XML\XPL will give you a larger beam & more lumens, possibly at the expense of a little throw.
I'm yet to try an XML in this setup.
I did some calculations and according to my approximate results the āsurface brightnessā( I dont know if that is the right terms) of a xm-l2 driven at 6 amps is virtually the same as the surface brightness of a xp-g2 driven at 5 amps and even higher if you push the xm-l2 to 7amps. But these are just my assumptions based on graphs and readings made by other members Crash-testing a XM-L2 and a XP-G2 on copper Sinkpads
Could you please measure the current to the xm-l2 and throw readings of the next setup and take a beamshot for comparison??? Thanks!
Is there any driver capable of delivering 7amps to xm-l2 emitters? Does anyone actually push them so hard???
Sorry for a little off-topic, I dont want to hijack your thread, we can discuss it in my thread and keep yours clear! my thrower project- work in progress
No problem, weāre all about OT hereā¦
Iād like to build up another one with XML/XPL, but that may be a little while off.
The problem you are going to find, as I alluded to in your other thread, is finding an XML/XPL that will cope with those current levels.
Thereās plenty of drivers that will do it, but you are going to have to mod the D01 for a serial setup, which is a fair bit more work as well.
You donāt need a XM-L2 that can take hi current like the old ones. the new XM-L2 U4 is much more efficient, so even with the lower current use it will still out throw the lower flux bins that can take more amps.
I built a UF-1504 with the XM-L2 U4 1C dedomed, that i run fully DD without any driver at all. and it is much stronger (almost 1/3 :laughing: than my 1504 with a XP-L V6 1A that takes more amp & get much hotter but is weaker than the new U4 
And johny723, check out n10sivernās test of the newest high flux bin emitters in the 1504 to see there potential 
As you can see the XP-G2 S4 2B is even stronger, but with a smaller spot & less lumens.
Yep, it would be good to see some graphs/back to back tests done on these new U4ās / S4ās, compared to the earlier emitters.
I have another big KD reflector in-bound, & am thinking of putting it in different host, with a buck driver setupā¦
Nice, looking forward to see the host you are going to pick, i hope its a cheap one
It seems that 750kcd would be piece of cake for this light with newest bins.
That KD reflector is probably used in Eagletac M25C2 Turbo.
An excellent light for mountain rescue crews.
as well i dont like to cut the original bezel/ring , i dont know if this : http://www.ebay.com.au/itm/291553614311?\_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
will make the trick.
That looks as though it would do the job.
we will found out in 3-4 weeks
an update the ring above worked fine BUT after my second attemp failed to remove the extra material from the reflect (i ended up with 2 damaged reflector) we need to find a source pre-milled reflectors,its not easy job to do it without the correct hardware 
Sorry to hear that. It would be great to source an 86mm I.D. hood, then it would be a very easy mod.
I have one of these Courui on its way to me. I had a look at Kaidomain and see that they have two 86mm reflectors listed.
If I was going to attempt this mad mod, which reflector would you recommend?
Thank you
that would be nice but i dont think exist one + i think i might need another lense as well.i emailed kaidomain if he can source this lense without the extra material will seeā¦
btw FmC you used a drill isnt it ?
lampyris, i think they are the same.
I recall seeing two listings, & I think they are the same, however, this is the one I have been using.
Yes, similar style drill press to what I have. I used a high speed milling bit which I sank into the wood a little, then carefully ran the edge of the reflector against it (3rd pic in the OP of this thread).
Thanks for the link.
finally i manage to remove the excess material by hand, from the reflector without damage it .used the camera pieces you used and a the monster is awake.
now i am reading your post about focusing since i am using a hoop centering ring which is 1mm height,i think i should make it 0.7mm to see further gains.
Wow - must have taken you ages to do by hand!
I got in a OP version of the 86mm reflector, & trimmed it down just last weekend, & I was thinking āthereās no way I would be filing this down by handā.
I put the OP reflector into the L3 I modded a while back, & swapped out the XPL with an XHP 50. Turned out really well.
Are you planning to use XP-G2 in your Courui?
yes i am using xp-g2,i saw as well the other monster you create ,the reflector in photos looks more smooth than OP.I am guessing your next project with KD reflector and XHP35 HI will be http://www.banggood.com/COURUI-D07-CREE-XHP70-4Modes-5000LM-Super-Bright-LED-Flashlight-18650-p-1075199.html
That was the SMO reflector still, in that thread.
Here's the 86mm OP reflector installed, with the XHP50;
I hadn't seen that big Courui you linked before - would make a very nice host, but a bit pricey
