A19 vs. E26
A19 is a reference to the bulb’s shape and size. The letter “A” stands for “Arbitrary,” which is the shape’s name, as most of us know it. The number “19” alludes to the diameter of the piece, which is 19/8″ (or 2 3/8″).
The size and shape of the base — the component that fits into the light socket — are indicated by the designation “E26.”
When you hear “Edison,” you’re thinking of the screw-in style base that most Americans are used to. 26 mm is the diameter of the piece.
As a result, the most common light bulb in American households is an A19, including an E26 base.
Because you can’t simply call for this one and receive the bulb you want, knowing the form and base of a light bulb is essential.
Most American A19 bulbs get an E26 base. However, this isn’t always true. There are a variety of bulb shapes with E26 bases; thus, just requesting an E26 bulb will not suffice.
What Is The Difference Between A19 and E26 Bulb?
A19 bulb Refers to the shape of the bulb. It has a round shape with a tightly folded edge and looks like the number 5.
E26 bulb Refers to the base of the bulb. E stands for Edison, which is where it was invented. It has an oval-shaped base with rounded edges and looks like the number 8.
The A19 and E26 bulbs are two of the most popular types of light bulbs on the market. So, what are the main differences between these two bulbs? Here are some other key differences between the two:
| A19 bulb | E26 bulb |
| Refers to the shape of the bulb | Refers to the base of the bulb |
| “A” means bulb width | “E” means screw diameter |
| 100-110 mm | 26 mm |
Can I use an A19 bulb instead E26 bulb?
Yes, you could use an A19 bulb for the same wattage as an E26 bulb. The A19 is a slightly different shape than the E26 to accommodate larger bulbs, so it should fit in your sockets without any trouble.
Brightness (Lumens/ Watts) A19 Lamp Have?
A19 lamps typically emit around 1,100 lumens maximum. A single A19 lamp will provide enough light to read or work on your computer for about an hour. Some of the best lamps will be between 600 and 700 lumens.
A19 Bulb Color Temperature (CCT)
Color temperature is the specific color of a light source and its corresponding visual appearance. Color temperature is a characteristic of visible light that influences human psychological, physical, and biological responses.
Electromagnetic radiation with a wavelength from approximately 700 to 400 nm, or equivalently from 2700K to 3000K in the traditional non-metric Kelvin scale (as used in astronomy), can be seen as colors from red through yellow to white.
What is an A19 BULB?
Bulb head size is measured in diameters, but the most common head size is an A19. The A in the nomenclature refers to a traditional tungsten light bulb and 19 refers to the diameter of the bulb in eighths of an inch.
Jslinter LED Edison Bulbs
The Jslinter LED Edison Bulbs are available in many colors that complement any decor or style because they have powerful light output without producing heat or UV rays. They’re made using high-quality, energy-efficient parts that do not produce heat or UV rays.
They’re long-lasting, requiring only a fraction of the energy consumption compared to regular bulbs to achieve the same illumination level.
You can use them in your lamps and overhead lighting without them providing enough light and become dangerous and unnecessarily costly.
The color temperature of these LED Edison Bulbs is between 2,700 K and 3,000 K, and they have a lifespan of up to 25,000 hours.
Philips Hue E26 LED Smart Bulb
Philips Hue is a trademark for an intelligent lighting system launched in 2012 by Philips, the Netherlands-based electronics company.
It uses an Android or iOS app to produce lights that can change colors and follow scenes based on user actions.
The light bulbs used in Hue use LEDs, and as such, they can last up to 25 years before they will need replacing them with new ones.
The light distribution of the A19 bulb
A19 bulbs have no built-in reflectors, allowing them to shine light in all directions. An incandescent bulb’s filament emits all of its light in one direction: outward.
Most A19 LED bulbs produce light at a broad angle to simulate the light distribution of incandescent light.
