How long will an EcoFlow DELTA 3 Plus run incandescent Christmas tree lights (500 bulbs)?
About 3.5 hours — 3 h 28 min typically, from 3 h 16 min in the worst case to 3 h 40 min at best. That assumes incandescent Christmas tree lights (500 bulbs) pulling 204 W continuously, plus the station's 11 W AC mains socket overhead — 215 W in total out of 744 usable watt-hours.
The old bulbs draw about six times what LEDs do for the same tree, and run hot.

- Start-up: the incandescent Christmas tree lights (500 bulbs) asks for 204 W at switch-on against this station's 3,600 W peak — comfortable.
