kiriba-ru C8TT triple heatsink head build
Since kiriba-ru’s C8TT head is so unique I wanted unique parts to go with it. I opted for the highest CRI and highest lumens I could manage. LED4Power’s parts were the obvious choice, constant current + FET + moon + temp + good UI. I don’t think either of these guys get enough credit for the awesome stuff they produce.
- LD-B4 (12A CC linear driver) from LED4Power
- 4040 MosX board w/ FET & NTC
- 2x Luxeon MZ 3000K (>90CRI) + 2x Luxeon MZ 5700K (>90CRI)
- LEDiL CUTE-4 optics
- 20G wires throughout + bypasses
Brief tests & observations:
12 Amp Constant Current mode:
- ~2,590lm @@ 30s - VTC6 at 4.xx volts
Direct Drive FET (pulling 28.xx Amps!!):
- ~5,142lm @@ 0s - VTC5A
- ~5,112lm @@ 0s - Samsung 25S
It’s nuts this thing can suck up almost 30 amps from a single 18650 and still be >90CRI light

Reflow prep station, triple check your datasheets for anode + cathode time, thaw some 63/37
I saw on the datasheet a 7” steel crepe pan was recommended. Yes I seasoned it, no I don’t use it for food. ($14 Amazon)
Too much solder paste, story of my life. Plz suck up a bunch when it gets to temp ::crossing fingers::
OK, I can work with that. Must be magic… For anyone questioning if you can do this. YOU CAN, it’s night and day obvious that it’s basically aligned and melted. Haven’t even touched it yet…
Remember how I said too much solder paste and anyone can do this? Everyone has to start somewhere, time to suck it up and cleanup your (solder) balls.
Time to check your work (fun fact, since LED4Power’s MosX boards have the FET on them this shouldn’t have worked. The modding gods must have left a little charge in the FET for me knowing I have no idea what i’m doing)
I wont bore you with my crappy soldering stories or trying to snake wires all over the place or mixing up FET and Temp wires but lets just say I got it done.
Time for the glamour shots:
will probably change this to a clear ano’d convoy tube some day
tint mixing is the new hotness, get on board. Inspired by maukka tests of two slightly above BBL LEDs mixing into a middle tint below BBL. Also, it just plain looks COOL in moon (<1lm)

and last but not least, obligatory beam shot from a cell phone on auto (you’re welcome)
There is a slight donut which surprised me from a TIR optic. Considering how well everything else turned out, I can look past it. I’ll try a piece of DC-Fix when I get around to it but I suspect I will miss my precious lumens and take it out.
