A19

The familiar general-service bulb format used throughout homes and commercial interiors.

Available Bulb Base

The familiar general-service bulb format used throughout homes and commercial interiors.

How to identify A19

A means arbitrary—the classic pear-like lamp shape. The number 19 indicates a nominal diameter of 19 eighths of an inch, approximately 2⅜ inches.

Common applications

Table lamps, floor lamps, pendants, ceiling fixtures, closets and general ambient lighting.

Technologies and base options

A19 lamps exist in LED, incandescent and halogen forms with different voltages, outputs, colour temperatures, finishes and dimming characteristics.

Technologies represented in this library: LED, Incandescent, Halogen.

Available base types: E26, E27, B22.

Typical market availability

Technology Common wattage range Typical lumen range Common colour temperatures Common voltage options
LED 4.5–17 W 450–1600 lm 2200K, 2700K, 3000K, 3500K, 4000K, 5000K, 6500K 120V; 220–240V; universal-voltage options
INCANDESCENT 25–100 W 250–1600 lm Approximately 2700K 120V; 220–240V
HALOGEN 29–72 W 370–1490 lm Approximately 2700K–3000K 120V; 220–240V

These are representative market ranges, not guaranteed limits. Availability varies by manufacturer, voltage, base, beam, region and product generation.

How to select the correct lamp

Choose by base and voltage first, then compare lumens, colour temperature, dimming, enclosure suitability and damp- or wet-location ratings.

Compatibility and safety

Wattage does not measure brightness across different technologies. Compare lumens when replacing incandescent or halogen lamps with LED.

Important: The library describes a lamp format, not a particular product. A shared shape does not guarantee matching voltage, base, dimensions, light distribution or control-gear requirements. Confirm the fixture label and product datasheet, or ask a Bulb World lighting specialist.

Replacement Notes

Choose by base and voltage first, then compare lumens, colour temperature, dimming, enclosure suitability and damp- or wet-location ratings.

Capability Warning

Wattage does not measure brightness across different technologies. Compare lumens when replacing incandescent or halogen lamps with LED.
