I won't link them because I don't want to get flagged for spam, but I really like the bulbs from cloudfree[dot]shop. They come pre-flashed with Tasmota and take <5 minutes to set up, then they can be controlled directly over wifi, or can easily be connected with HomeAssistant, etc. (Tasmota is open source local-only firmware, so there's no cloud or anything to worry about.) My only complaint is that they're not super duper bright. Other than that, I'm a big fan! Big fan of products from that site generally, and the guy behind it seems solid.
