Is there a cfl light bulb made that can be used in place of a halogen bulb that plugs in with the two little prong things?

I wouldn't think so, you need a ballast/transformer, I would consider an LED replacement. What bulb are you thinking of?

Just something in the bathroom above the mirror with the four halogen bulbs about 200 watts and the kids use them only and I will get a whole new fixture if I have to just wondering if they made such a thing. Thanks
