Question about galaxy ballast

[wil0311]

One of my 250 watt MH lights is acting up. I have a sunlight supply 72" light fixture with the 3 250 watt bulbs and 4 t5 actinic bulbs. I have the 250 watt galaxy electronic ballast (one dual and one single) units.

Anyways the last few days the lights come on as normal with the timer and then about 10 min later one of the lights go off. It stays off for 10 min and then fires back up. It did this twice this morning and then stays on for the rest of the day. Has anyone else had any experience with this or could give me some advice on how to fix it? Thanks.

Anyone???

This might sound stupid but the first thing that comes to my mind is if the bulb that's acting up is firmly installed? I don't have the ballast or fixture you do but if the same thing were happening to me I would check all the bulbs and connections.

Thanks for posting Mike. I did switch around the chord from the defective ballast to a different light and now that light shows the same symptoms as the previous light. So now I'm pretty sure that the problem has to be in the ballast. Has anyone had any other electronic ballast do this to them before?

I've been running Blueline E-Ballast for about 3 years and 1 Gallaxy 250 E-ballast for about 1.5 years now. Never had a problem.

You might want to check the fuse in the front.

thermal protection tripping?

[wil0311]

Wouldn't the light just stay off if the fuse in the front is blown or is there something I'm missing? Something is tripping the light to go off only 10 min after starting but then it fires back up and stays on the rest of the day. So it can't be getting to hot? Maybe the ballast is starting to die, I'm not sure.

most e-ballast have protection circuits in them so if the power is interrupted there will be a delay before it fires again.

The fuse may have some corrosion on it. Other than that I do not believe there are any other servicable parts?
