So it’s been about 2.5 years since I started this thread and I haven’t been very active around here for a while! Life has taken priority with buying a house, getting married and going on a long trip to the US for our honeymoon.
However, I decided to pull my finger out and get this build going again. The sad part is though, by today’s standards this light isn’t going to be overly impressive anymore! :cry:
Anyway here is today’s update:
I modeled the heatsink/spacer in Rhino
I then took the CAD file and my chunk of aluminium to the machine shop and this is the result:
A few more things which have happened:
- I’ve decided to purchase two BLF GT 4S battery carriers from Neal rather than modifying the factory ones as I think I will end up with a better result this way, it will be cleaner and should carry more current.
I have purchased some more 16AWG Teflon wire and think I will go with blue and transparent now
That’s it for now and hopefully the next post won’t take another 2.5 years!

Well, I have been collecting a few parts recently and the last of them arrived today.
They say a picture says a thousand words so I will just leave these here for now…
I have bought some 16awg silver plated teflon wire from the US which I’m hoping will carry the current ok.
Twin FET set up so the firmware controls both FETs and they run at predetermined %’s and the second switch will control the third driver which is there only as a lockout.
Are those Carclo optics? Dale recently found you get a lot more (apparent) light out of Khatod optics. Something to think about before you cut down your heatsink.
The Khatod’s are available at Cutter and the Cutter quad mcpcb is designed to accept them, it’s the reason for the slot instead of a hole for the legs.
Tighter beam, more output. Taller optic as well so the heat sink will be shorter.
Edit: Might be worthy to note I had a bit of issue with the Khatod quad over XP-L HI emitters. I had the HI’s in my little DBC-04 Titanium light and one of them got the bond wire broken by the very small opening of the TIR on the Khatod. I now have 219C’s in it and they’re working fine. Also might make note that when I built a Quad X6 with XP-L HI’s I ended up with less lumens than a 219C variant due to the lower Vf of the 219C. Something to think about anyway.
