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
I LOL when reading this :
Me too, I wanna buy this S21B. imo S21B is the new S2+ , this new style is so excitin. S21B is so cool :nerd_face:
S21B and S11 are the coolest Convoys.
Anyway , I’m still waiting for my Convoys to arrive so I’m kinda calming down.
