A Quick Comparison between A19 Bulb and A21 Bulb

Quoted in https://www.lohas-led.com/art/a19-vs-a21-bulb.html

Whenever you go over to the light bulb section at the hardware store, you may notice that there are two popular bulbs types - A19 & A21. However, most people do not know their differences, and may falsely assume A19 bulb and A21 bulb are interchangeable. To help out, we made this quick comparison guide here, giving you more details between these two bulbs. Let's take a look at the following contents.

What does "A19" or "A21" mean?
Which one is bigger? A19 bulb or A21 bulb?
What bases do they use?
Are A21 bulbs compatible with A19 lamp holders?
Are A19 light bulb and A21 light bulb for different uses?


What does "A19" or "A21" mean?

First of all, it is important to make clear what "A19" or "A21" means. The bulb names of A19 and A21 are actually describing their overall shape through a letter code (A) and their diameters at the widest point in eighths of an inch. The "A" shape bulb was one of the earliest bulb designs and has been a popular bulb type in home lighting. It has a pear shape and Edison screw base. Possessing a standard medium bulb base, A19 & A21 fit in most light fixtures such as table lamps, ceiling fans, wall lights and more. So they can apply for various purposes and occasions in every household. Generally, A21 light bulbs are less known and used in homes compared with their extremely popular counterpart - A19 bulb. 


Which one is bigger? A19 bulb or A21 bulb?

When we select or replace a new bulb, we need to know its dimension to make sure it will perfectly fit our lighting fixture. Normally, there is almost no difference in appearance between A21 and A19 bulbs except for their sizes. Let's see it together. A19 bulb is 2.375 inches in diameter(19/8=2.375) and 4.13 inches in height, while an A21 bulb is 2.625 inches(19/8=2.375) and 5 inches in height. So, as you can see, it is clear that A21 has a slightly longer neck and diameter than A19. Users may prefer bigger ones since the size of the light bulb will determine how much heat it can give off, and the more heat it gives off, the higher lumens it provides. In this sense, the A21 bulb works better in heat dissipation and light distribution.


What bases do they use?.

Save for the size difference, their bulb base is also an important element. The bulb base size helps you identify whether they can be screwed into your light fixture sockets to replace the old bulb. Coincidentally, A19 & A21 bulb both have an E26 light base so both can be connected to most standard light fixture sockets.


Are A21 lamps compatible in A19 lamp holders?

Now that they have the same E26 bulb base, you may think that they are interchangeable with each other, but not exactly like this. This is true to a certain level. While the bulb base size helps you identify whether they can be screwed into your light fixture sockets, the dimension determines if the bulb can fit in the lamp head. A19 bulb can be fitted to an A21 lamp holder, but not the other way round. There are two reasons. First, some A19 light fixtures or lamp holders are not designed to accommodate a larger bulb because of the space limitations. Second, A21 bulbs with higher wattage give off more heat that is closer to the lampshade, which increases the danger of fire. So A19 lamp holders may not match well with higher wattage A21 bulbs. Keep this in mind and choose the right bulb according to the size measurement of your lampshade.


Are A19 light bulb and A21 light bulb for different uses?

When it comes to the application, you have to consider several factors including their light distribution, your room size and type, electricity budget, and more. Both A19 and A21 bulb have a 360-degree beam angle, which offers an omnidirectional illumination for any room of varying sizes. Different room types require different brightness levels, so you should figure out the room type to avoid too dim or bright illumination. For instance, kitchens need to be brighter than the bedrooms. A21 bulbs have a higher lumen level and emit stronger lights as 100W incandescent bulbs do. But considering the cost, A21 bulbs also produce higher energy bills. In conclusion, if you don't need a strong and high-cost lighting, A19 led bulb would be an energy-efficient and wallet-friendly option.
Via the comparisons above in dimension, bulb base, and application, now you should understand the differences between A19 and A21. Keep these tips in mind and share with your friends!Want some led light bulbs?To buy on amazon:LOHASLED,To buy on LOHASLED official web

Things you should know about e26 base bulbs

Lighting terminology can be confusing if you're not in the industry. When you're looking to purchase a new bulb, you may have come across the term "E26" - but you might be unsure as to what it means. Light bulbs come in a variety of shapes and sizes,but E26 does not refer to the bulb's shape!



What is a E26 base bulb?

An E26 designation only refers to its base, or contact point with the lamp holder. A wide range of bulbs and smart lamps can use an E26 base despite having different shapes and sizes.
The letter "E" in E26 refers to Edison Screw, the most standard of lamp bases, while the numerical "26" refers to its diameter in millimeters (approximately 1 inch). E26 is also commonly referred to as a Medium Edison Screw (MES).
E26 is the size of most light bulbs used in the US and other countries that commonly use 120V AC. It's referred to as having a “medium” or “standard” base. (See E27 bulbs for Europe and 240V AC). Although previously they were most commonly used with incandescent lamps, fluorescent CFL lamps and LED lamps have also continued to adopt the E26 lamp base.
You can most instantly recognize an E26 bulb by looking at the bottom, or non-light emitting side of the bulb. If you see a metallic base with screw threads, approximately 1 inch in diameter, you most likely have an E26 bulb. Another way to be sure is to check the printing on the bulb - along with the wattage and brightness, manufacturers will usually print "E26" to ensure they are safely used with appropriate lamp holders.The number following the E indicates the size in mm of the external thread screw. Thus a E26 has a 26 mm base diameter.


Standards and Dimensions of E26

E26 standards are defined by the International Electrotechnical Commission (IEC) under standard 7004-21A-2. They specifically govern the exact dimensions to which the E26 lamp bases should be manufactured to.



Introduction to Edison screw bulbs

The screw comes in various size from E5 to E40, with the number behind the E represents the diameter size in millimeters. This E5 to E40 size are then deemed fitting, and each size are applied for different types, and sizes of light bulbs.
For example, E10 (10 mm) is commonly utilized in decorative lamps you often saw on Christmas trees, and some vehicle headlights and tail lights, as well as indicator lights on devices.
The E26 is called (Medium) Edison Screw, so it's abbreviated MES or simply ES. Also often called the one-inch Edison Screw.
It is the standard for most light bulbs, with the E26 being the standard for 120-volt bulbs (American usage).Being the standard for lighting usage, many low-voltage bulbs (12-volt,24-volt, etc.) are also designed to fit the E26 fitting.


The benefit of using E26 base bulbs

E26 bulbs are some of the most common lamp types, meaning that finding an appropriate lamp holder or fixture is typically quite straightforward. Additionally, installation is usually very straightforward, and requires no tools or assembly.
Edison Screw bases are some of the most secure ways to mount a bulb, due to the strength and rigidity of the screw threads. This makes them particularly suitable for locations where vibrations may be present. Additionally, a tight fit in the screw base ensures that moisture and debris are unlikely to enter the contact points, reducing the probability of electrical failures.


Example for your better understanding

The difference between A19 Bulb vs E26 Bulb
If you've seen what looks like the same type of light called both an A19 bulb and an E26 bulb, you might be wondering what the difference is.
Thing is, they might be the same thing.
A19 refers to the shape and size of the bulb itself. "A" stands for Arbitrary -- just the name of the shape that's familiar to most of us. "19" refers to the size -- in this case, 19/8" (or 2 3/8") across.
E26 refers to the type and size of the base -- the part that goes into the light socket. "E" refers to "Edison," which is the type of "screw in" style base people in the United States are most familiar with. 26 refers to 26 mm across. (This is also called a "medium" base.)
So the light bulb that most of us have used in our homes here in the States is an A19 bulb with an E26 base.
