Doing some reading about this the last couple evenings…certainly gets a lot of praise and the process(es) are interesting. Definitely will pick one or a few of these up when he releases them in other models, looking forward to it!
i will update the link
Simon,
What is the output for the 519A?Max flux (@3000mA):
219B 500LM ~
219C / SST20 4000K 3000K 650LM ~
LH351D 800LM ~
SST20 6500K / 5000K 1000LM
887LM ,test from djozz
Whoa, I just noticed on the Convoy Ali store that there is a new model! Convoy S3
Never even announced it?
I really like the knurling on it.Is there anything else differentiating it from the S2+?
i had S4 S5 S7 before, they have the same deep reflector as S2

Is it possible to buy the TIR lenses and the driver separately?

The S3 has been around for years. Lot’s of reviews here on the differences.
Hm, oh… lol
I hadnt seen it before. Its at the top of the homepage under “new arrive” with only 11 sales and no reviews.Yeah, oldie and still a goodie. It’s just a smidge shorter than the S2+ (like 3-4mm iirc) and the reflector is shallower. Steel bezel ring screws into the head…nice touch like on many other lights. I like that squared checkering compared to the usual 30° diamond knurl. Maybe not as grippy, but gives enough grip and feels really nice.
Here’s the search results for S3 in his store…if that shows up for you (.com vs .ca in aliworld): Convoy flashlight Store - Amazing products with exclusive discounts on AliExpress
I keep seeing praise for the S21B over the S21A because of the integrated shelf, but there’s not much mention of the S3 over the S2+ for the same reason. The S3 also has very few orders compared to the S2. Seems like not many people even know that the S3 exists. Is it time to recommend the S3 over the S2?

Can we get beamshots of the different optics?

For me, the reason I didn’t order a S3 over the S2+ was due to the lack of 18350 tube, and other colors, but I actually prefer the knurling on the S3 and the SS bezel is much easier to get to the emitter as well.
I also like S3 more. To my eye it seems to have even little bit better quality than S2+. Sad there’s only two colors available.

I wonder why it hasn’t replaced the S2+, isn’t a shelf design much better than a pill ? Better thermal conduction to the body, lighter, no brass pill to manufacture (lower cost ?), and with only one retaining ring (no pill retaining ring) there would be no need for reduced driver diameter, so it could be 21mm instead of 17mm, which would simplify greatly the development of a boost driver. Unfortunately it’s still reduced on the S3 (17mm).

The S2+/S21A is nicer to mod due to the pill design which can be screwed in a bit more or less when you modify the reflector

It also makes trying different leds and optics easier. S21B has 22mm driver, when S21A has 20mm. At least in that model you can see the benefits of that construction.

I hadn’t thought of that, but is it the only advantage ? Adjustment could still be done with thicker lens, thicker MCPCB or spacer.
Yeah, pill makes fine tuning easier, I have to admit.

yeah but making mm-correct spacers is a chore
also personally I dislike soldering through the reflector opening as opposed to on a pill in the open

i can send some TIR lenses to your for free, just note this in the remarks.
About the 12A FET driver, The manufacturer didn’t want me to sell this driver. You can consider the new version of 8A 12 groups driver.

OK, I’ll take some time to take some pictures.
@Simon, any idea when the SFT40 5000-5700K and the new 17mm 6V boost driver will be available?
LUMINUS may not produce 5000-5700k sft40,
I got 17mm 6V 4A driver sample , But I’m not sure which LED to apply it to, what about XHP50.3 HI ?
