As you can see, a normal sized screw in bulb is called an E27 fitting. The "E" stands for Edison. The smaller version is called a Small Edison Screw and it's also known as an E14.
Normal sized Bayonets are called B22s. Presumably the "B" stands for Bayonet. The smaller version of the Bayonet is called a B15.
Concerned that you don't have the right fitting? The good news is for very cheap you can find conversion kits between the various formats.
