I put a 20ga spring bypass through the charger pcb, it had small coil springs on each side of the board, I put a slightly larger one on the battery side to allow the internal 20ga wire to coil slightly under compression.

Fresh charge on the little Efest V2 16340 gives me 2294.25 lumens. Works for me!

(for now) I have some 1000mAh 15A continuous Efest 18500’s en-route, I’ll make a couple of copper or brass spacers ( one on each end so the o-rings stay covered…even aluminum would work) and bore out the battery tube so the 18500 will work and the lumens output should go up considerably. Big Smile

Will post when I get that done, probably early next week. We’re at 25 and dropping, supposed to have maybe single digit temps overnight, yuck!

Edit: By the way, it looks like the little Efest V2 16340 is delivering 5.5A at the tail. The 15mm driver has one of the little 3 legged MOSFET’s on it. I can’t expect it to perform like an SIR800DP or something, but it’s doing really well so far.

Brass spacers? I’ll be interested to see how this works out:)

Yeah, like, a threaded tube but thin and cut short such that one on each end would space the battery tube out and allow a longer cell to work. The margins are thin, trying to be sure the o-rings stay covered so it looks right and maintains water-proofness, but it looks doable. I’m more worried about the battery tube being pretty thin bored for an 18mm cell, might just make a knurled titanium tube to replace the stock one so the 18500 cell works perfectly and things aren’t “fudged”.

I like the titanium idea. My childhood perception of titanium has varied well on into adult hood:)

I’m not a chemist but I did used to have fun with just #2 at birthday parties. You could read that a couple of ways but count me civil enough to know the difference Big Smile

When I was a kid I was small and quick. I loved watching Bob Hayes, #22 for the Dallas Cowboys, break away and leave everybody in his dust. Then it was Emmett Smith, also number 22 for the Cowboys, breaking records and becoming one of the all time greats in his own right. And some 20+ years ago I discovered Titanium. Lightweight and strong, #22 on the Periodic Table of Elements, and I became obsessed. I wear Titanium glasses, have had a Ti wedding band of my own make, Ti wristwatches, knives, pill fobs, key fobs with Tritium vial inserts, Ti EDC flashlights of my own make, you name it, I love it in Titanium.

Some 16 years ago my son talked me into joining Yahoo Chat. I was TiFreak2201, somehow that gave people the wrong vibe and I got a lot of comments. Go figure. For me it was innocent enough. I’m a Ti Freak, it’s PTE #22, and the year was 2001. In the end it all worked out, I met my wife within a couple of hours of getting online and we’ve been married 14 years now. Smile

Ever wonder what the next 22 will be in your life? Smile

You must have titanium fingernails to be removing those retaining rings! I tried now my nails are all torn up:)

They glue the driver onto a shelf, even gaining access through the switch hole it takes a couple 3 or 4 pretty good blows on a small screwdriver to bust it loose.

I glued it back in, potted the piggybacked 15mm FET in the process so it’s really glued in… not sure why I did that so quickly, I meant to stack a second small FET. Oh well, too late now!

Dale the PT16 V3 holds a 18350. If the charger is removed does it have the clearance for an 18490 or 18500? I know yours is the version 1 16340. I’m just curious about the length. So many chargers around the house 18500 over 18350 make more sense for me.

Mine that was made for an 16340 won’t house an 18500, the tube is too short. Hence the talk of making spacers for each end or making a new tube.

Haven’t seen a “V3”, guess I should look at MecArmy’s new offerings…

The rather short and stumpy pineapple knurled original is eye catching though, it’s so ridiculously small it’s just fun! Big Smile

Looks like Illumination Gear sells the V3 18350 size tube with tailcap for $20, 3 in stock at this moment.

Thank you for the head’s up, I hadn’t heard of either the site nor that MecArmy had the upgrade.

Will that tube screw onto any of the heads?

Thank you Dale for all the information regarding your experiences with modifying the PT series, Mecarmy should supply you with free samples.

