Til this day i still edc this light……takes nimh or 14500 cells, but i like to use 14500’s to power this light. Who remembers this oldie but goodie Nitecore. Please add a pic of your most used light over the years.
EDC since 2012 has been my Trustfire F20:
This light has been posted repeatedly, as it sees more use as my ideal EDC than any of my other lights. Highly modded, with CW XM-L2 emitter, Nanjg 101AK no-blinky driver, aftermarket reflector, and replacement switch, etc.
This D10 still has the Q5 led lol….old emitter for and old light. Wish they brought this light back with a new emitter.
I EDC an old eagletac D25 Ti originally XM-L now upgraded to XPL-HI
Nitecore Tube 
The two lights I EDC’d on a regular basis are both, sadly, lost. They were an old itp a3 and a Fenix l0d. Now, I rotate through all the small lights I own.
Manker E02 at the moment.
For the recent 3 years, my most EDCed light was Xiaomi Mi4c.
Before that a custom Peak Eiger Ultra. Now Emisar D4.
I’m using a Lumintop Tool at the moment, thinking of switching it out with the Manker E02 nichia. I have a thing for EDC’ing AAA lights 
Me too, mine is equipped with Nichia 219B.
I also have an Emisar D4 (with Nichia 219C) with my car keys.
BLF A6
Most used over the past years certainly the D25Cti nichia, now days with a Biscotti driver. More recently I will grab the s 1 mini with 5D led for the smaller size and warmer tint.
Wow both nice lights……like the Eagle tac…….did you put trits in those slots.
Yes it has trits in both slots. Its still a realy nice the light, grab it if I want a small throwy nichia. The Olight is better for close range with its fat tir hotspot.
I am looking at the MT10A as my new EDC……also looking at another 18650 light for work.
These are my two favs for now…….for work, looking for a smaller form factor.
Mine change about quite a bit, for now in work a little ZL
Also use a g2 with a 219b mule
Most of my work lights i swap around with, stainless LT2 is in tool bag, others are either on me or in tool box
Olight m20vn has a 219b in, the Solarforcc L2T 219c 5700k/P1 219c 5000k/sc62d Luxion hi cri 5000k/6p sportac triple 219b/G2 219b 4500k/T10s xp-g2 CW and Convoy xp-e2 4000k on keys.
At home right now, any one of these(always have a cooyoo quantum on my car keys as well.)
All the above are 5000k or less, only the PK PR1 which is around 6000k to my eyes.
Generally my fav is 16340 for EDC ,
odd 18350 use at times as well. With the D4 and a couple of zebralights being so compact yet benefits of an 18650 fuel tank, these now form part of my rotation. Also depends what i am wearing, come winter and the large coats come out, larger 16650/18650 lights(like typical p60 hosts) get EDC use. These are concealed in inside coat pocket/s.
If we count EDC as “being with you at all times, including inside your home in lounge wear”, mine is a LT Tool CRI. It’s religiously on the collar of my shirt, be it old clothes to stay at home, the undershirt when going out, heck, even the PJs incase a nighttime loo trip is needed. Mostly, though, it’s a backup for something bigger.
I EDC an 18650 torch whenever my bottoms have pockets. From March up to this Friday, my go-to was a Convoy M1 7135*8 in 7A running Biscotti. Now I intend on swapping it for the S2 7135*6 in 4C, also running Biscotti, that just arrived. The M1 is decorating my wardrobe until I receive the lenses that are on the mail (the one on it is cracked thanks to a fumbled drop).
On my backpack is my trusty C8. Always.
Its funny how in the winter we seem to carry bigger lights………lol. In the summer i carry something small and compact and usually dont worry about what battery i throw in (nimh or lith)…….but in the winter its 18650 for the long runtimes. Clipped to my backpack i have an extra 18650 and 14500 and the light there is a T1 by Solarforce.
Funny you should say that… where I live, winter is at a close and days are getting longer. And yet, the need for burlier batteries increases as well. Over here in winter the days are short but totally clear of clouds and wind because of drought season, while spring, summer and autumn have as a signature long dark and rainy days, with dramatically increased chances of power outages (especially at my work, where the power grid is rickety even in good weather).
