With so many different LED options available, it can be tough picking out the right one for your lighting needs. That’s why each month our ‘LED Buying Guide’ brings you tips and tricks to help you make a better educated decision when purchasing your next LED bulbs and fixtures.

In the lighting industry, the base is the bottom of the lamp that is screwed into the socket. The base holds the lamp in place, connecting it to the electrical supply. Screw bases are the most common type of bases for incandescent and LED lamps.

There are two different type of bases:

  • E26 base: An E26 base, also known as a medium base, is a screw-in type light bulb that threads on the bottom, requiring you to twist the bulb to install. The ‘26’ in the name refers to the diameter of the base in millimeters. This base is commonly used in household bulbs such as A19 and floodlights including PAR20, PAR30, PAR38, BR20, BR30, and BR40.
  • E12 base: An E12 Base, also known as a candelabra or CC basem, is also a screw-in type light bulb with threads on the bottom. The ‘12’ in the name refers to a diameter of the base in millimeters. The E12 is commonly used in decorative light bulbs such as chandeliers.

In both of the above bases, the ‘E’ refers to Thomas Edison.
