I have replaced two 18"fluorescent lights in my RV ceiling. The problem is that they only stay on for approx. 10 minutes then they go out. If I turn them off for 10 min and then back on, it does the same thing. However, If I let them dangle from the ceiling by the wires... the light fixture stays on! What suggestions do you have to help me fix my electrical problem. Thanks for any input you have.

Do these light fixtures have any kind of transformer or ballest in them?

Here is a link to the light that was purchased. Recessed Light 30 Watt, 18” - Item - Camping World (http://www.campingworld.com/shopping/item/recessed-light-30-watt-18-/34482)
I'm not sure that it has a ballest or transformer.

The ballast or teansformer is heating up when the light is on and shutting down. The cooling off and the light works again.
