How long will an EcoFlow DELTA 2 Max run incandescent Christmas tree lights (500 bulbs)?
About 6.8 hours — 6 h 50 min typically, from 6 h 26 min in the worst case to 7 h 14 min at best. That assumes incandescent Christmas tree lights (500 bulbs) pulling 204 W continuously, plus the station's 14 W AC mains socket overhead — 218 W in total out of 1,488 usable watt-hours.
The old bulbs draw about six times what LEDs do for the same tree, and run hot.
