Still have the Fire puck below for my daughter but built this today out of crap I had laying around. The driver I'm using is Mattaus's RGBW 1x7135 driver which I already had a set of on hand (our FW's are both on the same 12F617, I used them for testing the FW without the CC circuit of my driver), I'd post a pic but this host takes a 20mm driver so the 17mm RGBW board is piggybacked on top of it hidden inside (I used a bare old version BLF20dd for the contact board). It's nice building a light that wont ever run above .7A so the GND path doesnt need built way up.
Unlike the Gen2's in which you can connect a single side to +, cause all +'s are on one side and all -'s on the other the gen 1 XML-C has alternating set's of pad's each die needs its own +in so thats what all the red wire's are on top of the sinkpad
I like how the light feels, always have but I dont use this light much at all, never carry it (it was a dedomed XP-G2 with a 12x 7135 driver and a ramping UI I use in all my zoomies)

Zoomed in fire, red is on the brightest followed by green flickering the most then low white
it also has a full spectrum fade (what this is, on a purple color zoomed in) and a steady white
I made this up this evening for a school project for my 9 year old (who just told me about the project tonight, its due tomorrow). This started out as a amber and red XP-E but I accidentally blew them testing hooked straight to a battery so I put this together. It's built out of an old gen1 XML color, the very first ever pukelight driver and a little puck of copper disks. Each color (blue isnt used) run's 1x7135 each but the highest the PWM used is around 200 and on average a good amount lower, after measuring the average current over a minute it works out that a 16650 should run for about 3h and an 18650 around 6.
I'll be throwing a few more together, only have one more of these boards but I have a few 17mm RGBW boards that Matt designed using this same 12F617 (also the same MCU used on RGBW_Clicky and pukelight, this code would work on my RGBW transistor driver to but why when I can use simple 7135's) so I'll also be throwing together a P60 and we'll be lighting all our pumpkins this year with "LED candles". I know this is to short of notice for anyone else (except maybe Matt) to get one of these together but maybe you can keep it in mind for something else.
The build was super simple, it wasnt planned at all, just sort'a thrown together, first I had the board glued to the PCB and it was impossible to reflow MCU's on and off cause of the excellend heatsinking, what a pain that was, but it doesnt get hot at all in operation so thats nice. For the past week we've been lighting out big pumpkins up with MELD lights but I dont like leaving them outside, this is <$10 worth of parts, who cares if something happens to it (or my daughter looses this one at school).
The code is from everett, I emailed him about 6 today and he had exactly what I needed (it does some other cool stuff too but its all commented out so my daughter cant mess it up). I dont know if she'll get an A on the project or not but I know for sure this is the more over engineered project her teacher's probably ever seen lol.
Not pictured the emitter has a white 20oz bottle cap over it as a diffuser
