Was a bit pricey 
On my keyring is a Trustfire Mini01 with CR123 in it.
In my pocket is a Sunwayman V11R with 16340 in it.
Im happy with both.
Theyve lasted a year or so now.
No marks on the V11R but I tend to make sure it’s in my pocket with nothing else. The Mini is on a keyring but I havent really looked for marks. I would assume it would have a few blemishes by now.
They both work great for the type of use they are designed for. They arent much good for hunting, but will stop you falling in hole at night, and can light up letter box numbers etc and so anything in between too.
V11R runs through its batteries, although rechargeable, but the Mini seems to last ages on one primary and is perfect backup.
So what is the flashlight you carry in your pocket and/or on your keychain? Pocket: NiteCore D10 and on the keychain: Eoslamp SP11-S2
•Is it a AA or AAA or lion? AA and AAA lithium primaries
•Why’d you choose that one? Had a lot of lights over the years, like how easy it is to upgrade the D10, also very durable.
•How long have you been carrying it? Since 2009 for the D10, and the SP11-S2 since 2014.
•How often do you use it? Daily.
•How’s it working for you? Better than I expected.
•How’s the wear-n-tear on the finish? Not so good and great, the NiteCore anodize is pretty easily abused. The stainless SP11 is no problem, of course.
The D10 is on it’s 3rd emitter upgrade. I just took a NiteCore EX-10 in trade for a Victorinox knife mod. After placing a neutral XML in it and fitting a Eagletac clip, it may become my new pocket light. 
Time will tell.
I have a Fenix E01 on my keychain. I usually have some other light in my pocket.
Is it a AA or AAA or lion? AAA
Why’d you choose that one? Good experience with Fenix and the batteries last forever.
How long have you been carrying it? 5 or 6 years
How often do you use it? About twice a month
How’s it working for you? Great
How’s the wear-n-tear on the finish? Wear on the edges but good everywhere else
Do you carry more than one? I usually have a pocket light: Nitecore EC21, Sunwayman M10R, Ti Quark, Microstream, HDS Rotary.

That was quick!
My EDC is a Fenix LD-01 in stainless.
Is it a AA or AAA or lion? AAA
Why’d you choose that one? I liked everything about it.
How long have you been carrying it? About 2 or 3 years.
How often do you use it? Maybe 3 or 4 times per week.
How’s it working for you? Like new, as expected.
How’s the wear-n-tear on the finish? The stainless developed some ‘patina’ from being in my pocket with car keys, coins, screws, etcetera, and being dropped and used. The patina hasn’t changed at all in years. Still a good-looking unit. Looks like new minus some gloss.
… and besides. Not many are aware of this, but the stainless version stores some emergency snob appeal under the tailcap. Comes in handy.

Happy camper
FandyFire S1-1
-AAA (Energizer Ultimate Lithium 1.5V)
-Cheap and tiny single mode twisty.
-About a year so far.
-Several times a week.