LightRider, it should. I’ve had the PT10, 14 and 16 and they were all interchangeable. So say if you had bought the PT14 with 14500 cell and then buy this tube from illumination Gear then you’d be able to use the one head with either cell type, actually 3 cell types as the 16340 still works in the 18350 tube.

I REALLY want one of the MecArmy Limited Edition lights, but they’re insanely expensive, $1700 I think. The details are exquisitely rendered, amazing.

FWIW, my Aunt confiscated the PT14 and my wife took the PT10. sigh.

Wow! That’s not even CLF range!

Have you seen their limited edition’s? They look like Bamboo shoots, with the cracks and holes and knuckles where roots were coming out, darkened in the cracks and the knuckles are gold plated, the entire thing is done in Titanium. The detail work is incredible.

Takemitu = Take me too… it’s calling me, see? Silly

Seems like there were only 10 made of each one, worldwide. So I’ll never see one, as if I had that kind of money anyway right?

Ok, so by now y’all KNOW I really like the PT16, right? So I’m gonna get me a PT60 for sure, and if it makes 9600 lumens with XP-G2 emitters what will it do with XP-L W2 1D’s? Big Smile

Next couple of weeks….

Shoulda left well enough alone, just re-discovered the PT-16 in brass. OMG! Aluminum reflector! Geesh, why is it priced so high? Me want me want! lol (incorrigible I know.)

I got the 18350 battery tube in today from Illumination Gear, worked just fine although the charger portion was a bit different. Didn’t really matter as it came out anyway. I took the new tube and head out to the shop and bored the top of the battery tube where the charger sat so an 18500 could slide through all the way, then I made a couple of brass rings that would fit around the cell and act as spacers top and bottom, 1.2mm in the head and 2.4mm in the tail cap. So now it’s like a twisty, the tail cap screws down onto the cell and if it weren’t bottoming out on the brass spacer it’d crush the cell. No springs either end, direct contact.

So now it does a whopping 3041.7 lumens on the 4 XP-L W2 1D emitters. Crazy little dynamo it is, lights up a room bouncing it off the ceiling! Big Smile

That is a lot of lumens for a 2× 26650 light. Wow, when you stop and think about it! I still haven’t cracked my pt14 open yet. It’s still in the plans though.

Yeah, seeing that much light coming from a single cell palm sized little pineapple looking light is just mindboggling. Big Smile

Has anyone else swapped emitters, or modified their PT series light recently?

My 18 gets all the use since putting in the 219B sw40s from I.S.
The lumens are not missed, Turbo is still more than needed for most purposes.

Not sure why but that reflectored version really really interests me. Probably copper or brass, as much as I like Ti I wish they’d kept the same design. So the copper one, ready to handle whatever I throw at it, is probably where I’d go if monies were there for it.

I have mine running on a 18500 by using a pair of brass rings, one on each end, to act as ground spacers. This let’s it do some crazy lumens which is just giggly insane from such a small light. Big Smile

Is that an optical illusion or does the Ti PT18 have a larger dia head? Looks pretty sweet, for sure, perhaps such a light would be best left in stock trim and just enjoyed for it’s sheer elegance…

I think its just the camera angle that makes the ti head look larger.

copper is available w 18350 tube…
Caution: clicking the pic, can can lead to pain in the wallet LOL

here is” a brass one”:http://www.ebay.com/itm/Blackwater-SR71-Bs-3x-CREE-XP-G2-1000lm-USB-Rechargeable-LED-Brass-Flashlight-/391525494017?_trksid=p2385738.m2548.l4275 for cheap, but, its conductivity is less than aluminum afaik

Nobody should bring up this thread ever again! I just really love these PT-series lights! They just keep calling to me.

And Dale…

I didn’t say I would put 3 XHP-50.2’s in it, did I? Silly

I do love these little lights though, such magnificent wow factor… just gotta love it!
