How long will a Goal Zero Yeti 700 run LED Christmas tree lights (500 bulbs)?
About 11 hours — 11 h 11 min typically, from 10 h 31 min in the worst case to 11 h 50 min at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 9 W AC mains socket overhead — 44 W in total out of 492 usable watt-hours.
About a sixth of the same tree in old incandescent bulbs, and cool enough to touch.