-It has some scratches due to contact with concrete.
-Yes…a smartphone with flashlight application…
This is my work EDC.Tiny XP-C flashlight with nice ratio of flood and throw.Fits in the side pocket of Leatherman holster.Too bright for close range work indoors,few modes would be nice.Glass lens, plastic reflector and nice anodizing.
Is it a AA or AAA or lion?
Preon 2 Ti in a shirt pocket & Maglite LED Solitaire in a pants pocket, constantly, both with lithium AAA primaries. Larger ‘coat pocket’ lights at night outdoors.
Why’d you choose that one?
Size, weight, adequate performance & reliability.
How long have you been carrying it?
2 years +
How often do you use it?
Preon 2 daily multiple times, Maglite rarely.
How’s it working for you?
Perfectly. I’m so fond of the Preon 2 that I bought a spare, ‘just in case’.
How’s the wear-n-tear on the finish?
Preon 2 shows no wear, Maglite shows heavy wear.
Do you carry more than one?
Yes, as above.
If you are referring to being able to use a 10440 "under the tail cap", then I get it. 
I appreciate all the replies to the thread. It has really been an education, and fun looking up all the lights mentioned. I see several peanut lighters in the keychain pics as well. Got a good deal on 4 of them for $11.99 off Ebay (I see they went up to $13.99). Now I see them even cheaper, around like $2.49 or so. I replaced the little O-ring with a thicker version. I’m keeping track of how long it goes before having to refuel the peanut lighter and my Zippo lighter with ranger band. I don’t smoke but like having a lighter in case I need fire.
Got a test thread going here.
So far I’m on day 23 without having to refill either.
Really liking the Fenix E05.
So what is the flashlight you carry in your pocket and/or on your keychain?
keychain: Jetbeam Mini-1
Pocket: Manker T01, Utorch UT01
- Is it a AA or AAA or lion? Mini-1: 10180 Li-Ion T01: IMR14500 UT01: 14500
- Why’d you choose that one? Mini-1: Tons of light in a very small, rechargeable package (130Lm on max). T01: Compact thrower, nice UI w/ good modes. UT01: Compact flooder, common UI with T01. Both can also run AA.
- How long have you been carrying it? Mini-1: 9 months. T01: 6 months UT01: 6 weeks.
- How often do you use it? Mini-1: Rarely. Only when occasion prohibits the others. T01: Occasionally. Few times a month. UT01: Every work day.
- How’s it working for you? Great, Happy with what I carry and how I carry it. Rarely need to go to my pack for a big light.
- How’s the wear-n-tear on the finish? Mini-1 is SS, very little wear. Others are in separate pockets, so they don’t get banged up. I don’t really care, just want to know exactly where they are.
- Do you carry more than one? Yes. Keychain, pocket thrower, pocket flooder
Soon the Mini-1 will be replaced by a Mini-1 Ti. Freeme’s got a killer deal that expires soon. I’m upgrading because the Mini-1 Ti has a 2 way clip that I can use with a ballcap for an impromptu headlamp.
Oh, have a Maratac TFP AAA on my placket of my shirt. Makes for a nice hands free light, personal flood. Not very tactical.
Nice poll. A lot of interesting answers. 
I was very torn between the Utorch UT01 and the On the Road M3. I went back and forth on which one to order. They’re on special right now so they’re only $3 apart in price. I finally decided on the OTR M3 since it is slightly smaller, has the low power warning and the magnatized tail. And the run times are listed as being a bit longer. We’ll see how it does when it arrives.
I still have the Fenix E05 but have put it on the keychain with my vehicle keys. I have the Thrunite TiS on my ‘survival’ keychain along with the peanut lighter and SAK.
I have the OTR M3 also. Also OLight S1, S10RII, and a few other 16340/CR123A lights. The reason I opted for the Manker and UTorch was for AA compatibility. The UT01 is surprising small. It’s very close to the Jet-1. Slimmer than the 16340 lights, too.
Honestly, there are so many good lights out there and I’m barely scratching the surface. LOL And they keep making newer, brighter and better ones. Worse than a drug addiction. Or is it better?
- Is it a AA or AAA or lion? Li-ion? Varies between single cell: 16340, 14500, 18350, 18500 or 18650
- Why’d you choose that one? my pocket EDC varies depending on mood, what I just got or what I just modded.
- How long have you been carrying it? varies. But I change pocket lights often depending on mood. I might carry a light for 3 days, then put it aside for a different light, then go back to the first light for a week.
- How often do you use it? I probably use my EDC light at least a couple times each day. Usually for very brief periods.
- How’s it working for you? Works great
- How’s the wear-n-tear on the finish? Depends on the light. Lights with HAIII anodizing, bare aluminum, or bare titanium tend to look great. Lights with cheaper anodizing tend to look like crap (I carry my light in the same pocket as my keys).
- Do you carry more than one? Nope just one.
Alright, 2 years later and it’s time for an update, methinks 
- Current EDC is a TN12 (now in CW) at the same spot, a T10 in the right pocket near the cell phone (chest pocket when I’m wearing a shirt with one), and a Ti3 (NW this time, got another one) on the undershirt as before.
- Is it a AA or AAA or li-ion? The TN12 is li-ion, The Ti3 is AAA, the T10 is AA.
- Why’d you choose that one? The TN12 because it’s the powerhouse that’s there when called, the T10 because it’s the perfect compromise between compact-ness and runtime, and the Ti3 because I like a backup to my backup.
- How long have you been carrying it? The TN12 for about a year and a half, the Ti3 for two, and the T10 is bordering on four months.
- How often do you use it? All the time. The TN12 gets lit for a few minutes every night as I get close to home (many empty lots full of weeds, drug problems not far like in any big city, and a history of BnE’s in the district that could scale up to straight up robbery – not taking my chances, I’m lamping the heck out of any place that could hide a perp - though I could use an L6 for that), the T10 when it’s practical to have floody light at one click, and the Ti3 whenever I wanna do something while appreciating its beautiful tint :heart_eyes:
- How’s it working for you? Wonderfully! :+1: I have light at anytime I want for pretty much any circumstances imaginable for EDC, and three choices of pleasantly-tinted light at that :sunglasses:
- How’s the wear-n-tear on the finish? Not terrible. The tails of the TN12 and T10 are discolored on the very edges of the scallops from a few unfortunate drops, the T10’s clip is bleached where it hugs the body of the light, and the Ti3 has lost the anodizing on the outer rim of both bezel and tail (and a bit on the clip too) plus the bezel has a minimally flattened spot where it fell from over two meters (wow, this thing is tough). Overall, you can look at my torches and say they’re definitely used, just not every single day.
- Do you carry more than one? 1, 2, 3… look ma, I can count! Just kidding. But I do have more than these on my kit as a whole: I have an Olight S2 Baton that currently rides on the shoulder strap of my backpack, an S1 Baton that’s pretty much permanently attached to my ball cap as a headlamp, and a Convoy C8 (7135x8 with an XM-L2 T6 4C on OP reflector) that goes on a pocket in said backpack as a “car light” that I don’t leave in my car. I swear I’m more jealous of that torch than my car as a whole
ADDENDUM: If anyone’s wondering about the E01 from last update, I have a cousin that’s very likely making great use of it. Smart girl and a budding flashaholic, so gotta put in the incentive there 
It has been a couple years since I saw this thread. My favorites have changed a bit.
- Keychain light: Cooyoo Quantum SS
- Necklace: DQG Fairy
- EDC: Olight S Mini
Those are the smallest ones I use often, but there are a whole lot of others which get frequent use. They’re just … bigger, and mostly modded.
For extended use, 1x18650 lights are generally where it’s at.
What I like about this thread is, it confirms that I’m not alone. I might still be crazy, but I’m not the only one.
