Nice looking light. It’s impressive how small they were able to make it - really telling next to the A01.
That said, the output/runtime seems disappointing. Roughly 150 lumens for 40 minutes, followed by a quick drop? One of my most recent purchases, the Jetbeam u, does around 105 lumens for at least 55 minutes before any noticeable drop (see Budda’s testing). And that’s with a AAA… 1/2 to 1/3 the mAh of a AA. Unless I’m reading it wrong, that seems terribly inefficient.
