How long will a Bluetti EB3A run incandescent Christmas tree lights (500 bulbs)?
About an hour — 55 min typically, from 52 min in the worst case to 58 min at best. That assumes incandescent Christmas tree lights (500 bulbs) pulling 204 W continuously, plus the station's 9 W AC mains socket overhead — 213 W in total out of 195 usable watt-hours.
The old bulbs draw about six times what LEDs do for the same tree, and run hot.
