As far as I know, they will reconnect after power and/or internet failure. I have had 2 bulbs for over 6 months now and I have never had them drop off and I know we have had power failures since then.
You do have to use the LIFX app, which was not a problem. Then you run the built-in HE app LIFX integration which is also painless.
I got them because they were recommended by @bcopeland as his favorite bulbs....My Favorite Devices (Updated)
The LIFX color A19 are $32 now on Amazon.
