I was quite pleased to find HKJ’s review on the little Aspire 18350 cells recently. More capacity and better discharge rates in these half cells mean a lot to me. So, looking at the first thing I wanted to improve with them I kept coming back to my Titanium X6 from Rey. I have it loaded with trits so I can’t flame anodize it, but perhaps I can go about it another way…
I ordered 3 of the relatively new XHP-50.2 from Richard, already had a XM-L footprint triple 32mm MCPCB from Cutter, and already had a Khatod optic to fit it. (The Khatod has openings large enough to fit the XHP-50.2 without a dome slice. ) Looking at how the stack would align I needed a few extra millimeters under the MCPCB. So, instead of just putting copper under the board I made an entirely new pill from Tellurium Copper. That 3mm taller to aid in the spacing and thermal properties. Built up a 17mm FET with 8.4V LVP, and today the emitters got here. Not one to wait around, I built my first X6 Triple XHP-50.2! The emitters fit beautifully into this Khatod optic and everything seems to work fine. Charging up an old pair of light purple Efest 18350’s to get a general idea what this bad boy should be capable of, waiting on my Aspire 18350’s to arrive… they’re en-route.
Here’s the new pill, next to a spare one…
How does 7693.5 lumens sound on the old pair of cells? Holy smokes! By quite a margin the most powerful X6 I’ve built so far! lol
Edit: On the newer dark purple metallic looking Efest 18350 I got 10,315.5 lumens at 15.87 Amps!
A top view of the 3 50.2’s inside the Khatod optic…
A quick tail amp check showed 10.41A from the old pair of Efest 18350’s, the new Aspire’s should do better and with nearly twice the capacity as well. I won’t be at all surprised if the new cells push this up over 8000 lumens.
More when I can…
Edit: A few pics from when the light was originally built, August 13, 2015…
I’m a Ti Freak, and the X6 is one of my all time favorite lights, so this was a birthday present to me, from me.
Edit: I had forgotten to engage moon mode by grounding pin 5 on the driver, and I felt like 10,000 lumens was too much in this light so I wanted to reduce the wires to 22ga from 20ga. I opened it up and was going to pull the pill so I could put thermal paste in for a better contact but it had swollen with heat and simply wouldn’t unscrew. Ok, forget that part. I replaced the wires with 22ga, then when I put it back together I crimped the edges of the copper onto the driver to hold it in snug and prevent it from rotating when screwing in the battery tube. Added some solder to bridge driver/copper and ensure my ground was solid. Reassembled it and now I get these readings…
0.05A for 29.12 Lumens
0.19A for 155.6
0.44A for 455.4
1.33A for 1283.4
5.46A for 3774.3
11.35A for 6865.5
17.22A for 10660.5
Well, I tried! lol
EDIT: Not being one to leave well enough alone, I tried my new pair of Efest 20700 cells on this Ti X6 50.2… had to remove the battery tube of course. So, with this kind of result I may have to make a new 2 cell titanium battery tube!
13,558.5 lumens, out the front. Sick, I know…
EDIT II: Sorry, the cells were at 78% on that 13,558.5 read… after a fresh charge on the 20700 Efests they give 27.84A for 14,283 lumens!! Just stinkin insane!
