I have since replaced it with a smaller 13W (called 60W equivalent)
CF. This one is GE #85390.The package is labeled "NEW SMALLER SIZE!
fits more fixtures!" in white on purple on the left size. This one
fits under the globe.

I haven't seen any 13W CF with the "smaller" label. I have been using
"small" 13W CFs for the larger school house ball but they don't work for the
smaller ones in my rental property.

I will keep looking.
