I will try to see if it's passive charging too. If it is, then the runtime to lumens usage may not be the priority for concern.

Idk why the manufacturers don't create a way to connect it to a computer or smartphone via USB to switch around button functions, omit or add light display options ie: flashing sequence, multi steady toggles only with different preprogrammed brightness settings.
the Xmas lights these days can do it...
