Thanks Simon. I think I’ll wait for the new upgraded version of M3.
btw, what is the name of this new M3? Is it M3A? or M3C-U ?

Beside that, I’m still waiting for my SST40 S2+ , I’ll be checking it first and see how much I’ll like the 5000K SST40.
I wonder if the L21A CULPM1 beam is going to be too narrow with its 64 mm diameter head. Maybe a SBT 90.2 will fit better in that flashlight giving a wider beam? Looks like the 44 mm head of M21 is a limit, or the M3 48 mm. I don’t need more than 1km throw anyway.
It is not a single CCT but a range. Someone already posted the chromacity bin that Simon sell is ebxD46. You can go to the datasheet and find the CCT and DUV range of this bin by plugging the coordinates into this website. Osram does not specify a specific CCT.
Here are the datasheets
What is the difference between culpm1 and cslpm1?
Footprint c(u,s)lpm1
S 3030 footprint (max 6A?)
U 4040 footprint (more current 8A)
Led Size csl(p,n)m1
N 1 mm2
P 2 mm2
Colour Last two numbers cslpm1.(tg, fy, 23, f1, 13, 14)
TG 6000K
FY Yellow
23 Red
F1 Pure Green
13 True Green
14 Blue
Thanks RapidLux.
Will be any difference in lumens between culpm1 and cslpm1 at 3A current?
Not appreciably. The main advantage (still theoretical right now as it hasn’t been tested AFIK) is a higher peak current before its thermally bottlenecked. In other words, other than binning differences, CULPM1 will be about the same as CSLPM1 until current exceeds ~5-6A. And in a flashlight with other thermal limitations, maybe less of a difference will be seen. TBD with time
Whoops, just not used to typing out the model number of the 4040 version now that they’re available! 
Hello Simon,
Can you get Osram KY CSLNM1.FY (yellow) emitters?
I would be very interested in a thrower flashlight fitted with that particular emitter, if you can source them.
Probably I would take a Convoy M21A, but if you can fit it into a Convoy L21A, that would be even better.

It is a buck constant current drive,
Maybe M3-C, C means “type-c”.
I will try to order,
It would be nice to see M31C, 21700 size
Hi cri throwers
What centering ring did you use?
i’m ready to launch a M21C-U with type-c port
Stock, supplied with flashlight
