Maybe the problem was this Wizard Pro NW 5700K, so after switching to S12 it was looking more yellowish than it should. Now I think, maybe I should have small AAA size 2700K light, to shine a bit before S12, so the S12 would look very neutral 
I see, so stacking, not replacing this existing, thank you 
So I’m guess everyone that own s12 has probaly seen how the beam profile look like. Well, it not look round due to reflector designed for 3 leds. It look like a shield shape.
But not just that, if you remove the stainless benzel away, you will yet see a different beam profile or should I say beam edge? you will noted a really nice flower-paddle shape beam. You guy try it on a white wall and I bet you’ll see the different…
It seem to me that, without the benzel look very nice beam edge than with benzel. But, the thing is, benzel is use for cover the lens from stick out… 
Just my opinion though, any guess how this happen?
I’ll take a look tonight - I like the petal shape beam, but the four notches in the bezel makes an extra line in it, and they’re not necessary.
The thermal regulation and performance of this light looks great. Thanks for the review.
With bezel the beam looks like a fat triangle, and without like a flower.
So…if you like fat triangles, use the bezel, but if you like flowers - remove that bezel 
nice pics, thanx
So the stock resistor is a .1 ohm if I am reading the tables correctly? This would be 10*.01=ohms?
R010 is 0.01 ohm - what I did was use this:
In the top set, 6 I and 0.01 R, gives 0.06v sensing - threw that in the second one along with common resistors (eg. R025 etc, 0.025 I) and it gave off the amps that would be added to 6A by putting that in parallel.
The best version?? I could say it YES
I own XT21X which used 21700 and now barely used them, since S12 came by, I like much of the tint, yet compact lighter and brighter. I loved it.
Nice build :+1:
SO much red light, I used to like red light because of night vision, but it’s too uncomfortable for me now.
Thanks. I agree, white light is way more comfortable. RED looks like 0 CRI with black pools. Sometimes scary 
but has advantages too.
Why do you write “now”? Has there happened anything making red light less comfortable for you than it used to be before?
Hmm let me think… Previously I was fascinated about red light - it’s very good for night vision, so good for sky watching. But now I’m not as fascinated in sky and stars and flares as before, so I’m not using it. It would be still nice to have a red light in my headlamp, but 30lm red light is for just illuminating things near me, not for walking - I can’t find practical use for red light now.
Isn’t it uncomfortable for eyes to walk with your red light for e.g 20 min?
It is. After a while I feel like on a different planet but maybe it just requires getting used to it. And it looks much better in accompany of other light, moon light or dusk/sunrise. In complete darkness it feels like getting inside Diablo 3 :smiling_imp:
It is said that red light helps to fall asleep…so be careful when walking with that much of red light, because you can suddenly fall on the ground and fall asleep.
Got myself a S12 SST-20 4000K.
Almost perfect. Almost the best convoy light.
Wonderfull shape, design, haptics, optics, beam, tint, 21700, mode spacing, temperature control.
but:
UI just middle age. Massive downgrade from biscotti UI.
Wanted to see it with my own eyes,
but the light will end up unused because i very much dislike unpredictable start mode.
I personally like this UI - it is simple, 4 modes and that’s it. We have Andurils and other complicated UIs, but here is simple UI for non flashaholics too. And Convoy seems (for me) to start making flashlights like for some kind of apocalypse - very thick walls and glass, simple UI. M3 is a great example - so heavy and sturdy.
And mode memory? It is like bicycle gears - you have to think ahead to lower the gear before stopping, if you don’t, it’s very hard to move. And somehow no one is complaining and saying “make auto first gear function when stopping”
Hi Mocarny,
first of all: thank you very much for this review. i realy enjoyed it.
second: i have not bought the light because of this particular review, zero complain or offense
i just put my “i don’t like the UI” post here because the title of your post “inspired” me to do so
Agree on the Convoy is a great brand and builds great lights.
Agree on the Anduril versus “easy to use UI”. For most of my lights i prefer an easy UI
But this (S12 and other recent Convoys) UI isn’t easy for me.
4 modes: great
Simple UI: great
I also like the stock Mode Spacing
But i like to configure (once) Mode Memory +Off+/On and Mode Sequence +Down+/Up to my taste.
Biscotti also allows choosing from different Mode Groups. Not a must for me, but i prefer even 3 Modes over 4 Modes
What i don’t like is starting somewhere in the Mode Sequence were i ended up last time (and i don’t remember) or accidentally ended up (some seconds/minutes before)
It makes me advance all modes until i am sure i am in Turbo or High (and this is what i very much dislike)
1. Turbo because i want Max Output: Now
2. High because i like to use it longer but at max sustainable Output
Thank you 
I agree. It would be nice to have ability to turn mode memory on and off. I like mode memory, so it’s ok for me, but I understand there are lots of people that don’t like it.
Maybe something will change in the future… My personal best would be: one group 4 modes with memory on, and after e.g 5 clicks, other modes group, 3 modes with memory off.
How does the LVP work? Does it shut down or just give you a single “blip”? If it’s a single “blip” does it repeat? I’m always afraid I’ll miss those blips.
