Huh, same thing happened to me! Same XP-L W2 2B crap, V6’s instead. It’s a big cost hit to take, plus the wait….never again….done with that BS!
Really cool pics of your light Dale! :+1:
Thanks Kawi,
I was thinking, with the pair of half cells, that it would probably do something like 6,000 maybe, a bit more? Boy was I surprised! It’s too much, of course, for this size light… even with the chunky copper pill. But then, there are all those other mode levels I suppose…
Yeah, it was neat that Cutter had top bins and components you can’t find elsewhere, like the Khatod optic in this build, but if he’s not going to ship what you’re buying, and not going to fix an error without it costing you even more, well, just bugger’s up the whole deal. I was willing, and told him so, to buy another dozen and just keep the V6 1D’s so they wouldn’t have to be shipped back. All he’d have to have done is pay the shipping on the correct dozen emitters. I probably even would have let him use the cheaper shipping method, but …
Damn thats a purty host
Updated pertinents at the bottom of the OP. I switched wires from 20ga to 22ga, also soldered star 2 for moon mode. Actually increased ground and got better output even with smaller wires! lol Ok, so I’ll have to avoid level 7…
This build could probably be done better on an aluminum Eagle Eye X6 host. The Khatod 600 series optic is 35mm in diameter with an 11.8mm height so it’s about 3.2mm shorter than the CUTE-3 I’ve used in the past. The key to this optic is the wide opening that allows the XHP-50.2 to be used with the dome on. The extra 3.2mm height required for a copper spacer would be utilized to an extreme with the power this puts out. Richard has the Cutter T-Pad 32mm triple XM-XHP-50 triple MCPCB, as well as the emitters. He can also build the Zener modified FET to drive it on 2 cells.
I opened up the tail cap slightly to allow the back cell to fit further up into the tail cap and alleviate some spring pressure, also allowing the tail cap to thread on all the way. Similar can be done on the Eagle Eye hosts fairly easily. The legs on the Khatod optic have the post too long through the board, I filed those down to fit smooth on the back of the T-Pad board and it works out well. I supposed a standard spacer could be used and two extra 32mm Noctigons (or T-Pad’s) could be added under the main one for that 3mm stack height increase. Should be easy enough really for almost anyone to do it.
It’s an astonishingly bright build, looking forward to seeing some others give it a go and get their impressions…
Any hint on the source of discrepancy?
Heat?
Haven’t calculated that before…147 seconds until battery drainage. Though I guess at 120 W it would desolder before that.
Discrepency? What discrepency? djozz sets a C8 reflector on top of the emitter while it’s on a large heat sink and being driven by a power supply. Lab results, not real world. My numbers are in the flashlight, running on batteries, with an optic over the 3 emitters as run through an Zener modified FET driver. Not the same test at all. Not to mention a very large difference in equipment. djozz has some nice finds for his meters that would be difficult if not impossible to run across on demand…
You never cease to amaze me with what you can build. Hope your surgery went well. My mom’s had back and neck surgery I know it can get rough.
He has a more capable setup without optic and gets marginally better results. After substracting optic losses your light does ~18% more than my calculations predict. That’s why I asked if the results are OTF, your reported result was much closer to calculated LED lm then OTF lm.
That said, djozz doesn’t mention cooling the LED down between measurements, so I suspect that his LED is hotter than yours and that would be my first guess as to the reason why your light fares better. There might be some testing / calibration variance too. And my reading of the graph was rough which affects results. I wanted to know if there are other factors that could be at play…
Oh wow thats bright 
Do you know the part nr on that khatod optic?
I got the urge to build something similar in a C8
+1……… nice pics of an amazing light. Thanks for sharing
Very nice!!
Doesn’t these Cutter guys know who you are? Strange manner of acting, maybe link them to this topic?
hahahahaha Miller, that’s hilarious! I’m nobody, sometimes even less than that.
Tj, the part number is Khatod PL605A06, I found it HERE at Cutter. I’ve had this optic sitting here since the late part of 2015, used the first one of two I bought in a chopped MagLite. (ML25XL or something)
It’s 11.8mm tall, so about 3.2mm shorter than a CUTE-3 from Ledil. Just keep that in mind…
Thank you! 
I wonder how long until sb. makes a run of spacers for this build.
BTW, this is just a few mm too large….would bring efficiency up a notch. I guess there’s no readily-available host though?
You never cease to amaze, Dale!
Agro, that optic is designed for 1mm die emitters like the XR-E, they are array type that are made to interlock together for a light fixture such as a street lamp or overhead lighting using large numbers of series emitters with very low amp draw. According to the chart listed there, the beam profile of one of those would be around 30º or in other words, very floody.
JM, surprised me too! lol I was thinking maybe it’d do up towards 5 or 6000 lumens, even limited the wire size in order to try to keep it real for heat issues. With the 2 small cells I sure didn’t expect those numbers… and have better cells coming so we’ll see if it makes much difference there.
