Problem with halide shutting off

[mikexnxike01]

Hey guys I have a question/problem. I bought a used aqua medic 250w + 2 t5 fixture the other day. When I go to turn on the lights everything turns on fine but the halide bulb shuts off after about 5 minutes. I can still hear the ballast buzzing but no light from the bulb. Any suggestions of why it just turns off like this? Thanks

Mike

Do you know how old the bulb is?

Try a new or confirmed working bulb. If it stays on then you're golden...if not then it's the fixture/ballast. At that point try a different confirmed working ballast...and so on. Process of elimination...start with the bulb though since its the easiest to replace.

switch bulbs with the one working first to rule out a bad bulb. then if it still does not work, its more then likely a bad ballast.

i bought the fixture used therefore i dont have the old bulb. the owner said the bulb was only 2 months old

Trust but verify...

Do you have a buddy with a spare bulb you can test with? Or just go buy one (you'll need to at some point anyways) and try that.

dont know of anyone with a bulb off hand. the fixture does not have any fans in it so i assume its supposed to run without one but i hooked up a little computer fan to one side of the fixture and the light stayed on for like 10 min instead of 5 but still shut off. does that mean anything?
