Thanks Djozz! Nice to see some easily comparable graphs. Always nice to see some graphs and hear your thoughts.
In the future, could you make the 4,5-9 volt range easier to compare when testing emitters in this voltage range?
Do you plan on testing 6v vs 12v configuration some time just to see if there is any difference?
Thanks also Djozz. It was remiss of me not to comment. Appreciate your hard work as usual.
I'm not sure what you mean, perhaps that the scaling of the voltage axis can be changed so that the voltages show more accurate? I do not usually do that because then the voltage curves get in the way of the light-output curves, that is why I choose an extended voltage scale, and I choose a max so that the scale fits into the grid that is dictated by the light-output axis. But I realise that the voltage scale does not necessarily have to start at zero, that makes a variant possible that shows the voltage better and still does not obscure the light-output curves completely, is this a better graph?:
Your latest version is great. Much easier to read. :)

Hmm, I didn’t see the difference in the shape of the Vf plot for MT-G2 vs XHP50 and XHP70 before. (It was there, I just didn’t notice.) It took me a minute to see why they are different. The XHP50 and XHP70 characteristics are compressed on the X-axis vs the MT-G2 because they peak at a lower drive current (in this test at least, maybe things will look different for the XHP70 if djozz is able to test again on a proper MCPCB). That said, I think the shape of the Vf curve may still not be exactly the same. It’s at least a little interseting to me.
At a tail measured 7.45A I’m showing 4426 out the front. Considering the small reflector and the nature of the reflector, the losses from that chart make pretty much sense.
You guys need to pick up the pace with the modding. I’m hankering for a sub $100 16,000 lumen quad XHP70 beast!
Impressive observation Dale 
you're right, I did not have a clue about the polarity of this thing at first, the next reflow of the XHP50 I noticed the symbol on the back. So I guess you looked at the direction of the bond wires on my picture..
The 4 bond wires in a row are on the positive side. The little symbol on the bottom is a horizontal line intersecting a vertical line (actually a T on it’s side with the horizontal pointing towards positive)
Data sheets are invaluable. 
First shot is the X6 with XHP70 and the new FET Zener modded driver.
Second is the X6 Triple with XP-L V5 2D. I have to correct what I said earlier on the emitters in my Triple. The V6 2C’s are in a different light.
4400 lumens as compared to 3500 lumens. The triple is still the more usable light, in spite of pulling higher amperage. The XHP70 at 7.45A makes some pretty serious heat, pretty fast! And the triple with the CUTE-3 optics has some beam profile to it, with a center spot when seen closer. This XHP70 only has a “hot spot” inside the house at 10-20’ distances.
I'm waiting for that tree to catch fire one of these nights. XP-L still looks sweeter.
We can track LED development by watching the tree dry out in each new picture Dale takes, and the one that sets it on fire will correspond to Cree’s peak stock price. 
And that’s with the Minnie-M, the tightest Minnie?
This sits on the heat sink like the one for the triple that Nitro is having made.
The CN10861_IRIS is an Optic that looks like it will sit right on the star and work without it’s holder, no heat sink or anything else required. I don’t have that one mounted in a light as I am out of XHP70’s to try.
Talking about the Eagle Eye X6 as a host still.
Thanks, just making sure I had my facts straight!
that xhp70 x6 has a nice beam profile. very smooth and floody with wide spill. it could use a dedome though….
heheh
Great work DBCstm. It looks like you found a great simple mod for the X6. The Iris should provide a good increase in throw over the Minnie-M. Especially since you had to cut the Minnie to fit.

The Iris for the XHP-50 looks even more interesting and should also fit the host.
Mmm, FlashPilot I think the Minnie-M did not require cutting: that was the Mirella.
Ah, thanks (and edited). Either way, it would be interesting to see how the Iris performs. More throw for less flood.

Taking some measurements, 3 x Iris reflectors will fit inside the BTU Shocker with some room to spare. Now… how to extend the battery tube for 2S3P. Darn Rick for not listening to me. OL… HELP!
Thanks Dale & djozz for all the testing, very interesting and so fast i can hardly keep up
