- General home lighting
- Office spaces
- Retail environments
- Hospitality settings
The Relationship Between E26 and A19
E26 and A19 often go hand in hand. Many A19 bulbs use E26 bases. However, they are not the same thing. Let’s explore their relationship.
How E26 and A19 Work Together
E26 bases can support various bulb shapes. A19 is just one of them. Most A19 bulbs in the US have E26 bases. This combination is common but not exclusive.
Key Differences Between E26 and A19
Here’s a table highlighting the main differences:
| Aspect | E26 | A19 |
| Refers to | Base type | Bulb shape and size |
| Measurement | 26mm diameter base | 2.375 inches diameter bulb |
| Function | How the bulb connects | Overall bulb appearance |
| Interchangeability | Works with various shapes | Usually uses E26 base, but not always |
Common Misconceptions
Many people confuse E26 and A19. They think they’re interchangeable terms. This is not correct. E26 is about the base. A19 is about the bulb’s shape.
Choosing the Right Bulb
Selecting the appropriate bulb involves considering both E26 and A19. Here are some factors to keep in mind:
Compatibility Considerations
Check your fixture’s requirements. Ensure the base type matches. Verify if the bulb shape fits the fixture. Consider any size limitations.
Performance Factors
Think about your lighting needs:
- Brightness (lumens)
- Color temperature
- Energy efficiency
- Dimmability
Cost and Longevity
Compare initial costs with long-term savings. Consider the lifespan of different bulb types. Factor in energy consumption over time.
