Hello all, hopefully someone from the thread can help. I just bought the fixture used from a fellow reefer. There is not manufactor names on it that I can see. It is a 36in fixture with 150w metal halide, two 96w PC and 4 moon blue leds. Now my issue is that its a complete fixture everything fits right but the issue I have is that the ballast that is only for the metal halide states 250w. The 150w bulbs does fire up and stay on fine. When I first got it the bulb would flicker kalvin and in go from yellow to blue. I did change the bulb and its seems to be fine but I am really wonder how this combo will effect the life of bulb and or the ballast. Part of me is thinking of switch out the sockets ends and run a 250w de or get a different ballast like a select watt one where I and set it to 150. Should I even be concerned and have read with it being an electronic ballast the bulb with only run at 150w as its the bulb that handles the drive. Let me know, thanks.
