All except their new wifi connected ones... called Wiz.. watch out for those, much more affordable but really crappy app/setup situation.

Wiz bulbs use ESP-NOW (so that the Wiz remote can communicate with them). They also have an ESP-WROOM-02 inside (a package integrating an ESP-8266EX).

The fact that they use ESP-NOW means they can be controlled (theoretically) by any ESP* that has ESP-NOW support. So far, folks have only managed to go the other way—to intercept remote key presses [0]—but I imagine it won’t be long before they suss out control of the bulbs.

Also the wiz bulbs have one feature that most others don't have: they get their last state back after a power outage. If there's one thing you don't want, it's a full bright room after a brownout in the middle of the night!

All Hue lights have this option. You can select different power-on behaviours. "Power loss recovery" is the setting you are describing. It stays off if it was off, and turns back on if it was on.

The default is "Warm white, full brightness", probably mostly to avoid confused people sending back bulbs because they flipped the switch ON and the bulb remained dark. Since traditionally that meant a failed bulb.

Those WiZ bulbs have actually been pretty reliable for me in the few years I’ve had them. Pretty early on I set them up to be controlled by Home Assistant [1], and they are on par with my other Hue devices in terms of performance (maybe not a 100% match in brightness, but close enough). Definitely worth their much cheaper price to me.
