Problem with fixture
Hello - I purchased a fixture a few years ago that has 4 T5 bulbs and 2 HPS bulbs built into it. I had to move right after buying it and I didn't have the space for it so it sat in a closet. But now after moving again I can use it. I set it up yesterday and it worked fine all day. Today the T5's won't stay on. They go on for a few seconds then off for a while and then back on for a few seconds.
Any advise on what might be causing this and what I can do to fix it? Obviously it's no longer under warranty. Thanks.
