After a power outage it switched to dusk-to-dawn mode and won't
budge.

A power outage destroyed one of mine, luckily ($50 lights) it was one of
Home Depot's that had a life time warranty and I still had the receipt.
It's the rapid on and off during outages that gets them, I had two on the
same circuit and it just got the one. RM~
