Yes, if more than 4 years old, those are compact fluorescent lamps with an external ballast.
There are replacement lamps with the same base that are LED and require that you bypass the ballast (rewire the lamp). If I had a bad lamp or a bad ballast, I would replace it with an LED. You can find them on ebay and amazon, as well as other dealers. But be extremely careful to make sure you are getting a bulb that will fit and meets your needs. Also, you need to know how to wire it. It isn't a simple plug-in replacement.
