Again, haven't had time to parse the logs (silly day job) but posting these for @Pmccraw to compare/contrast as they build their case notes:
This is the rule that was working:


My other LIFX outdoor floods still work fine! I also noted that @Pmccraw is having this with another brand. My guess is that HA changed something because it started immediately after deployment of 11.0 (and I seem to recall some notes around dimming or some such but I just haven't been able to track it back).
Here's a quick grab from the log file, best I can do atm.
