Thanks for bringing these to us. Looking forward to put into the EE X6 and Convoy S6 with SMO hosts.
I know how you feel. I really want to do a full Led4power build (MOSX MCPCB, LD-4 driver, illuminated tail cap) because the components all look awesome, but I’ve got a pile of components I still haven’t used yet.
Still, the OSRAM KW CSLNM1.TG (catchy name) does seem like the perfect answer to the question of what to do with the two Cometas I bought recently…
I did buy some of the new leds despite the pile of components that I still haven’t used yet :person_facepalming:
(I admit that I have a problem, that is the first step, right? :innocent: )
Are any new products going to be added any time soon? I’m not sure if shipping charges are going to change any time soon…
Shipping fees should remain the same as they are now.
L4p what color do these new Osram leds have?
And when the spacers for c8 i x6 will be available?
Man the new Osram looks sweet. Too bad I already made an order from you last week. I will order some for the Cometas I got when you have the C8 spacers for the 6x emitters. Are you going to make a kit for the Sofirn C8F 21700? That seems to be the ideal light for this new mcpcb.
I sent some measurements to kiriba-ru for the C8F 21700 but you should express your interest to him as well. The C8F is e-switch and I suspect his e-switch driver may still be a ways off. Meaning, no “complete” kit for some time.
No complete kit is fine. With Sofirn’s revised driver (the first one had problems) it is still a very good driver and with 6x emitters, it will run alot more efficient if not a whole lot brighter.
The chromacity bin is: ebxD46. Looking at the Osram datasheet and plugging the coordinates into this website,
the CCT is between: 5849k to 6384k
Less cool than the Black Flat
Plugging the coordinates here:
the DUV is between: –0.0044 and –0.0043, which will at least ensure the beam will not be green, maybe it will be a bit on the rosy side. I like the pure white of the black flat. Hopefully this is about the same.
The flux bin is 6N
at 1A: min 315 lm and max 355 lm
Compared to the Black Flat sold on Mouser, which is 8M flux bin:
at 1A: min 250 lm and max 280 lm
Me too… :weary:
Still, boxes with plenty of parts are better than fewer parts. :innocent:
Maybe call them “White Flat” ?
Yeah, i just ordered 3 pcs…
They will find homes pretty soon though. 
I will put spacers this weekend, I'm busy more than usual, so there is delay for some stuff.
Is there any chance to have distance ring for standard reflectors and this new osram?
I don't think there is one, probably simplest solution is to rotate 3535/XP centering ring.
Just ordered 3 of them
Apart from the LD4A, are there any alternative 2S (buck) drivers for tail clickies that would be appropriate for the new Osram-LED? So far, this one here looks okay but it cannot deliver the required 5 amps of current.
The best would be a buck driver (2.9V - 8.4V), e.g. in a Convoy L2 (short and long tube) running at full power over the entire voltage curve.
MTN buck driver. But it’s out of stock…
I'm not sure if this one is for tail clicky lights or e-switch lights. It's also quite expensive to get these things from the US to Germany (shipping and hassle with customs).
Contact to your neighbour Lexel 
This type of driver is rare as a spare part. It’s probably easier if you just buy a used 2S light with buck driver (maybe a Fenix tk-35) and switch out the sense resistor to get a higher current.
For continuous operation I would go with 4A. I had problems after a while when driving a Black Flat at 4.5A for longer periods of time in a large host with very solid heatsinking.
The FX-35 driver in the Convoy L6 is a 5A 2S buck driver that’s also very, very cheap. I don’t know how well it works with 3V LEDs though. Normally it shouldn’t be a problem. It can be bought as a spare part from Convoy.
