Mec-Army PT-16, Triple XP-G2 in a "Nutshell" (NOW a 3402 Lumen Quad!)

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? :smiley:

Next couple of weeks….

Dang thing is gonna cost me another $100 to buy the XP-L’s… Ugh!

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! :smiley:

That is a lot of lumens for a 2x 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. :smiley:

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.

which one would you like?:slight_smile:

there was a copper PT-16 too!

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. :smiley:

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…

C’mon… expect us to believe that? :smiley:

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

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

And the “equivalent” sr-series doesn’t match up. In my opinion anyway.

there are a couple of differences that might matter to some

advantage SR71
Prices are similar for the anodized version, prices are lower for the Brass and Ti SR71 than the PT16.
The SR71 spec says 5 lumen low, PT16 says 10 lumen (I don’t know if the specs are accurate)
the anodized SR71 seems to use a reflector with glass lens, PT16 has the plastic TIR
the SR71 has a smooth head and tail so easier on pocket wear, PT16 head has cuts in the head to create fins, and the triad tail is more likely to gouge a pocket.

advantage PT16
No copper option for SR71, yes copper option for PT16
SR71 has memory and does not start on low, the v2 and v3 PT16 starts on low, no memory.

equal
both SR71 and PT16 v3, are 18350 compatible

The triad tail, pineapple knurling, and finned head are all what makes the design work for me. The SR71 loses out in the design department… if I were buying a copper or brass version it would be in the PT16 style, surely not the SR71.

I agree. Also the pt16 has fins and has some edges but all the edges are very smooth. I can’t imagine it eating away at a pocket. It just slips in. In fact it might be too smooth and slippery for some. It lacks grip but somehow that is what makes it feel “rich” in my eye at least.

The SR71 is a non starter with me because it has V1 UI

I just received a PT-18 modded to N219b, more info here
I think its freaking awesome! The pics made it look much bigger than it seems in real life. The head is so cute!
Love at first sight.

Indeed. Tiny. Well made and just so much fun to use.

Especially at over 3000 lumens! :smiley:

:wink: that sounds Hot!

On Turbo with the stock NoPWM driver, the 92 CRI N219b are making 450 lumens :slight_smile:

I have shown off the ginormous (relative) output of this very small light by shining it at my hand, so as to give the person in front of me an idea of the total output. It’s blinding! And the heat out the front is intense from the 4 emitters. I even tried holding my hand up at eye level, from a few feet away, and with eyes closed turning the light on in Turbo… the intensity is blinding even through your eyelids! Fortunately it has 64 levels of ramping so all this heat and current consumption can be controlled quite easily. It also has last mode memory, so you don’t lose the setting you were last working with by turning it off. Click on and hold for instant moon, click on then click again for instant turbo. Seems odd to think of a 3000+ lumen light having a moon mode, but it is actually quite low.

It’s not high CRI though. And while I might could help that a lot with a color filter, the filter would undoubtedly melt if running much Turbo. I have other lights for high CRI use though, my favorite being a 95 CRI Cree COB at 2004 lumens in mule configuration to avoid artifacts or hot spots, very helpful in macro photography.
