E27 vs. B22 bases — What's the difference?

E27 and B22 refer to the base type of a light bulb. Check your lamp's specifications to determine which base type you need. You don't want to get this wrong!

The "E" in E27 refers to the Edison screw base while the "27" means that the base diameter is 27mm. The E27 is a screw in fit. This base is the most common in Australia.

B22 denotes a "Bayonet" base with 22mm diameter, which is a simple push and twist to fit.

Currently we do not offer E14 smart bulbs.
