From the discription in your signature, your light sounds like an Odessya fixture or a Coralife Fixture.

The First of the two is a very budget fixture that comes with a few weak points that often result in a yellowish light. With a little elbow grease and a few dollars, this fixture can be made into quite a good one. There are a lot of threads about their stuff but take it with grain of salt.

If it's a Coralife, then I'm guessing that the bulbs may just need replacing.
