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

Yep, enjoyed. Thanks. I have 2700K version and enjoying it more than I was expecting.

Sorry, I don’t have :frowning:

Maybe I got allergic to warm colors recently… I compared my S12 4000K with Convoy H1 4200K and S12 looks more neutral, H1 is rosy :weary:

I think I’ll get SST20 5000K and finally judge which one is better for me. On white wall S12 indeed looks very neutral, but in forest strange things start to happen and I see it more yellowish and it bothers me.

Nice review :+1:

:person_facepalming:

You’d better get 3A XPL-HI’s instead.

Great video very helpful insight.

So, 7xSST20 5000K flashlight is on the way to me, :smiley: so I’ll try and check if it’s as bad as you’re saying. HI is too much throwy, but maybe I’ll get HD, 3C or 3D. Will see.

I was using Wizard Pro NW, which is cold white, during my beamshots, I think it’s the reason S12 Nichia looked so yellow to me. In fact, SST20 4000K in FW3A is less yellowish than Nichia in S12, I compared both today.

Edit: I added first 15 min of 100, cooled with a fan, and not cooled for comparison. I was sure this host can sustain 100, 1600lm for pretty long

The C8F is much cooler with a well-defined hotspot, compared to the S12 w/ 219c. :slight_smile:

I haven’t done any measurements or an extensive comparison, but both lights are different enough that I see myself using both regularly.

SST-20s are throwier than X-PL HIs…

Yes, I know, this light is for review, and they wanted to send SST20 instead of XPL, so… But throwy SST20 with TIR optics like in FW3A looks great to me, and in S12 is smooth reflector, so I’d like to have more floody LED

Ah, you’re comparing with the 219C, not SST-20. Thought you meant X-PL HI vs SST-20 in that other light you just bought.

LH351D would probably be a good match for the S12, very similar beam profile to X-PL HD.

Convoy S12 used a 6amp CB or driver and triple led. So it draw about 6amp or 5800mA at full throttle which able to run it for 2 minutes.

What were your thought about heat dissipation/loss vs power output which in term of lumen…do you think this is the best outputing level for a 21700 battery? Have you ever think if there was a flaw and probably there a room of improvement, what would it be?

I order the S12 in 2700k version, it should be pick by today. Can’t wait actually. :laughing:

And i have got 219C 5700K...BLOODY WONDERFULL!!!

I thought it will be too cool but guess not. It looks like 219C 5000K 90CRI (but to my old eyes more yellowish), last Hank had in the store before withdrawing them.

Now i'm sure that using big size flashlights are meant for 5000K (not colder) and smaller like FW goes better with 4000K.

S12 can sustain Turbo much longer than 2 min, the test was in cardboard box with no cooling and even worse than standing on a table. Second test was fan cooled, 4 min turbo. When I was taking beamshots to this review, there were pretty cold in the forest, and S12 got seriously hot after about 4 min.

Output is very good for me, of course there are 21700 lights with more and more lumens, but you know, battery will be drained very quick. 1600lm is ok for what I use flashlight for (wandering in the forest, listening calm music and thinking about life…yeah). And some campings and mountains, but I prefer headlamp then. In fact, I use it on 3% most of the time, and 30% sometimes. I use 100% rarely (it drains battery pretty fast), so I don’t care that much about Turbo runtime - 2 or 2,5 min, whatever.

Not much to improve for me now, I really like my Nichia version as it is, it is in fact more yellowish than SST 4000K in FW3A, but still not that bad. If I bought SST version, I’d probably use Dc-Fix to have more even beam.

To add to Mocarny’s data, these are my runtime charts - at about the three minute mark, I was at 90% relative brightness then it starting heading down fast. This was indoors at around 23 degrees C, no cooling. Bottom chart is just a zoom of the first 10 minutes.

Thank you :slight_smile:
It looks like mine - don’t you have a feeling the 30% mode is more like 38% ? It stepped down to about 38, and when I checked lumens, it looks like maybe ~ 35.

The percentages are amperage, not output. Due to the non-linear current response of LEDs those numbers not matching is normal.

Where is the best place to get this light?

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.

/shrug

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…
