I've EDC'd something like this for about sixteen years. This is the RovyVon Aurora A5 (G3)-UV + White with the Nichia 219C LED. I mostly just use the UV to give the glow in the dark case a little charge as I'm dropping it on the nightstand.
It's not my first A5 - I've killed one in the washing machine. I replaced that one with a Fenix E05R which is way more washing machine proof, but I just never had the same love for it as I do for the A5.
Before those, for many years it was the Fenix LD01 - mine has that wonderful beat up look you only get from using a light every day for years.
There's also been a number of no-name 10440 lights that I seem to lose more easily than the brand name ones :-/
In the same pocket is an Olight i1R 2 on my keys - so it also has the 'well worn' look.
Manker E02II NW (with a 4000K SST-20 that actually has a nice tint)
+ a D2 (519A 3500K domed + W1 6000K) in my handbag.
I really like small right angle lights!
The Emisar? I'm learning so much from this thread! This looks like a great concept.
