Incandescent Light Bulbs

good bye incandescent light bulbs

Incandescent means to emit light as a result of being heated, and that is exactly how an incandescent light bulb works. It gives off light when the filament is heated by the current of electricity that powers the fixture it is installed in. There are several different types of incandescent bulbs, ranging in shape from the standard A-shape, what is typically thought of when light bulbs are mentioned, to decorative flame tipped shapes, and even globe shaped bulbs that light up the marquee at your favorite movie theater. Incandescent light bulbs have benefited mankind for more than a century, and have paved the way for new, and more efficient lighting technologies to emerge. Until the day that incandescent bulbs are no longer in production, however, GoodBulb is the place to find the right incandescent bulb for your needs!

Light Bulb Moments

What is an A-shaped light bulb?

What do you think of first when you imagine a light bulb? I can guess that it is most likely the standard A19, teardrop-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, as well. 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, we take the definition of that to mean the shape was decided upon based on random choice of its designer. The number that follows the “A” in these bulbs indicates the bulb’s 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. Keep in mind, also, that A-shape bulbs are offered in A15 and A23 sizes, too.