However, some achieve this greater than others. A19 LED filament bulbs were created to mimic the light dispersion of an incandescent filament as closely as possible. These bulbs use LED filament technology to produce light like that of a classic filament bulb.
Dimensions of an A19 bulb
The diameter of a light bulb determines how much light it can produce. The bigger the diameter, the lighter it can produce because more of the filament (or, in most cases today: LEDs) will emit light.
- 40W Type 211: length 112.7 mm, width 69.5 mm
- 100W: length 112.7 mm, width 69.5 mm
- 50W Type 206: length 100 mm, diameter 68.0 mm
- 40W Type 210: length of 108 mm and a diameter of 69.0 mm.
- 75W: length 112.7 mm, diameter 69.5 mm
- 50W Type 211 has a length of 112.7 mm and a diameter of 69.5 mm.
- 60W: length 112.7 mm, diameter 69.5 mm
If an A19 bulb is within 112.7 mm in length and 69.5 mm in diameter, it is generally regarded as within its dimensional standards.
A19 bulbs always use E26, but not vice versa
The A19 bulb always uses the E26 socket, but not vice versa. This is because of a difference in thread size.
The A19 connection is 1/2″ in diameter and the E25 connection is 3/4″, which means that you can’t insert two of one type of light bulb into the same socket.
Another name for the connector is also 1/2″ to E25 and 3/4″ to E26, but this type of bulb has a different size gauge, and it’s easier to confuse them.
What is the difference between A19 and A60?
At two and three-eighths of an inch in diameter, the A19 bulb has a diameter of four and three-eighth inches.
The metric variant of A19, and A60, is the same thing. The difference is its metric. So, it has a diameter of sixty millimeters, two and seven-eighths of an inch.
A19 bulbs have been around for a while. The stores sell them and the price is right, so that is what most consumers buy.
However, the government has decided to classify LEDs as A19. It’s not as though you can’t use an A60 in an A19 lamp holder, they are just sold differently in some stores like Home Depot.
About E26 Bulb
Regarding the bulb’s cap or base, E26 refers to its electrical and mechanical components. “E” stands for Edison Screw, its most common kind of lamp base, and “26” is the diameter in millimeters of this base.
In the olden days, Edison screw base bulbs were a standard product in electric light bulbs. The bulb’s cap is different from the American standard E10 (in diameter). A number of years later, the E14 was designed and this kind has a larger diameter, 14 mm.
In Europe and America, those two kinds of Edison screw bases have been widely accepted by the common public, however, in the South East Asia region, there is no such thing as E14 or E26 so far.
Luxrite A19 LED Light Bulbs
LEDs are the latest in lighting technology and are an excellent way to save money without sacrificing quality.
They provide comparable brightness but use less electricity than a traditional incandescent bulb. The lower operating cost of LEDs, combined with the long lifespan, make them an excellent choice for any home or business.
Traditional lighting uses a lot of energy. Incandescent bulbs can consume up to 90% of the energy it uses to produce light.
LEDs only consume 10% as much energy. This means you will save money and do your part to help save the environment.
Vintage Incandescent Edison Light
We are on the verge of a revolutionary change in technology. The lightbulb we know and love, the one that lit up our world for a century, has been cast aside in favor of LED bulbs.
They last longer, use less electricity than incandescent bulbs and can be dimmed and turned off at any time.
But they are not as warm, not as bright, and don’t give off the nostalgic glow of the lightbulb we grew up with.
We have resisted the change so far, or at least tried to make it work by saying no to LED bulbs, preferring instead incandescent bulbs that we switched off in the daytime or installed dimmers. But now those bulbs are fading away too, almost as quickly as they came on.
Today, President Donald Trump started phasing out conventional lightbulbs in America.
Is E26 a standard light bulb base?
Yes, E26 is a standard light bulb base. It was designed for incandescent light bulbs because these lights require the Edison-style base due to their high power requirements and great heat output.
