It’s a whole “different language,” if you’re gonna click to step up in brightness, then press+hold for off becomes the natural thing to do. And that might feel “logical” for a light where you press+hold for on as well, starting on moonlight.
I prefer press+hold to ramp up, then double-press+hold to ramp down. Single click—off, single click—on. But I like the press-hold for on/off for EDC keychain lights, which easily thwarts accidental activation. Some use double-click on, like RovyVon, and it’s a bit annoying.
LH351*B* is much smaller die area than D, and this light definitely uses the later. C is right in-between and pretty much equivalent to a 219C in die size and output, so there’s no way the smaller B model would hit 1000lm. B/C/D doesn’t denote generations or tint like it would for Nichia, it’s more like XP-E/XP-G/XM-L options from Cree for example.
Not the best tint bin of 351D I’ve had, but also far from the worst! Seems to be more toward the 5000K end on my SC21 as well.
Anduril would be nice indeed. Already have 2 and stepped mode works perfectly fine, so I’m out of the running for another one. But if they can get more usable ramping I’m all for it!
Btw, seems these are a mixed bag when it comes to unscrewing the bezel. 1 could be unscrewed relatively easy with bare hands (2700K), but the other one was impossible, even with thick latex gloves (4000K). Glue?
