E26 VS A19: Can I use A19 instead of E26?

You might have heard the term ‘E26’ when you went to purchase a bulb for yourself. And there is a possibility to come across the term ‘A19’ too. Have you ever tried to learn about this particular indicating digits and letters?

Both the combos of digits and letters mean two different models of the bulb!

Surprising, huh?

Yes, both of them indicated two different bulb models. This time we are going to give you the clarity of both these similar yet different bulbs. Start the learning from here.

E26 VS A19

About E26

In bulb industries, E26 is a very popular and common phrase. This indicates the bulbs are not lighting parts information.

In most cases, this number or word phrase is used because of the wide uses.

Here, the ‘E’ is for Edison Screw, and the digit ‘26’ refers to the diameter in millimeters. The diameter of the light's lower part is indicated, where we can see the ring formation of metal that attaches the bulb in the bulb-holder and connects it with electricity. The diameter is approximate ‘1 inch’ to measure.

You will find a metal contact point just about 10 mm in diameter that works as an electric ‘hot’ point on the tail of the bulb.

Since E26 indicates the shape and diameter of the cap or base of a bulb, you can simply find out only by looking at the cap of the bulb. We all know that the cap is there to connect the light with the holder and supply electric power. Or you can look at the light body to find out the model as almost all the manufacturers print the mounting base model on the bulb.

In the USA and Japan, these E26 bulbs use 120V AC. This standard value of alternating current powers most of the daily machinery. Won’t need to rewire your connections for these bulbs. 

About A19

The ‘A19’ is likely to be the same product as the previous one. Mass people would hardly find any differences between these two models.

But, yes. They are not the same bulbs you are deceived by. 

The term ‘A19’ is used to mean the overall shape and dimensions of a bulb. This is the classic bulb model that started the journey right from the incandescent era of light bulbs.

The A-series offered a load of models after that. In this particular model of bulb, you will find the same cap modular that is offered by E26 model bulbs. Since we have stated that these digits and numbers indicate the bulb's shape and size, it has nothing to do with the mounting cap/base.

The shape is identical with an upside-down pear to relate. Most of the incandescent bulbs are the same shape. And the diameter is 19 multiplied by one-eighth of an inch that is 2.4 inches roughly with the widest part of the bulb.

The electric hot point is there to connect with the main supply with the exact diameter we find on others.

A19 bulbs are also A60 in some countries where the metric measurement system is not in use.

As we can see the difference and similarities in the chart we can define both the bulb models as different.

Both of the same capped bulbs use the same voltage alternating current, and they require no different wiring or plugging to mount. Thanks to the same Edison ring model.

But, the primary difference should distinguish them and give you a better and clearer idea.
