I’ll find out tonight hopefully, only finished it at half ten last night and mrs gords was feeling neglected I think. I suspect it will shed the heat pretty well though, the heatsink is 55 grams and it fits the heads threads very well after scraping out the threads, there is a lot of surface contact between heatsink and head.
under test, two minutes in, fins warm to touch. two year old flashed daddy on turbo, daddy now has huge purple 3 leaf clover pattern in vision…… :cowboy_hat_face:
LOL
Very nice light Graham, congrats
seven minutes in, fins hot to touch, body tube warmed, batteries above lukewarm. This is in an 18ºc room tailstanding with no cooling on turbo (direct drive) @3.8v per cell I was seeing 3.2a at the switch, I expect it to be closer to 4a+ at 4.2v/cell (charged cells last night, they are somewhat fresh this morning), I will do further current tests tonight hopefully, but its my dads birthday (built him a cnqg d1 3a 3mode xm-l 4c for his birthday) so I will be tied up till later on.
this thing is awesome spas, my customer was hellish impressed when I turned it on in the back of the van, he carries an incan mini mag lol, its a touch brighter than that.
LOOKS really good G
Bwaaaaahaaaaahaaaaaaaaaaaaa !!!
He could bundle 300 of those together, and yours would still be brighter...
Sweet build!
Happy to have been able to provide a tiny bit of the equation, but clearly the hard work was put in by you and ChiX.
And this is a good push to get me off my #$@# and build the almost-twin to this one. (Same host, PilotPTK driver/emitter, plus an absolutely excessive heatsink…)
Looking forward to a few wall-of-light-shots.
Here are a few more pics of the heatsink:
New one on the left, next to the original hollow version:
IIRC, the original one weighed in at ~19 grams. This one is a bit beefier:
Nice job. The best of BLF comes out when members collaborate. I like it!
What a sweet sweet light! Great job done by all involved. 8)
cheers for posting them chi x, I’d probably not get around to it tonight, dad was well impressed with both this and his birthday light.
my customer was also very impressed, he’s a nice old guy and always interested in what I’m up too, he just kept saying “god, what they can do nowadays” then clicking the light back on and chuckling. 
Wow! Nice build gords! Glad to see the group effort involved! Long live BLF!

I’ll be honest, for me, all credit goes to Chicago x, I merely assembled the kit he created. I am though very pleased with it, this is one build I’ve wanted to do since I read chicago x’s post.
very nice!
beamshots, phone camera so take them with a pinch of salt.

the glow to the right is spill from the light, had to hand hold and operate the camera.
Wow! Nice beamshots! Esp for a phone!

its not bad, I need to find a flashlight beam shot camera app because none of my shots capture the spill properly, there’s a huge building behind the tree, this light lights up the whole damm thing but I cant take a picture 
This one’s a little late, but I figured better late than never.
So, the backstory: Nitro was selling off some nice hosts. ChicagoX had done a couple of builds with that host, so I approached him to do a heatsink for me. (Somewhere along the line, poor Gords got suckered into a host and some ChiX magic, as you can see above.) Chicago’s build thread is here: Xmods: PilotPTK Neutral-White Triple XM-L goes into the CNQG Extreme Longrun (REVEAL)
Happily for me, I ended up with a the host, a PilotPTK emitter/driver (NW), a Cute3 optic (9 degrees, maybe? I’d have to check), and some awesome ChicagoX machine work: an optic retaining ring as well as a pill to be reckoned with.
You can scroll up to see the stock pill… this is what I got in the mail:
(for those that don’t do grams, that’s about 1/2 pound of copper!)
Fully loaded, this is a hefty bit of kit:
I won’t actually talk about the build, as the heavy lifting was really done for me by ChicagoX, PilotPTK, and some anonymous factory worker in China somewhere, but the results are absolutely amazing. This thing puts out a wall of light. My backyard cringes if I go near it now. (I used to think that 1400 lumens was something special; that’s all changed now.) I’m sure there are beamshots around, but I’m also sure they don’t do justice to this light.
So, hats off to ChicagoX for the pure craftsmanship of your lathe work. (If I was wearing an extra hat, I’d give you credit for quick work and shipping as well.) PilotPTK, your functional jewelry is appreciated. Nitro, without you, I wouldn’t have laid hands on this host. Thanks to you all.
not sure how i missed this thread but you guys did an outstanding job on this host. i am truly in love with the light. rock on!
