How long will a Goal Zero Yeti 1000 run incandescent Christmas tree lights (500 bulbs)?
About 3.4 hours — 3 h 22 min typically, from 3 h 11 min in the worst case to 3 h 34 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 725 usable watt-hours.
The old bulbs draw about six times what LEDs do for the same tree, and run hot.

- To keep it going for a full 24 hours you would need about 7,100 Wh of rated capacity — 7.1× this station.
- 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.
