Why not? They are only just a small little bit more in volume.
Perhaps I’ve not seen a “slim” version of an 18350? All the ones I have seen are quite bulky.
I like to take it to work, and for work I have to wear smart trousers. A bulky light is quite uncomfortable.
That’s why I recommended to you to buy some 18350s.
Plop them in if you really need some power/runtime.
Otherwise, just stick to 16340s most of the time when you don’t need super high power.
Any specific 18350 people recommend?
This one:
And that’s the only one?
Of course not:
Cheaper KeepPower one is out of stock though:
Excellent, thank you.
So either Vapcell and KeepPower are the brands to go for.
HDS are also quite large, and heavy
Olight S Mini are quite small, and much brighter than an HDS,
also much less expensive, but do not have the LED you want…
Maybe CRX could mod one for you… he can also do your HDS LED swap, he is in Edinburgh
the N219b CRI Ra is more than 90
PLUS it has some of the highest CRI R9 (the Red part), of any LED available.
HDS used some, set to 200 lumens.
Here is a Titanium Olight S Mini next to an HDS Rotary, for size reference
personally I choose not to use 18350 (they are unprotected), I much prefer Protected 16340, particularly the ones that can be recharged by USB, like the Olight version in the photo.
The Titanium S Mini has a NW emitter btw… I hate the tint and the Low CRI, but tastes vary, ToyKeeper likes it.
I sent you a PM also.
Same here. I find the D4 to big for this and almost always EDC one of my 16340 lights.
Can someone link me up to CRX contact details please?

As I used Liteflux LF3XT in the past, my new BLF A6 is the actual favorite EDC:
From 23 to 24mm diameter and from 80 to 87mm length.
BLF A6 = easy to use with good modes for me, cheap, much more powerful than the Liteflux and likewise reliable.
Liteflux was some of the best of it’s age, but that’s more then ten years ago…
Yup, those are the best high drain cells for the Emisar 
First they were sold as “Aspire” but now they have those brands!
BTW, and just because I’ve been following the conversation here, I know what you feel about carrying the 16340s/CR123A. Recently I’ve been buying and using my flashlights that use those cells (On The Road M1 / i3 / M3 Pro, Jetbeam RRT01, Olight S1R Baton / M1T Raider) and I know that they are thinner than the 18350s. But they don’t have the same “kick” in power/output and have smaller runtimes.
However, if you want to have longer runtimes and have your pocket with a “thin” flashlight, you can try using 14500 flashlights!
Some 14500 Li-Ion batteries will give more runtime that 16340s and eventually more “kick” on the output. As example, recently a Vapcell 14500 1000mAh was released. So it will have more juice to run than a 700mAh 16340 battery!
It is just a note/suggestion
About CRX, here is his user profile: http://budgetlightforum.com/user/7164
And here is his mods & builds thread: CRX Flashlight Builds
Hope he can help you modding any light you may have under sight
I don’t have a photo on hand, but an 18650 D4 fits perfectly inside a Leatherman Wave holster. Since these are available in smart leather, they are perfect for formal wear on a leather belt.
I think your picture is the perfect conclusion on what is an EDC light. Even if I own about 40 lights, my Smini is my no.1 EDC light. I would take it before any of my HDS for EDC.
I like everything about Olight S Minis, except they are Low CRI, and not N219b compatible (they use XM-L2 architecture). There IS One High CRI version, the Olight S1 Mini High CRI. But the LED is XP-G3, with very green tint, and modding that model is difficult (the bezel is sunk into the body and removal is destructive).
for small 16340 with High CRI off the shelf, the Klarus Mi1c is a winner.
FWIW, that particular light does Not use an Aspheric lens, it has a reflector, a wide spill, and a throwy hotspot.
The Klarus UI is not my favorite, requires a long press to turn off.
But the light is small, very pocketable, and it includes a USB rechargeable battery. No charger required, just a phone cord.
There are also copper and titanium versions,
they are Low CRI, but not difficult to modify to N219b, CRX could do it easily.
Just drop him a PM mate!
