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

I have a decent deal for it. https://budgetlightforum.com/t/-/58182

Yeah, percentages are on amps - I got:

Low: 10mA (6mA)
Med: 170mA (180mA)
High: 1.8A (1.8A)
Turbo: 6A (6A)

Amounts in brackets are what the percentages in the description work out to be. So low is higher, medium is slightly lower, but high and turbo are dead on.

Finally S12 sst20 2700k has arrived! Yeah!!

Still daylight though, but try it just for moment in dark room….wew! I CAN’T believe it…I am well amazed by High cri output, shined it on my messy clothes…perfect to me. S12 is my first high cri, triple led flashlight. I think in term on lumen, it is bright and flood. I still can’t figure, but I did comparison with 6500k xt21x. I will do it later.

2nd thing, don’t we should know about how much candela it is? since sst20 known for throwy. I see this thing could do a lil bit of throw. Let see after night.

else, it was smaller and short than I was thought. Imagine 21700 cell, longer and bigger…s12 is really compact which is great! Smaller but brighter indeed. :laughing: anywany Vapcell 21700 4500mah red one I use fit well, just well enough…

I went Nichia because I’ve found the SST20s Simon sources are just too green for me. That said, next step is to put SST10 365nm in this thing.

XPL-HI’s in A and D tint bins have superior tint over it.

Another better option would be scalped 90CRI LH351D’s which are described as having a beam profile of something between HD and HI and have an extremely consistent near zero duv.

Just done testing.

Brighter, yes. I’m absolutely agree. In term of flood, it got usable spill. Although it used smooth reflector, the flood is wider and and I think the reason it got bit of throw.

Tint ? I choose 2700k bcos our eyes will feel better and yes, it felt much better than 6500k. But, I have to agree with mocarny, in green forest I thought it will light the green. Well it look not. But fine for me. 2700k become one my fav tint now.

I’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. It’s the shortest 21700 light I have…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 I’ll use XPL HD another LED in the future… Or maybe this LH351D’s.

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

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

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

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

You guy go try to mode em’ first, tell me if it work well later… :wink:

Funny, i added an R050 as well :wink:

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?

That’s the sensing resistor - if you run something in parallel with it, it’ll adjust the maximum amps. I’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 they’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.

Nice review. I don’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.

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:

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… :person_facepalming:

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 :+1:
