Modern LED light bulbs come in various shapes and sizes, and most homeowners find them quite confusing. There are just so many options to choose from. Eight different light bulbs are typically found in most households, and these bulbs are used in various fixtures. They also come with various requirements when it comes to the size, shape, and the way the bulb projects light. As a result, finding the right bulb has become quite tricky.
What are Light Bulb Codes?
It is important to understand the common household light bulbs as well as their shapes, sizes, and styles especially if you are updating incandescent fixtures into energy-efficient ones. Light bulbs have identifying characteristics, which make them unique from other bulbs. These characteristics are represented by a letter or series of letters and a number, which are known as light bulb codes.
The letter or letters indicate the shape or special feature of the bulb, like its reflector. The number in the code indicates its size in millimeters or eights of an inch. You need to know these codes, so you would know which bulb will fit into your fixture. You would also know if it’s the right shape.
What are A19 Light Bulbs?
Standard Arbitrary bulbs are the most common and widely used bulbs when it comes to household lighting. These are what everyone first thinks of when they think of “light bulbs.” They work well for a variety of household applications including ceiling, vanity, kitchen, closet, porch lights, and so on. A stands for arbitrary, and the number represents the bulb’s diameter in one-eighth of an inch.
A19 measures 2-3/8 diameter. This is the most common size and shape, and you will often find it in most homes. They are often used in lamps, sconce fixtures, hallways lights, ceiling fans, and more. The shape of the bulb hasn’t changed since Edison first produced it in 1879.
