesn't come on often. I wouldn't think that is enough to overload a single outlet.
