I stocked up on those Glaree AAA lights that were at Amazon for cheap. I’m not a fan of AAAs, but for sub-hour runtime in case of an emergency (like you say, heading to the can at night), sure, a dedicated real flashlight is better than using your phone as a “flashlight”.
That F3 looks like a nice light, and if the build quality is as good for that as it is for the F1, well, I’d consider it. Not for 20bux, but for a GB flash-sale or something, yeah. Considering that A01s and Boneys and the like (with Nichias!) were about half that…
While I love the Nichia, the BLF-348 had (to me, ymmv) a crappy build quality. Press-fit switch, hairlike threads that strip when you look at ’em wrong, I wasn’t thrilled at all. If the F3 is sturdier, and with the larger diameter it certainly looks so (and I love that styling!), it’d definitely be worth a higher price than the ’348.
But, alas, not really to me, because like I said, I’m not a fan of AAA lights to begin with, and the Glaree was at about the highest price-point I’d tolerate for a non-Nichia AAA light… at that sale-price, not at its sticker-price.
Now… if Zanflare would make that critter an AA/14500 light, in the same style that the F3 looks like, I think they’d have a winner!
But please, for the love of B’harni (pbuh!), NO AR-coated glass to greenify the beam!
