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).
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.
Look in the Convoy store on AliExpress.
There is a 3 mode buck driver there, and could well be resistor modded without heat problems to 4 - 4.5 Amperes.
It is a double PCB diver, but no parts on the bottom PCB.
I think it’s around $ 6.
Complex little driver! I just put a 6A LD-A4 in an Eagle Eye X6 host that came in today. I soldered two 20mm copper boards together for height, used a 35mm TIR with a deep narrow “cup” over an XP-L HI and connected these with 20 Ga Turnigy leads. Set up for 5A, with 4 levels and moon mode engaged it works pretty nicely.
The large TIR will show it as unique, the LD-A4 guarantee’s it.
I honestly have no idea. It was in my kit, appears to be new, was in the black plastic holder and I had to remove it to fit into the bezel of the X6 which was a little tricky. Works pretty neat…
I have bins and bins of bits from Justin, as much or more than what I already had of my own. His stuff and my stuff together makes for a LOT of stuff! I can’t remember my own purchases, still finding things in his stuff that I didn’t know I had.
Y’all just can’t know, it’s like he’s here with me all the time.
Bittersweet, at times. Uplifting in other moments. And so it goes…
