Swapped in a new lens on my Jetbeam TCR-01. The old one was cracked at the edge from when I’d put on the bezel too snug.
Unfortunately, I didn’t measure the lens before ordering replacements. Ordered a mixed selection of 22mm lenses when what I really needed was 20mm. Whoops! 
Fortunately, one of the lenses I ordered was UCLP acrylic, which I was able to file to the correct size. 
Pulled the White Flats out of the little M1 I built yesterday, will apply them where they can be used for throw like they oughta be. 
I stuck sliced LH351D 80 CRI 5000K Samsungs on a different T-Pad board and used them. They make around 2500 lumens with a larger hot spot and nice neutral to warm white beam. More confluent with the big copper pill under em, works for me. 
And much less current I hope?
15.25A on a fairly full 30Q. 2660 lumens.
The efficiency difference is not day and night then (about 25%)
sorry 808 was a typing error
I also found out today the MOSFET on the driver is a faked one, not original SIR800 some sort of chineese copy
I have measured the FET used on the red MT09R driver
its labeled like the original Vishay cant tell any difference
@4.7V Gate
I got 38.3mV 10A —>3.8mOhm resistance
@3V Gate
I got 165mV 10A —> 16.5mOhm
@2.5V which the original should have around 2.8mOhm as its gate voltage gets very deep till 2V pretty stable
I get only 2A with reasonable input volatge and the stunning drop on the FET of 1.1V
so here the FET has 550mOhm
Conclusion
the FET HL use is definately some sort of fake which wont work on any 1S driver well
with 4.7V on gate it has a usable resistance but still this FET is like the MCU fake
this is just the Turbo static power loss on 60% with switching losses this may be even more depending how fast the FET switches
the bad resistance on lower voltage definately points on a lot longer phase where the FET is not fully switched through
Well you have to consider though Jos, de-doming/slicing takes a toll on efficiency as well, so the normal Samsung emitter would fare better it just won’t fit under this Khatod optic cleanly. This is made for XP-E I think, the opening to each TIR is shallow and quite small. It’s a 24mm 25.4mm Optic (PL115106, narrow) with it’s legs wider than our standard quad boards, the only ones I’ve found that work are the T-Pad’s because they have an open slot instead of a hole.
They say it’s a 10º, tested with the XP-E and compatible with XP variants and the XP-L HI.
Yes, the optics will add to how much light makes its way out too, the LH351D has a bigger die even than the XP-L HI so a little bit of the light may get lost in there.
The full copper heat sink may help to keep the light “warm” if there’s losses in the optic, that fresh copper orange color may influence the beam. Looks good, actually more neutral than the same (domed) emitters in my X6 Triple under CUTE-3 optics.
Finally got back to doing a few mods after being sick. Not much of a full post but I may take some measurements and edit it in.
Put MTN’s new 20mm boost driver in a ThorFire C8S. My first XHP35 mod. Sure enough I got the polarity backwards on the reflow cause I just assumed which caused me to waste 45m checking connections when the light didn’t work. You better believe I just switch the LED wires at that point.
Side note, this is a never used XHP35 HI on the bottom, what’s with the charred look? Both of mine were this way. Guessing it could just be oxidation lined up right where that hole is in the reel? They are pretty old.
And also there was an Amazon sale on Tool AA 2.0’s so I decided to get one and put a shaved dog fart (aka; LH351D 5000K 90CRI) in it and a BeCu tail spring just cause. I think the beam turned out nicer than I expected on this mod.
I have seen that little dark spot on so many, always assumed it was something to do with testing, how they bin them. Gold plated contacts right? Gold doesn’t tarnish…
The C8 with a 35 and RMM boost is an exquisite build, I get right at 2000 lumens in mine and it’s awesome!
Nice slice on the Sammy, neat little light for sure…
Yea it’s a neat light and the middle modes seem pretty solid. Turbo gets nice and hot without stepping down as quick as my 17mm boosted M1
I feel like it could be slightly focused better. Not sure what ring I need or change to make though if the beam widens too quickly.
Emitter swapped my modded Eagtac TX25C.
The TX25C is a small and lightweight thrower
Mine now sports the following mods:
On a fresh Vapcell 800 mAh 16340, I measured 60,000 lux (489m beam distance). Pretty nice throw for such a tiny light.
I buy from Clemence shop (forum member). Probably its because the driver its only 1,5Amps at max :+1:
I have a lathe because of Old Lumens. Justin loved working on Maglites, and I had a purple 2D sitting here wanting attention. So yesterday afternoon I did my first ever ChicagoX style Maglite 1D mod.
This is a “hard way” to do it, but the results net the smallest possible 1D Maglite. The top end of the battery tube is cut off and threaded inside to accept the tail cap, flipped around, the tail end is cut off and threaded for the head to screw onto. I have yet to fit an Omten switch in the tail cap and finish the build, but I have a couple of options I’m looking at. I have a TIR that is made for miner’s lamps, called Crystal Mine. It touts a beam angle as low as 3º. So I’m thinking about a White Flat with the Crystal Mine.
It dawned on me this morning though that I have an MCPCB and reflector from a Q8. So now I need to check to see if this reflector can be mated into the Maglite head. If so, I’m thinking about using it and slicing/dicing 3V 50.2’s for some 15,000 lumens in the stubby mag.
Gotta check, we’ll see….
Those are some serious fins!
Got the Mag pieces all cut and fitted, have to build it now. Using the MCPCB and quad reflector from a Q8. The Te/Cu pill is 291gms all by itself! Think I missed a trick, probably have some more work to do… made it to fit a Trustfire 32650 but totally forgot to remove the protection circuit first! 
Protection circuit?! We can’t have that now, can we? :smiling_imp:
And I was thinking that it was a sharp looking blue Mag… but purple, you say? Like I tell my wife, just don’t tell me and I won’t know any better! :disappointed:
Under fluorescent lighting my phone makes it look really pretty blue, but it’s a vivid eye popping purple. lol
The protection circuit limits this cell to some 7.2A, take it off and the cell rocks! Would you expect your Q8 to perform nicely with only 7A? Yeah, it takes more like 15…
