As much as I want to own the current champ thrower LED, and put it in a light, I have to admit to myself that I have bought already enough LEDs, drivers, reflectors, and other components, and never did anything with them. They say the first step is admitting you have a problem. I’m admitting that I too often fool myself into thinking that “this time” I’ll actually do something with the amazing new technology that has suddenly come available, so I should buy it before somebody else does. :money_mouth_face:
Well, I’m not gonna do it. I’m going to leave these amazing LEDs for the true modders, who will make use of it. I will be amazed at their creation and wish I had it myself. But it won’t do me any good, because I’m too lazy to build it. :weary:
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: )
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
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.
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).
