Thanks! Yeah, it’ll run when charging, thanks to using a
battery from the TP-Link Tapo cameras, though you need to set it on its side to charge it, so that would be awkward-ish. But the lamp runs for over a month using it for a bit every evening in its brightest mode. We’ve had the first two of them in use in the house for over six months now, and neither has needed to be recharged yet (it’s a 6700 mAh battery)
Next one off the line will have a side-charge, probably.
