If I insist on only using existing ceiling light fittings—so I need bulbs with (as I’m in the UK) standard bayonet mounts and form factor similar to that of traditional incandescent bulbs—are there any good options? I’m having trouble finding anything with both decent brightness and good CRI, but maybe I’m looking for the wrong thing (I’ve been assuming LED is best these days) or in the wrong places.
