B22 Bayonet Cap Globes, the Standard New Zealand Connection Across Every Form

The B22 standard bayonet cap globe is found in the majority of ceiling lights, floor lamps, and table lamps across New Zealand homes. Dulora's B22 globe range covers GLS A60 globes, candle globes, fancy round globes, filament globes, and specialty forms across the full colour temperature range from Ultra Warm 2000K to Natural White 4000K, with CRI 90 to 97+ across the 240V dimmable range.

Because B22 appears in so many fittings across a typical New Zealand home, the quality of globe in these fittings makes the biggest cumulative difference to how the house feels. Upgrading every B22 fitting from a standard CRI 80 globe to CRI 90 to 97+ changes the quality of light in every room at once.

All dimmable models work smoothly with the DimEzy range LED Light Dimmers. For the E27 Edison screw equivalent, see E27 Globes. For browsing by globe shape, see GLS Dimmable, Candle Globes, and Edison Filament.

B22 Globes: The Standard Bayonet Cap That Powers Most New Zealand Homes

What does B22 stand for and is it the same as BC?

B22 stands for bayonet cap with a 22mm diameter base. BC, standard bayonet cap, and B22 all refer to the same fitting: the push-and-turn connection that is the standard for ceiling roses, pendant lights, floor lamps, and table lamps across New Zealand homes, particularly in older properties.

The bayonet connection is a British-heritage standard and remains one of the two most common bases in New Zealand alongside E27. If your fitting uses a push-and-turn connection rather than a screw-in one, it is a bayonet cap. If the globe is the larger of the two bayonet sizes, it is B22.

Which B22 globe shape suits each room?

GLS A60 is the default for any fitting where the globe is hidden behind a shade: ceiling pendants, floor lamps, table lamps. It provides the best combination of lumen output and versatility and covers the widest range of rooms.

Filament (ST64, G95, G125) suits exposed-globe fittings where the globe's form and glow are visible: open pendants, cage fittings, and feature floor lamps. Choose the size based on the scale of the fitting.

Candle (C35) in B22 suits larger chandeliers and bayonet-based decorative fittings. Fancy round (G45) in B22 suits bedside lamps and compact ceiling fittings.

For most B22 replacement decisions, GLS A60 is the starting point. Move to filament, candle, or fancy round only when the fitting is visible or the aesthetic calls for a specific globe form.

Is B22 or E27 more common in New Zealand homes?

Both are common. B22 is more prevalent in older New Zealand homes and in fittings with British-heritage electrical connections: many ceiling roses and older pendant fittings use bayonet cap. E27 is more common in newer builds and modern fittings, and is the default for most imported luminaires.

In practice, many New Zealand homes have a mix of both. Check the fitting rather than assuming. If the globe pushes and turns, it is bayonet (B22 or B15). If the globe screws in, it is Edison screw (E27 or E14).
