Wow!
Lol, thanks guys. It’s a journey for me too 
In fact I need your help now. Mechanical stuff I can usually get my head around but electrical…. not so much.
I soldered it all up and plugged in a 30Q. The tail switch lit up but was dimmer than previous tests. I didn’t think much of it at the time (maybe the cell was low voltage or something…?). Hit the switch and… nothing. Tail light goes out but no action up front. A bit of stuffing around to discover the brand new xpl hi was not working. Swap in an old salvaged xpg2, of course I checked to see if it worked beforehand, only to have the same result. No insta-flash, just a half dim tail light. I’m thinking it’s impossible to have a short the way I had wired it up but I’m at a loss to realize what’s going on ??
So can anyone explain or guess what might be going on? 2 leds gone poof and I can’t work it out.
Looks like an XHP-35 HI to me, needs 12V. Touch direct leads from a cell to the pads and see if it lights up, or just touch it with the continuity probes from a multimeter and see if it shows a dim light. The XP-L HI can take some 6.6A so unless you have a 9A or 12A driver there the emitter should handle 6A if indeed it’s an XP-L.
The XP-G2 might have fried from too much current.
Make absolutely certain there are no single wires touching anything on the board from those emitter leads. This driver has a lot on it really close together and a short on the board can happen. Eyeball it with magnification if possible, an aspheric lens works well for this….
Yes, I previously tried the multimeter probes on the xpl and it worked. Tried again after being installed and it didn’t work. Same thing happened to the xpg.
Almost positive though that you have a 12V emitter in there. 
I’ll have a look with some magnification see if I can see anything 
Would a multimeter light up a 12v led?
There is too little white substrate showing around the die for that to be an XP-L HI. The XP-L die is smaller than an XHP-35, more white substrate should show. I’ll try to get ya a comparison pic quick like…
OMG you are right Dale. I just powered the led with 12v and it worked 
Thanks mate. So the xpg possibly popped from too much current? So I need to program the driver before hooking up to the led some how….
Yep, the XP-G2 can’t take 6A, might do 5.5 from a buck driver but most 4.2V cells won’t push it to it’s optimum in a direct drive situation. Usually takes two cells and a buck driver to hit 5.5A because the Vf goes too high for one cell.
Hope I’m making sense, just woke up and no coffee yet…
Lol, of course your making sense. You haven’t had coffee and you already spotted the problem. Hats off to you 
And I’m sick. 
My Dr. put me on an arthritis medicine about 6 weeks ago and for the past week everything I eat has turned liquid and gone straight through me. Stomach has been knotted up with cramps. Not sleeping all that well waiting for a late night gastric explosion. 
Quit taking the Celebrex but stomach is still an issue. And my hip is going back out as the Celebrex leaves my system. Always something.
But still, an XHP-35 HI looks different than an XP-L HI.
LOL
Connect the driver to an XP-L2 or SST-40, turn it on and configure it to 5.5A, or maybe 5A (10 clicks, then 1 click, then 4 clicks… 4 is 5.5A, 5 clicks there is 5.25A, 6 clicks is 5A, then 10 clicks to escape configuration), good to go in your light.
I have my DBC-08 with White Flat set to 5A and it’s running great. About 760 lumens, reaches 610 yds so I’m happy with it where it’s at. Should run in the neighborhood of half an hour on the highest setting with my 16650 2500mAh cell.
OMG. Makes me wish I owned lath. Nice.
Okaay I’ve finally got it up and running 
(with some help from Dale 
). The tail is still dimmer than when feeding it direct power. I guess that’s got to do with the power running through the bleeder on the driver?? I’ll probably do an emitter swap at a later date but for now I’m calling this done 
Before and after blackening
The jax blackener is not really wear resistant. After a few on/off’s with the bezel you can see the black is starting to wear off.
This led and reflector is kind of a throwy set up. The wall is about 3m away. When white wall hunting I can see some artifacts in the hotspot but I think that’s mainly due to the dirty led that I resurrected.
Nice detective work Dale.
pp. Stop white wall hunting before I come around and clock you with it. 
Clock me and run off with my light, more like it…
I took some pics after the sun went down but it’s hard to catch it in the right light to show it off.
One thing I really like about this light is the bold contrast of colour in the pattern. Compared with my 7th O-L contest entry in the next pic, the copper in the superconductor has naturally patinated faster than any other copper I have owned. The superconductor pattern is not as obvious as it was when freshly cut.
Love how that came out, very unique and brilliantly planned! Steve won’t come near it, don’t worry about that… he’s too scared you’ll nab his driving lights! Lol
Great work from down under lately, you guys are really steppin it up!
Amazing light! If you hit the lottery, you can add jumbo tritium tubes, or just take the money and buy a yacht
