Since everyone’s sharing, here’s my cherry-pick:
(to note, my collection is quite limited, so don’t expect too much)
AAA: Thrunite Ti3.
Why: Firefly first, great runtimes on the 2 lower modes, versatility, practically no size or weight, and mine is the rare example of an XP-G2 with an absolutely beautiful tint.
AA: Thrunite T10.
Why: Aimplicity and ease to use (only 3 modes that are easy to navigate thru), light weight, goes to firefly when first switched after turned on and ramps up from there, and pleasant beam pattern (very wide spill with large hotspot, almost like a TIR).
18650: Thrunite TN12 2014.
Why: Lovable mode distribution, just the right size to operate one-handed, serves as a self-defense tactical light in a desperate pinch.
Runner-ups:
AAA: Fenix E01.
Why: Legendary durability, exceptional runtime, can’t get any simpler than that.
Why not: No pocket clip. (Purple tint and ovoid beam don’t matter to me when I’m using an AAA, it’s my backup so I’m not gonna hunt white walls with it).
AA: Jetbeam BA20.
Why: Simple with only 2 modes, comfortable UI (head loose or tight for low or hi modes respectively), feels good in the hand.
Why not: Don’t have it anymore
18650: Convoy C8 with OP reflector.
Why: Wonderful invisible PWM, beautiful beam pattern that allows it to be used at close range with no problems, nice feeling with just the perfect balance between heft and compact-ness.
Why not: Annoying UI switching (I use it a lot on Low, and have to mentally measure the seconds so as to not change mode groups) due to old firmware (I have a feeling that one with TK’s new firmware would shoot to the top of my list easily), clunky to pocket (don’t have the clip for it or the dosh to buy it), relatively short runtimes and no sub-lumen level.
I also have a few lights that are pure NOPE, but this is not the thread to post them.
