Thanks KawiBoy1428, JasonWW and hank. That FAQ looks like what I was looking for.. will be poring through that for a lot of information. I really like this light when it’s working, which seems to be about 80% of the time! Smile

Yes it has the pocket clip installed — I guess to remove it I have to remove the tail cap? Not completely unwilling to do that but I understand reassembly may take some doing and there’s a small part that can get lost if I’m not careful? (I will be if I do it). I like the clip but would be willing to remove it if that’s a fix.

For some people the clip is a bit too thick and it prevents the tail cap from tightening all the way down. If nothing else works and there is no gap around the clip, then try removing the clip and see if that fixes it. If so, you can make the clip thinner and reinstall it.

One of the tips from the FAQ / Troubleshooting thread (link a few comments up) seems to have fixed it for me.

It was the sequence of loosen tail and head, then tighten tail first, then tighten head. After that, it’s working great!

The sequence makes sense also (as you well know, but writing for the benefit of others here) since that inside tube that needs to make contact can be positioned in the wrong place, and only by having the head loose will there be room for the act of tightening the tail to push it up enough to sit where it can make good contact.

I imagine Lumintop could prevent this by making sure their final assembly entails tightening the tail first. But it’s a subtle point.

Edit: so to be clear, I got it working without having to remove the clip.

That’s the first thing I mentioned. Lol

Lumintop wanted to glue the tail caps. That would have solved that issue, but then you can’t change the clip or mod the button without a lot of work. So it’s got some compromises. Which is the better choice? IDK.

Welp I did read what you posted, and thank you :-).

To be fair, what you said exactly was:

>Make sure to loosen head, tighten tail firmly, then tighten head firmly.

My tail was already, prior to reading this, tightened firmly. I tried to tighten it some more, and it didn’t budge. I can assure you it was very tight.

So as a newbie to this flashlight it wasn’t clear to me that I needed to do anything more with the tail. And I effectively did as instructed by attempting to tighten it. And it did not fix the problem.

Only after I added the additional step of loosening the tail before tightening (this step is clearly spelled out in the troubleshooting thread), did it work.

What would have helped me right off the bat would have been:

“Make sure to loosen head, loosen tail, tighten tail firmly, then tighten head firmly, in that order.”

Just saying this in the spirit of feedback! Please don’t get me wrong; I very much appreciate all your help, thank you!

I just put the light in Muggle mode, and it works fine, except you apparently cannot set the ramping mode to anything else other than 5-240 lumens. I was under the impression I could maybe lift the ceiling lumens up a bit, but just read the instructions. It says to click on the switch four times while on to get into the ramp config mode, then hit the switch one time to set the lower level, or two times to set the upper one. So I clicked four times, then two, then 32 times and nothing happened. The other thing I noticed was that even when the light was at the upper level of 240 lumens, it started to slowly dim after it was on about a minute. The light was not even warm. I found another post about this issue and apparently it is a known one, but there is no solution. Am I correct?

Muggle mode doesnt allow anything but ramping up and down. You have no menu options except to leave the mode.

There is a bug in that mode that activates the thermal stepdown too early. I haven’t looked into it. I think if it ramps down you can just ramp it back up. There is no fix that I’m aware of.

My light was starting to not only auto ramp down, but would all of a sudden just get brighter. The problem is very erratic and random. I just removed the head, tail, and the metal tube inside the light and cleaned it thoroughly with electronic contact cleaner. I noticed before I cleaned everything that the inner tube area by the tail cap, where it has an o-ring, was sticking up a bit too far where you could see the o-ring. After the cleaning, it tucked itself under the bottom of the flashlight body like it should have. So far the light has not auto changed brightness one way or the other. I have not been using it too much since the cleaning, so right now this is pretty inconclusive, but I will report back later.

Strange, on my unit there’s no need to first loosen then retighten the tail. I wonder if your inner tube o-ring was maybe not set right and loosening the tail made it fall into place? Oh well, glad it’s working now.

It’s pretty common to need to loosen the tail before tightening it. The parts float around a bit, and sometimes it takes a few tries to get everything in the right spot.

Does anybody have a photo of where the o-rings on the inner tube are located, or just tell me? I had one break, and there is a second one near the end of it by the tailcap, but where is the other one installed? Thanks!

Just under the lip on the black metal tube. Install it and the o-ring should drop down into the main battery tube where you can’t see it.

There’s only one small white/clear o-ring (inside the light), btw. EDIT: there is a second skinny o-ring on the outside that keeps the clip from rotating.

Thanks! That is where mine is. Somebody else,I think in another thread about this light, said there was two on the tube. The o-ring on mine that broke was a clear one, and that is the one that is on my tube. Maybe it was on the tail cap threads.

Yeah, I think they changed from white to clear. Mine did have another skinny o-ring on top of the clip to keep it from rotating. I took mine off and forgot. So there are two, but only one inside the light.

I have a feeling the odd problems I am getting (auto ramp down, and sudden brightness increasing) have something to do with this tube. I still have over three weeks to decide if I am going to keep this light. So far it is a bit quirky. In the long run, I am not so sure it will be a reliable light.
