Buyer’s Guide: More About A19 vs A20 Types, How to Choose the Right One
Here we’ve prepared a short fact-check about A19 and A20 bulbs to help you choose between the two.
A19 Bulb: Everything You Need to Know
- High-quality materials
- High luminosity
- Lifespan: 25,000 hours
A19 means:
- “A” describes the shape of such a bulb, which is classic – an upside-down pear. It’s been given the letter “A” due to being the first and only shape back in the day;
- Digits explain the diameter of the widest part of this bulb. It’s calculated in 8s of an inch for convenience. 19” by 8” equals about 2.4”, but it’s easier to remember A19 rather than A2.4, right?
The A19’s length is about 3.9”-4.3”, these sizes are controlled and checked by the ANSI C79.1 standard in North American countries. The same document specifies that A19 bulbs should always have an E26 base. But not all E26 bulbs have A19 shape.
A21 Bulb: Everything You Need to Know
- FCC, RoHS, UL certified
- Powerful
- Energy Saving
- “A” means the upside-down pear shape of the bulb;
- Digits mean its diameter – 21” by 8” equals about 2.6”.
A21 lamps are rarely used compared to A19-type bulbs as they are more powerful. A21s are great to use in settings where you need more light and can use more energy. This type isn’t always suitable for homes not only because it’s more powerful, but also because it uses more electricity.
In Europe and other countries that use metric system, these bulbs are referred to as A67, meaning their diameter is 67 millimeters.
All A21 bulbs have E26 base size. So, they are interchangeable with all E26 lamps that aren’t smaller in size.
You can change A21 for A19 but changing A19 to A21 might be trickier.
If your fixture is for smaller bulbs, fitting a larger one may be impossible or it may ruin the look. A19 lamp holders may not adapt to the current that A21 needs, creating even a bigger issue.
When changing any other proper-sized lamp for A21, its wattage, luminosity, CRI, and light temperature should be considered.
How to Choose the Equivalent to Your Incandescent Bulb?
As to the brightness and wattage, you can always find them on the package. LED lamps use about 1/10th of energy incandescent ones use. A 6W lamp, for example, might have “60W equivalent” specified in its description. Such marks should help people choose the same bulb they’ve been using but more efficient.
Same situation with lumens and color temperature. A19 lamps can be 450lm or 1000lm, while A21 lamps are usually more powerful (2,000-2,500lm and more) since they are bigger. There’s more space in the bulb and more material to dissipate heat through effectively, therefore it allows more power.
Be Careful About the Choice of a Bulb
There are so many things to pay attention to when choosing a light bulb. First of all, make sure it’s an LED one. Such lamps are eco-friendly, powerful, and energy-saving. They don’t heat up a lot and are much rarely a fire hazard.
Then, make sure you remember what type of base and bulb you need. Correct measurements will ensure it fits perfectly in your fixture. If choosing between A19 and A21 lamps, we recommend the first for houses and apartments. They are less powerful, less bright, a bit smaller. Even if your house is large, it’s better to design several less bright fixtures that will illuminate it with a soft or warm white glow. Cold tones and much power are more suitable for outside illumination and places where you need extra precision of sight like schools, hospitals, and more.
