Thank you, I’ll order these right away 
This will be great with KW CULPM1.TG. We need only 4040 gaskets.
Do you plan OP reflector for S21B?
4040 copper MCPCB is in stock now ,
4040 gasket will be availabe at next week
you can note “OP reflector” in the remarks of your order
I am looking for a work light with decent color rendering, do you plan to sell any high CRI, COB LED based, portable lantern someday ?

CREE has many types of COB LEDs, I think it is not difficult to design this, it does not even need a reflector.
Oh,thank you ,i’m adding more items.
C8 KW CSLNM1.TG
C8+ KW CSLNM1.TG
S21A black
4040 20mm 16mm copper MCPCB.
Next week ,i will add links of other osram LED flashlights.
i got driver for KR CSLNM1.23 and 8A driver for KW CULPM1.TG
My wallet....
Annoying but i can't help my self, S21B in grey color, will it be available also? I have only grey Convoys, wouldn't change now to black S21B.
Eagerly waiting for the 4040 gaskets and the 22mm 8A driver to put it together with a CULPM1.TG in a L21a
Same here, that’s what I’m waiting for. I’m also getting a few of the Osram red driver.
Currently using the 8*7135 on the red and it starts out at 230 lumens, drops to 60% within 15 minutes and runs for a further 60min. Since the forward voltage is 2.5v it should run much better with this new driver.
first batch only black ,sorry
i have samples ,i will assemble one L21A with 8A driver and CULPM1.TG at next week ,and test the data
Finally black S21A! I’ve waited a long time for this. Can you measure the inner diameter of the battery tube? I am also interested in the thickness of the walls.
But what about the XHP50.2 emitter version? 
Simon doesn't like yellow corona crap which is not present with SST40 and i totally agree with him.
Thanks Simon, it’s in my wishlist now.
BTW I’m the 2nd person who has put this item in wishlist, I’m wondering who’s first … :sunglasses:
The same as in S21A, S12...
Exactly it is UGLY.
Slicing improves it though
That would be me LOOOOL
But i am waiting for grey version. My OCD doesn't allow me to buy black Convoy
