Off the rack, I like the Jet-1 just for its utility, size, impossible-to-accidentally-turn-on twisty, and modes, even though I EDC-holster a custom ’502.
Custom made, yeah, I really like that ’502. 5000K XP-L, 1.4A driver, nice balance of brightness and runtime, nice white color, pretty smooth beam with lots of throw for when I go all Hirojen on invading mosquitoes. (My S2+ is a bit too floody for that, despite being brighter on high.) Lights up stuff across the yard quite nicely, too.
Honorable mention to my thrown-together C8 clone, 4300K XP-E2, 1A driver, not all that impressive close-up, but lights up trees nicely at a distance. Tightest beam I’ve seen in a while, only outdone by my L2.
I admit, it’s probably personal preference why I like the aforementioned ’502 and C8, because I built them the way I want them, not the way they’d come out of the box. Despite having other newer lights, those 2 are the ones I keep repeatedly coming back to. They’re my comfy warm blankets of the flashlight world.
Should play more with the Jet-2 (16340 version), maybe I’ll prefer that over the 1, dunno.
Xtar Moon Rc2, a very different light distribution, more useful for close quarter work, clips onto clothing for odd jobs and make a decent lamp in a crunch.
I wish it had a 1000 lumen mode
Not sure if the blf A6 qualifies as it debuted in 2015? Still love mine. Bought an astrolux S1 for a friend he takes it wherever he goes.
My choices are the copper Astrolux S3/Kronos X5 and the eagle eye X2r. I’ve bought 3 x2r for presents. With a protected battery, they’re virtually idiot proof. Like the neutral white tint too.
