I just noticed that there’s a 3-pack of Philips Hue White bulbs on-sale on Amazon right now and this seems to be a pretty good price for the white dimmable (not tunable to other colors of white) models, compared to the Osram Lightify which have been in the $14-15 range recently… Of course, you probably want a Hue hub for these unless you have one of the remotes that can break/re-pair the connection, and your ST hub ZigBee frequency is on the right one (there’s a few threads here that I remember reading when I first got some Hue bulbs that explains this, but mine are on the Hue Hub so I don’t know what the current situation is)…
