I have a light (with an AC adapter), and whenever I turn it on, it works fine for a few minutes, then it starts flickering. It does not turn off but constantly flickers. Does anyone know what's wrong? I took the light fixture apart to make sure all the connections and soldering are good, and they are.

Also, I'm not sure I like the look of all those wires hanging out...

| | | | It may not have any user serviceable parts.
I use several cheap under cabinet fluorescent lights in my shop with no replaceable ballast or starter. If they start to flicker and a new bulb fails to fix it, it's time to replace the fixture. I've thought about going with something a bit more substantial, but they only run around ten bucks and usually last a couple years, so I just replace them when they go bad. It takes all of 2~3 minutes to swap one out.

| | | | Reenforcing the bad ballast idea but something else.
In the picture the ballast is actually on the bulb it's self so what could be happening (as with a few fixtures in my house) the voltage might fluctuate or plain just not be right a bit causing compact fourecents to not work right (or something to that effect).

My money is on 'it's the bulb'
