[Review] Convoy S12 - the best Convoy's flashlight?

LED Flashlights ā€“ General Info 21700 Flashlights
27

Iā€™m happy you like it, so my WOW about S12 is confirmed.

S12 is short indeed, longer than S2+ and shorter than M3, just in the middle between them. Itā€™s the shortest 21700 light I haveā€¦I mean except Imalent DM70 that is disgustingly short as 21700, shorter than S2+ .

I went Nichia too, because of more flood and no tint shift I heard of. Not as much CRI as SST, but very good, a little bit too yellowish, but maybe Iā€™ll use XPL HD another LED in the futureā€¦ Or maybe this LH351Dā€™s.

What do you use that powerfull UV light for, oweban?

28

Just for fun - Iā€™ve got plenty of lights that can compensate, but would love a UV light with more punch than the S2+ that Iā€™ve got :slight_smile:

29

Temperature stepdown can be easily removed on these convoy 6A drivers.
Also by stacking sense resistors output can be set higher or lower.

30

Yep! Added an R050 to my S11; 7.2A is close to perfect for SST40 :wink:

31

You guy go try to mode emā€™ first, tell me if it work well laterā€¦ :wink:

32

Funny, i added an R050 as well :wink:

33

Temperature sensor bothers me in M3, but in S12 flashlight gets really hot before step down, so I assume inside is really hot, I definitely want to keep it.

But this sense resistor in SST40, tell me more :nerd_face: Where to solder it?

34

Thatā€™s the sensing resistor - if you run something in parallel with it, itā€™ll adjust the maximum amps. Iā€™ll list the final current if you add one of the below resistors in parallel:

  • R010 - 12A
  • R015 - 10A
  • R020 - 9A
  • R025 - 8.4A
  • R050 - 7.2A

Note that theyā€™re 2010 (5025) resistors - I found it hard to find a mix bag of low resistance in 2010/5025; I got them in 2512 (6332), so the new one overhangs a bit.

35

Nice review. I donā€™t usually see people who describe as being allergic to warm light. I like things golden. Green is a funny color. Green seems to pop with cooler light, whereas some of the background colors come out more with warmer light. For instance, birch trees in summer look great under cool white at night. Mixed forest scenery looks more alive with warmer light.

36

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 :stuck_out_tongue:

I see, so stacking, not replacing this existing, thank you :wink:

37

So Iā€™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 youā€™ll see the differentā€¦

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 outā€¦ :person_facepalming:

Just my opinion though, any guess how this happen?

38

Iā€™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 theyā€™re not necessary.

39

The thermal regulation and performance of this light looks great. Thanks for the review.

40

With bezel the beam looks like a fat triangle, and without like a flower.

Soā€¦if you like fat triangles, use the bezel, but if you like flowers - remove that bezel :+1:

41

nice pics, thanx

42

So the stock resistor is a .1 ohm if I am reading the tables correctly? This would be 10*.01=ohms?

43

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.

44

Red version build

45

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.

46

Nice build :+1:
SO much red light, I used to like red light because of night vision, but itā€™s too uncomfortable for me now.
