Okay, so you’re confirming that the As and Bs have essentially the same UI.
The reason I liked the A for the gf is threefold.
First, she doesn’t see a need for true firefly mode (you really gotta be in total blackness and be fully-dark-adapted for it to not be completely useless), so it’s a waste to put it into rotation unless it’s actually of value to you.
Second, it’s kinda dangerous, that unless you look at the LED (vs shining at a table, wall, even opposing hand, in any kind of light), you’d think it’s off when it’s actually still on.
Third, “turbo” (ie, just plain high) is quite useful, and doesn’t overheat the light any. So it’s not so great to “hide” it with a doubleclick.
The older A is much better for her because she has L/M/H right there at her fingertips, in rotation, no special clicking necessary.
Now, for me, yeah, I do use firefly, and quite often, so I’m okay with having it in rotation, ie, only F/L/M. But also for me, being that H is quite useful, too, it’s nice to be able to doubleclick to get it whether on or off.
So it depends on the “audience” which UI is better, but it was quite nice to have the choice between A or B in the same light.
Me, I’d be okay with 5/30/150 or a similar range (whether alkaleaks or 14500; more important about the ratio). So moonlight instead of firefly, and low being not so huge a jump. Or maybe 2/10/50/150, something like that, for more “gears”.
Alkaleaks do just that, leak. And they’ll ruin your light the first chance they get. They’re hateful little things.
If you don’t want to spring for eneloops, hie thyself to Ikea and get their LADDA cells. Same innards, just rewrapped under the Ikea banner. ’Though I’m surprised they don’t just give you eneloops and wrappers and make you rewrap them yourself.
