Budget 1000+lm Flashlight with adjustable Beam and USB charging.

I think it’s a bit tricky. I believe to have read on an occasion that he was wrong about a technical issue. An output/time test would show what we (all) would like to see; minor gradual step-down is difficult to notice compared to a discrete step-down. But the Wuben is supposed to blink when it steps down, so dunno… Look at the run time data of the Niwalker MM20EB here: Review Niwalker MM20EB
It’s of course a different light, but there is no active step down present either; the light looses brightness gradually. This must also be the case with the Wuben to obtain the specified runtime.
