I bought a Flukers 5.5-inch small lamp with dimmable switch - the store did not have a matching bulb to go with this fixture.
I bought a Reptisun 5.0 UVA/UVB CFL, which of course fits the socket, but is to large for the lamp and extends beyond the fixture. So, it looks like this lamp can only be used with incandescent bulbs - so do I have to buy a "Blue" day bulb and a "Red" night bulb to provide the heat that my PacMan frog needs?
