Good point I'm not as cautious as most on here with some stuff but I've have seen Some people do some really stupid stuff at work. Like running a 18650/16340 together in a 3 cell light😂 when I saw it and asked him about it he said "been doing that for awhile now". Can't fix stupid 😁

When I received it I thoroughly cleaned and lubed it as I do with about anything metal I purchase. It is certainly the QTC pill as I did use a washer for a spacer (on the negative terminal) and it worked fine.
Pretty sure I've narrowed it down to the QTC. It is just flickers unless fully compressed basically. I pulled the pill and started trying to take it apart, seems like a delrin sandwich with a piece of QTC in it. Just unsure if it unthreads or is press fit. Either way, I had trouble getting it apart on the first try. I will mess with it again tonight. I am pretty mechanically inclined and have a lot of tools. I'm also a bit disappointed in it flickering so much.
I have read all (I think) of the threads regarding this but didn't find anything relating to getting the pill apart. I've seen pills apart but it wasn't clear if they went back together.
I had also read how the QTC is smoother with the larger lights so it's a little annoyance. Worst case it will end up a single mode and I'll ask for a new pill eventually.
If I get it apart I will update the thread.

Do these 17500s come with different battery tubes, or do you need to order each of them separately?
Many thanks!

It's just a spacer set that works in the battery tube you already have. You get them all in one set. It's really worth it as you can literally run A ton of cells in her.

The CR123A Logan tube is compatible too.

Is this a separate tube you buy? Compatible with what cells? Their website leaves a bit to be desired, or it's just me.

Yes, available separately or as a complete light.
The Logan CR123A tube is compatible with 16340 cells. And probably CR123A, I imagine

The 17500 head on a cr123 tube makes a very small pocket powerhouse.But I like the 17500 body better. It's easier To use and the availability to run sooo many different cells really makes it A true SHTF light. I love mine.

Messed with mine quite a bit tonight. The pill isn't coming apart. It looks like it may be snapped together but I can't get it to pop apart if that is the case.
I turned the wrench side contact enough that if it was threaded it would have come apart. The opposite side didn't even want to spin so I doubt that it is threaded. It may just be pressed together. I did clean the entire thing very well again. It didn't help but running the pill between the CR123 spacer ( on the negative end) and a CR123s on the positive end made a very slight improvement.
Gonna just stash this away into some kit for an emergency. I'll include a washer as a negative contact. I was hoping to get a little more use out of it, but I have enough alternatives that it isn't worth any more headache. It seems well suited to being available for an emergency as it does provide light with a number of cells.
I will also email Robyn as we have been in contact a bit and get her take on it. I will say that she has provided excellent customer service to me recently, and has been responsive to emails within a couple days.
Still love the Peaks.

I have another question about my Logan.
I would like to be able to use the twisty function with a AA battery but it seems I need to twist the head very tightly to get it to work properly. I was thinking of using a thin spacer (washer) and did not fully understand the above discussion about it not being advisable to do so.
Is there a safe way to make the battery a little "longer"?
I have also noticed a few times that it turned itself on. I assume this is from the QTC material expanding a bit.

Mine also is a little short with 14500/ AA batteries requiring it to be pretty snugged up to work.
Washers work but they rattle when not snugged down so I wouldn't store it that way. My QTC pill fits snugly enough to hold back some resistance from whatever is under it. Foil probably would work well as long as you can poke it out later.
I haven't messed with mine much more since initial experimentation but I opened the drawer it was in and it too was slightly on even though I had unscrewed the head what I thought was a generous amount.

Ya mine will do that even when I turn it off. I usually give it an extra turn or tap it against my palm to make sure it's off. I'm not to worried if it turns on by itself on very low. Battery drain is not much on these things. Been using mine for well over a month with the same 17500.It really is A perfect Light if your heading out or on vacation and not sure what batteries you can get your hands on.

I've been carrying around my Logan17500 for almost a month now, and I've gotta say fellas, I'm impressed.
First I was a bit hesitant to buy one of these as there is not much buzz around them, and the only thing that most people mentioning the company agreed upon was that they are pretty hard to reach by any means.
Well, firstly I got a response to the mail the same day by Robyn, and as I had special requests we had exchanged quite a few mails, and the response was always quick, so that was a sigh of relief there.
The second thing that a lot of people complained about was the website, and I don't know how it looked like back then, but now it's quite simple and easy to manage.
After mucking about with it constantly I figured out the "tactical only" configuration, which is actually an accidental result of the build.
So if you have the keychain body with the momentary switch, you can just put the battery first into the tube, then the spacer ( if any ), then the qtc on top, tighten it down to the desired output you'd want, and voila, you have a momentary only light. You can pre-set the output with the tightness of the head and activate by just lightly pushing in the tail button. It's brilliant!
( you lose contant-on tho, but that isn't an issue for me )
The other thing I was unsure of, is that just how sturdy it is, but one night I dropped it on the pavement by accident, and after a few bounces and roll I managed to pick it up. Much to my surprise right then I couldn't feel the dent/scratch as to which part of the body it landed on, and the optics seemed to be intact so I was using it on the way home as well. When I arrived home I inspected the light, and much to my amusement there was only the slightest little ( about 0.5 mm ) scratch on the head only a few microns deep. As someone who uses HA alu. lights most of the time I was just amazed how little f.ks were given by this light to bouncing around on concrete.
I've played around with different power sources as well, and even though the 17500 li-ion gives a bit more oomph in the beginning, the circuit protection cuts off the cell waaaaay before I'd be comfortable with it, so I just settled with the good old CR123, and it's been going strong. Luckily it's a vampiric driver, so you can basically use any primary until it's sucked dry.
So all in all, customer service was top notch, the light is amazing in both durability and color rendering, and it has become part of my EDC rotation.

That's what's in my pocket most of the time.
I put the Oveready clip on mine.

Got them in SS. You can drop them all day and you aren't going to hurt them. The biggest + is the availability to run so many different cells. Your right it really doesn't get the credit it deserves. I love them.

I have a brass 17500 with neutral xpg. Love it. Always have been a peak fan. They definitely deserve more press than they get. I recently got a Eiger AAA keychain with 4500K 219b rides on my keys. So if I'm out of my house I've got a Peak on me. 😎

Playing around with my new CRI measuring tool I figured I'd check my Logan, as it was a special order with the famous "Nichia NVSL219BT-V1 4000K D200 L2 R9080"
I knew it was impressive without any data, the colors look great, but damn the actual results are just mad..
The particular LED that I got is actuall not only R9080 but almost perfect... ( yes I do know there is a small margin of error, but even if you take a few percent off it's still mighty amazing )
way to go Peak!

Very nice data! I have two Eigers with the same LED and they are some of my favorites.
