Rey's Titanium X6, re-make

Dale…please be careful. You could steralize this side of the planet with that X6 :open_mouth:

Gonna point it at Houston first, if that works I may well be onto something… :wink:

Hey db, i am new here… is that light for sale?? The 8000 lumen triple xhp 50.2. Lmk thanks.

Newlumen, no, afraid not. It’s kinda special as it was a Custom that Rey had produced. I’m a titanium nut, so with the X6 being my favorite light and this being a small run in Titanium from a member here, well, it won’t be going anywhere.

Testing it outside tonight the sheer output shone on the sides of railroad cars over 1200 yds away. And it would appear I fried a Trit vial. One of 2 green ones is now not illuminating. No visible damage, it’s just not glowing any more. It fires up green under a UV light, but is otherwise dark. These are like 2mm x 12mm in the head. There’s 10 of em. Yeah, I know. The trit vials cost as much as the Ti host did, nearly. There’s a 1.5 x 6 in the tail cap.

They’re very delicate, crack easily and the gas escapes, even through the glue.
Too much heat :smiling_imp:

Triple XHP50.2 wowsers!
this must be a difficult situation, either blow 10K lumens or have trits glowing for a long time.

I’m not suggesting anything, but Cutter has K2 bin in stock :wink:
I guess a wider opening is not reasonably doable in this host?
Could you share some more pics of the interior?

Just did some calculations based on djozz tests of XHP50.2. Getting the exact numbers from his chart is hard, so the results are not great, but I got 10893 LED lumen. Are the numbers that you quote LED lumens or OTF lumens?

My numbers are out the front, from the assembled light. On this one, the numbers given were at start on fresh charged cells. Many people argue that this is misleading, but when you’re pulling 15+ Amps from a 650mAh 18350 , well, it’s a very steep slope. (24.41C…Yikes!)

Wider opening? The head takes a 35mm optic, it was made for the CUTE-3 with a 32mm Noctigon. This X6 was made as a host and the buyer had to finish the build. I want to disassemble it and use some thermal compound between the copper pill and titanium head, so I’ll get some pics (should already have some from back when it was bought but I’ve got so many pictures I’m not finding these somehow…)

Much as I’d like to go with the next bin up from Cutter I probably won’t be shopping at Cutter anymore. After spending $25 DHL shipping to get a dozen XP-L W2 2B emitters and having V6 1D arrive in their stead, and nothing done about it, that was it for me.

More images posted in the OP. :wink:

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… :wink:

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. :wink:

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 :smiley:

Do you know the part nr on that khatod optic?
I got the urge to build something similar in a C8
