How long will an EcoFlow RIVER 2 Pro run incandescent Christmas tree lights (500 bulbs)?
About 2.6 hours — 2 h 37 min typically, from 2 h 27 min in the worst case to 2 h 46 min at best. That assumes incandescent Christmas tree lights (500 bulbs) pulling 204 W continuously, plus the station's 10 W AC mains socket overhead — 214 W in total out of 558 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 1,600 W peak — comfortable.
