For those that didn't catch my my post and Paul's answer over in the T5 question and answer thread:

The light cutting out/off may be because of one of the transformers is over heating or from a bad T5 ballast which are housed inside the fixture. I’m not sure if the transformers are equipped with a cut off temp switch (thermal switch). If they do not it is probably one of the T5 ballasts. I don’t have my product specifications with me right now. It’s best to contact the manufacturer and trouble shoot the problem with them. I’ll be traveling the next few days and I can’t get information on the parts used right now.

One more thing. Those step up transformers were originally designed for HID ballasts (150 watts maximum) but can be used for other applications. In this case they are providing the proper voltage to the T5 HO ballasts.
