About 13 hours — 12 h 34 min typically, from 11 h 50 min in the worst case to 13 h 19 min at best. That assumes incandescent Christmas tree lights (500 bulbs) pulling 204 W continuously, plus the station's 18 W AC mains socket overhead — 222 W in total out of 2,791 usable watt-hours.
The old bulbs draw about six times what LEDs do for the same tree, and run hot.