An E26 socket will hold up to a 132-watt bulb, but it can also support a CFL or LED lamp with a lower wattage. This socket is typically used in our homes and buildings, such as schools, offices, and hospitals.
E26 bulb wattage
Different light bulbs are best suited for different purposes. In general, dimmer light drains less electricity than brighter lights.
A dimmer bulb with an E26 thread base puts out 800 lumens at 8.7 watts (equivalent to 60 watts). A standard or decorative A19 bulb, also with an E26 thread base, puts out 1600 lumens at 16 watts (equivalent to 100 watts).
What light bulb fits in E26?
A19 and A21 light bulbs fit in E26 light fixtures. The only difference between these two products is the shape of the bulb’s base.
You’ll find that an A19 bulb has a narrower base than an A21 bulb. This narrow-base metering to a wider bottom is what enables it to fit into a range of lamp bases, including E26s.
The same goes for an E26 which fits differently into different lamps with different shapes and sizes.
A23 light bulbs will fit into an E26 and similarly, an E26 will fit into an A23 light fixture. Because of the product’s round base, it is also known as a medium (E26) Edison screw base.
Is E26 the same as st19?
Not all E26 lights have A19 bases and vice versa. A19 light bulbs must have an E26 base because of the rules that control their size and design.
All A19 bulbs have an E26 base, in other words. Variations on the light bulb specification allow E26 bases to be used in A19 sockets.
Also, some lamps have a text (D1) marking on their base, which is a different specification and must have an E26 base.
If you have some E26 lamp without a D1 marking on its base and an A19 socket with a “standard” sized screw, then the only safe possibility is that your bulb may be an A19-E26 adapter with an E26 base.
What is the difference between E26 E27 and A19?
The socket base size E27 (or E26 in the United States) is sometimes known as a medium base. The standard form for an indoor light bulb is A19. They also provide a BR30 bulb with an E26 medium base that fits into typical ceiling can fixtures.
The A19 is a larger bulb, with a glass diameter of 4 1/4 inches, it has about 2 inches of air space for the filament to get hot and emit light.
The E26 is smaller and has glass that is only 3 1/8 inches in diameter. That leaves less room for the hot air to get out, so it’s bluer in color.
How bright is an E26 LED bulb?
There’s at least one way to tell how bright something is: measure the amount of light in lumens. Lumens are a way to describe the quantity of light; a beam of 1000 lumens (about as much light from a typical desk lamp) lets you read a book as easily as if you were in daylight.
A 100-watt incandescent lamp has about 1600 lumens, so it’s not surprising that an LED bulb that uses only 15 watts can’t be quite as bright.
Is E26 a regular light bulb?
Yes, it’s a regular light bulb. E26 is a type of light bulb that has a very long filament made up of many thin wires wrapped together around the metal core.
So that when it heats up the filament conducts heat well enough to glow yellow-orange in daylight conditions but minimizes consumption at night by limiting current into unused parts of the metal core. And thus conducting heat out through the ends of each wire instead.
FAQs
1. Is A19 a standard bulb?
Yes, A19 is a standard bulb. It means that the bulb has a base of 19mm in diameter, and its light-emitting diodes are spaced 19.2mm apart from each other.
It was originally used for general lighting in homes but is now mostly used for decorative lighting purposes instead.
2. What is an A19 bulb used for?
They are often used for LED and CFL to provide light in areas where incandescent bulbs are not recommended, such as stairwells and the inside of buildings.
As the A19 bulb is more efficient than an incandescent bulb it can save up to 75% on energy costs when compared to similar lighting fixtures.
The temperatures produced by these bulbs also allow for greater control over room temperature and heating requirements.
3. What is an A19 bulb equivalent to?
The bulb that is the equivalent to an A19 bulb is a 2-3/8″ diameter or 4-1/2″ diameter bulb. An A19 light can be replaced with the typical incandescent bulbs that are commonly used for general lighting. These incandescent bulbs are typically found in table lamps and ceiling lights.
