Oh I misread, I thought he was trying to get to the switch.

I wonder if anyone can confirm that the 18350 tube works with the first gen body.

18350 tube does work with the first batch FW3A without any issues.

Could you take a photo of the body and the inner tube? I just bought mine and I can’t seem to make mine work. Not 100% sure if mine is a first batch FW3A but mine doesn’t have the retaining ring on the tailcap. Looking at the 18650 and 18350 inner tubes, the 18350 protrudes more.

Tried to use the inner tube both ways and I can’t fully screw down the tail or the head where the thicker rim(bottom part on the 18350 tube in the image) is positioned at. I don’t know if it’s an incompatible inner tube or I’m doing something wrong.

Any advice?

The inner tube should only work one direction, with the lip near the tail.

Is your oring under the lip on the smaller tube?

Tighten the tail cap first, then the head.

You can also tighten just the tail and then check to make sure the switch is working.

Yes, my oring is under the lip on the smaller tube. I also tightened the tail cap first and it didn’t seem to do anything. Tightening it down just brings it to this.

Sorry I’m not sure what you mean by

Could you elaborate?

I tried to remove the oring from the lip under the inner tube and I can tighten it down further, I get a blink so i guess there is power but clicking the switch still does nothing.

Oh okay, so there is no beep to confirm the continuity when I click the switch. I tried to tighten it down more but I think it’s tightened well enough. Any suggestions to fix this?..

Not really, maybe try with and without the oring. Maybe someone has an better idea.

I just wanted to post some comparison photos that I took with the different tubes and clips and also side by side with the FW1A!
I really love these lights, did I mentioned it already? Wink

Enjoy! BTW, all of these (except the Sony battery) was bought from www.nealsgadgets.com Wink
Stuff I bought recently!

FW1A >>>>> FW3A
18350 tube

18500 tube

Tailcaps & Heads (FW1A has a retaining ring on the tail and the retaning ring on the driver is brass)

Tubes (FW3A > FW1A) [ yeah, they are different, but interchangeable, as far as I could test them and put them to work! Also, the clip on the FW1A is not dark, but it can be easily darkened with a blow torch, unlike the deep carry clip, that will probably take more efforts to do that! ]

FW1A 18350 & FW3A 18500 >>>> FW3A 18350 & FW1A 18500

Can you check if your retaining ring in the tailcap is centered and that the inner command tube fits inside of it? You can also try to put the command tube in first and then screw on the outer tube.

A rare possibility is a defective switch.

I had multiple FW3 lights with contact problems that were fixed by tightening the tube and tailcap.

However, that fix did NOT work on my Ti-Cu FW3T. Further checking revealed that the microswitch was actually defective.

  • It worked, but only if I pressed REALLY hard and even then only some of the time.
  • When I swapped the switch board for one from a different FW3 light the switch worked normally without excess pressure being needed.
  • I then swapped the defective board into a different FW3 light and it was still broken even though in a completely different light.

For this defective switch FW3 light I conclude that I need to desolder and remove the switch from the board and replace it with a different switch.

Your forgetting that his tail switch already works fine, as seen with the longer tube. It’s just the shorter tube that there is a contact problem.

You might try tightening harder.

You can check continuity with the battery tube removed, just slide the inner tube against the switch. That should definitely work.

Are both ends of the new tube clean and bare metal? No coatings or residue covering the contact area?

At my switch was dirt under the switch. I also had to push hard. The plate can be dismantled.

I don’t have a retaining ring on mine. I had the one without it. It’s aligned really well as far as I can tell.

The tail cap and head works fine on the 18650 tube so I’m sure the short tube is the issue

I tried to check continuity without the battery tube. There really is no beep. I think the inner tube really is just defective. Tapping at both ends of the inner tube doesn’t seem to beep either.

I wiped everything with IPA and yes they’re all bare metal.

wow

the black, inner tube has no continuity? 

 

can you try to sand both ends a little bit? 

(I would use a 400 grid and press with the thumb against the tube end, then go around twice) 

it only needs contact on one point each ends Wink

I did that too but with a sharpening stone. Not sure what grit but I made sure to see some scratches on it to make sure a new surface has formed.

Here they are. You can see when screwed together the head and tail are not bottomed out on the battery tube, which is good.

Ok. I got frustrated and mad which was a good thing I guess and put it on a vice. It works for now but I still get some clicks that do nothing. Better than nothing I guess. Thanks for all the help! Hopefully I didn’t make it permanently an 18350.

Edit: It doesn’t work again :FACEPALM:. After fixing it I laid it on my table. Wanted to play around with it so I picked it up and it doesn’t work anymore.

Unfortunately I can’t take pictures until end of the next week. I actually remember having to tighten the whole light quite a lot to ensure it register every click.
Ill try to measure my 18350 inner tube as well.

Checked the switch on my defective FW3T. This is the one with the unreliable switch.

The switch is super-simple. Literally just a piece of spring steel on top of a PCB. The steel is held on with kapton tape. I removed the tape and cleaned underneath with deoxit. Then replaced the tape with fresh tape.

Now the switch works, but the light still does not when I use the black inner tube that came with it. For some reason the tube just isn’t long enough. Tubes from other FW3 lights work just fine, but the one that came with it is just too short to make contact.

To fix, I think I’d need to pull out the driver and/or tailcap and add a bit of extra solder along the contact ring for the inner tube.

I wonder where the difference in tubes lies.. If you stood the working one next to then non-working one….

IMO, the FW3A is a nice light (though I don’t use mine), but the manufacturing tolerances are too tight for inexpensive production. I know it was designed to be something unique, but a more simple design, perhaps with a side switch or a mechanical tail switch, would have resulted in less issues.

The FW3A is kind of like a cheap HDS light. I know the HDS is way over-priced, but perhaps the FW3A is a bit under-priced.

Well, they did make a side switch version. It’s not as unique, though

I had one of my FW3A powder coated. sort of…
I guess the first one went bad, after a couple tries… the guy replaced the light and powder coated the body and tail cap….
He assembled it and sent it back.looks kinda cool.but it Doesnt work
I am still trying to figure out where it all goes south…The light engine may be faulty.I can , by swapping things around, and omitting the clip, get the light to work in a basic fashion.
it turns on, ramps about half way…will not go turbo with a double click. Will not show battery with triple click…
it’s all wonky. a failed experiment I am afraid.

The inner black tube, I have two now, and they are markedly different….no idea if the paint is screwing up continuity or what
I cant screw the brass retaining ring into the painted tailcap, overspray?
It lights with both tail caps, with no clip.. but no turbo or other multi button commands… odd

I will probably box it up and give it to Dale or something

Sounds like your in muggle mode or basic mode. Try 6 fast clicks from off.

Didn’t really think of that…
If that’s it, it’d be nice to get it running with the clip on…

The clip just needs room. As long as it doesn’t prevent the tail cap from fully screwing down (with head loose, then tighten head fully), it should not make a difference in functionality. Sometimes you have to tighten pretty hard.
