A19 Bulbs: The Pear-Shaped Pioneers of Home Lighting

Shape: The “A” stands for “arbitrary” but means pear-shaped. Picture a classic light bulb – that’s an A19!
Size: The “19” refers to the width. It’s 19/8 inches (about 60mm) at the widest part.
Versatility: These bulbs fit most lamps and fixtures, making them super popular for general home lighting.
Options: You can find A19 bulbs in various types – incandescent, LED, CFL, and more.

What is an E26 Bulb?

E26 Bases: The Unsung Heroes of Bulb Compatibility

E26 bases are the standard screw-in part of most American household bulbs. Here’s why they’re so important:

Meaning: “E” stands for Edison screw, named after Thomas Edison. “26” means the base is 26 millimeters wide.
Compatibility: This standardized size ensures most bulbs fit most fixtures in your home.
Versatility: Many bulb shapes (not just A19) can have an E26 base, increasing your lighting options.
Reliability: The design has stood the test of time, remaining largely unchanged for decades.
Unsung role: While we often focus on bulb types or wattage, the E26 base quietly ensures everything works together smoothly.

Is A19 the Same As E26

No, A19 and E26 are not the same, but they often go hand in hand. Let’s break it down:

A19 refers to the bulb’s shape and size:
- “A” means arbitrary, but it’s a pear shape.
- “19” indicates it’s 19/8 inches (about 60mm) at its widest.
E26 describes the base type:
- “E” stands for Edison screw.
- “26” means the base is 26mm wide.
Most A19 bulbs you’ll find have an E26 base.
But not all E26 bulbs are A19 shaped. You can find candle-shaped or globe-shaped bulbs with E26 bases too.
When shopping, look for both A19 and E26 to ensure the perfect fit.
