Which one to buy

Pick by socket: the E26 for standard lamps and fixtures, the E12 for candelabra sockets. I haven't run either; the notes come from IKEA's US pages, the CSA listings and Matter Survey.

I haven't run any of these; the picks are based on the spec sheets and what other Home Assistant users report.
