Just what exactly is an A19?

Shaped like a snow cone, A19 bulbs are probably what you think of when someone says, "light bulb”. The A-Shape (Arbitrary) A19 LED light bulb, or general service bulb, is the shape we are all most familiar with. It is a shape so common that this is the universal symbol for light bulbs around the world! A19 bulbs typically come in outputs ranging from 20 watts up to 100 watts in their incandescent forms.

The A19 LED bulb has become the standard for household lighting in living rooms, bedrooms, and more. A19 bulbs were originally manufactured using incandescent technology but are now available as energy-efficient LED alternatives. Designed as a direct replacement for your existing incandescent light bulbs, the LED A19 consumes significantly less power and is the go-to option in lighting as incandescent technology goes by the wayside. And for good reason, too! LED light bulbs use up to 90% less energy than their incandescent equivalents, while producing the same lumen output. Great for your pocketbook, and great for the planet!

Did You Know?

The typical design of the incandescent A-shaped light bulb has not changed much since the prototype was fabricated by Thomas Edison. Since its inception, there have been state-of-the-art enhancements to improve its functionality. However, such developments as the tungsten filament and use of inert gases before the introduction of the LED, helped to shape the ways in which the light bulb has impacted the world.

What do you think of first when you imagine a light bulb? I can guess that it is most likely the standard A19, tear drop shaped bulb that has made its presence known around the world since the late 1800s. In addition to the A19 bulb, we are familiar with the A21, A23, and the A15 shapes. But what does the “A” in these types of bulbs mean? Great question, and I’m glad you asked! The “A” stands for arbitrary, and in the case of bulbs that means the shape was decided upon based on a random choice of its designer. The number that follows the “A” in these bulbs indicates the bulbs size when measured in 1/8” increments. For instance, a standard A19 bulb diameter measures at 19/8”, or when converted is 2.375”. The A21 bulb measures 21/8”, or 2.625” in diameter, but keep in mind that the A21 bulb is generally also slightly taller than the A19, which may prevent it from properly fitting in some fixtures. Be mindful of this when selecting a replacement bulb for your application. Also, keep in mind that A-shape bulbs are offered in A15 and A23 sizes.
