One thing you not know about LED light bulbs||LOHAS LED

We should know something about the light bulb base types and light bulb types.
In daily life, we can see the letter "E" and "A" on all the light bulbs, for instance, e26 led bulbs and a15 light bulbs. Do you know what does it mean?
Let me show you more detail.

The A-series light bulb is the "classic" glass light bulb shape that has been the most commonly used type for general lighting service (GLS) applications since the early 20th century. The "A" refers to the overall shape of the bulb, It has a pear-like shape and is typically fitted to either an Edison screw or a bayonet cap base. The two digits after the letter refer to the bulb's diameter at its widest point and are measured in eighths of an inch. An A15 bulb, therefore, has a diameter of 15 divided by 8 inches, or approximately 1.9 inches.

Such as E26/E27, the letter E before a number indicates it's an Edison bulb. The Edison screw fitting is a system of screw mounts used for light bulbs developed by Thomas Edison in 1909.
E26 is the size of most light bulbs used in the U.S. It's referred to as having a"medium” or "standard" base.
Edison Screw:
The term E26 refers to a light bulb's cap or base - the bulb component that allows for both electrical and mechanical contact. The letter "E" in E26 refers to Edison Screw, the most standard of lamp bases, while the numerical "26" refers to its diameter in millimeters (approximately 1 inch).
