It is confusing when someone indicates a single lighting bulb as 'E26' and 'A19'. Both the terms refer to the sizing of the bulb.

While 'A19' refers to the diameter of the widest upper part of a bulb, 'E26' indicates the size of the base of a bulb.

Still confusing? Worry not, I am here to clarify what you need to know about bulb’s sizing and what actually these different types of terminology mean-

The term A19 in bulb terminology refers to the diameter of the upper part of a bulb.

Here,

  • ‘A’ stands for Arbitrary
  • ‘19’ refers to the diameter of the upper part of the bulb, which is 19/8=2.4 inches by definition.

The length of an 'A19' bulb is around 100 to 110mm, and the width is around 60mm.

Although 'A19' is a popular light terminology in the USA, many Asian countries also know such bulbs as 'A60' blubs as well.

Are A19 and E26 refer to the same bulb?

The answer is yes and no. A light with an 'E26' base can also have an 'A19' head. In reality, most LED bulbs used in America have the same bulb pattern.

That should not necessarily mean that a bulb with an 'E26' base must have an 'A19' head. The parameters can be different on any bulb.

Therefore, the correct answer is that both A19 and E26 may or may not refer to the same bulb.
