I have. It’s in Convoy S3 with 5A driver. I like the beam quality of it. Little pinkish and about as throwy as Nichia 219C. It can’t take that 8000mA that they advertize. Phosphor turns to charcoal.
Are there any current coupon codes for KD?
The forever working BLF one.
:-)
inhave one sitting in my workshop. And the p70 also. Still need to try them. Waiting on a driver from Convoy.
I have placed about 6 orders in the last 2-3 months with Kaidoman. All for bare leds (which I never do bc of the high likelihood of them be8ng lost in shipment bc the pkg is so small) and all have come in OK. Still waiting on one in shipment. Never get shipment updates or anything though. I don't track them either .. free shipping is nice! Orders take about 12-16 days to get to eastern USA.
I did. They burn at 7A. The one I had started smoking at 7A but looked good. I switched off immediately and paired with 5A driver. Smoke again. After a while I saw a brown dot at the phosphor edge. I’m disappointed and feel like I don’t want it anymore…
BLF works for a 3% discount all the time.
They do occasionally have codes for 10% off, which is great but they come and go. The last one was "hall" during the Halloween weekend but it went away soon after the weekend was over.
New code came up yesterday - nov gets 10% off (says until end of November).
So made a small order for one "Triple Osram KW CSLPM1.TG LED with 20mm DTP Copper MCPCB Parallel with Optics " to put into a Convoy S2+ for a great little pocket thrower.... like i need want more 
pocket throwers.... but don't have one with three CSLPM1.TG LEDs. So why not build another pocket thrower.
So what’s the code?
type in the three letters -- nov
Oh! I had missed that.
BTW, what driver did you find? I presume 17mm. A triplet should draw much current (20+ amps).
I have a MantaRay S21 (an S2 w/21700) fitted with a CSLPM1 and a K0B with a CULPM1, both in tan colour. Considering the S2 in tan also, to complete the lineup. Maybe put the single Osram in there and use the larger S21 for the triplet as more choice in 20mm drivers – included TIR wouldn’t work though.
For the convoy s2 triples i have been using the BLF A6 A17DD FET+1 driver from here:
https://www.aliexpress.com/item/32814645491.html
It's inexpensive, works well, and i normally measure around 9 amps at the tail cap.... which is great for spreading across 3 LEDs. It does tend to get warm (i measured ~ 125-130 degrees F) before the automatic step-down from turbo kicks in after 45 seconds. Not bad. And bright as heck. And you can kick it right back into turbo if you want. I tend to wear gloves for doing this as it continues to build temperature, especially in the small lights like the S2+ and the S21s.
Some of my other builds easily reach 150-160 degrees F before the temperature limit kicks in using convoy's 5 or 6 amp drivers.
Almost all of my builds are convoy based BTW.
Side-note - i had tried a MTN FET driver some months ago but they were bad and i had to return them. Lisa and Richard were great to work with and a refund was no problem.
Kaidomain has been good to me over the years, except for when I ask a question or have a problem. It takes a long, long time for them to respond.
I’ve only had 1 problem so far, which I’m currently trying to work out with them.
I bought the quad LUMINUS SST-20 J3 JA3 WARM WHITE 2700K CRI95 LED EMITTER. After I put the flashlight together, I noticed 1 of the LEDs is dimmer than the others. So I initiated a return request thru their website and asked for a replacement. Also thru their website I submitted a Contact Us “enquiry”. And finally I replied to the order shipped email I got and included the pictures below. A week later, still nothing.
For the problem of "1 of the LEDs is dimmer than the others" it's probably due to a bad flow of the led to the mcpcb. I'd try and reflow just that led and see it that fixes it. If not then just replace the led yourself.
That seems…
I mean, I’ve got XHP emitters with varying brightness across the cores. This is just expected tbh.
HI
Sorry for the late reply.
Please try to see the LED is dimmer when you are putting the Quad LEDs on it?
Thank you
No stock of Luminus SFT40? Can’t find It anywhere 
Not late at all! The bottom left picture is when the quad optic is on the MCPCB and installed in the flashlight.
I did get a response from Kaidomain Sales this morning - yay! Maybe that was you BanL?
They offered to send me a replacement LED. Since I’m capable of reflowing, that sounded good to me. Hopefully the new LED will better match the other 3.
Probably not many people cares, but here's this LH351A emitter. And after some tinkering, I could find a downloadable LH351A datasheet here @ Datasheet4U.
Should look nice.
