The base is the end of the bulb that connects to the reflector. There are multiple base designs and a bulb’s base type must match the socket of the reflector.

What are the Different Base Types?

There are several different bulb base types, including:
  • Screw bases
  • Bi-Pin Baes
  • Fluorescent Pin Bases
  • Compact Fluorescent Plug-In Lamp Bases
There is also a broad range of specialty bases that use a prong, wedge, or loop mechanisms (among others) for connection. Within each category of base types, there is even more variance in size, shape, and material.
