No, it works fine with a longer BlueSword spring…2025lm is enough in this little guy… 
I thought about cutting into the taper…making it shorter but the same diameter as the straight shank of the stock body… then a sharper angle…re-taper to blend it, but then it would be bare aluminum and I would have to blast and polish it and use it on one of my 2 bare aluminum FW3’s… I wanted to see how it looked as a stock color… maybe on the next one…
Obsess much, KB? 
Man that 18350 tube/light looks great! I want one!
Making contact is one thing, shortening the light as much as possible is another. 
IMHO you have the most awesome FW3A on the planet already but maybe it’s possible to improve it still?
Maybe you could alternatively reduce taper depth?
Only with options… got to have a plan “B” maybe even a plan “C”
That would of been plan “B”…If I would of screwed up…….
I got a copper FW3C with working secodaries from JC,plus i have the normal CW version
The aux LED do ramp up/down, when put alongside my CW FW3 there isnt a lot of difference lumen wise but the tint is different due to LED swap
You should ask for the firmware source code and see if he is willing to give it to you.
KB why don’t you do a GB with 18350 tubes?
I sent pic’s to NEAL…
And now we pray for them to listen our wishes :partying_face: :innocent:
Awesome I’ll hold thumbs
I’m not aware of any production clips. I’d be interested if anyone else knows of one.
I designed a clip and had it cut by a local waterjet company - unfortunately, I used the wrong material, it isn’t stiff enough. I’m not extremely happy with the shape either. I might remake one using stainless steel or a higher grade of titanium.
I have been using the clip from my Emisar D4 until I design a new version
That looks great!! I’d be down to buy one from you if you decide to have another go at it. I’ve got a polished titanium FW3 hopefully on the way soon that will be perfect for it.
That is the one real thing missing on the FW3A, a decent deep carry clip. The stock clip, both V1 and V2 seem to be plenty strong. They do get caught on a seat belt from time to time and I have not killed either one.
I only hope to add to this thread, not take away from the custom diffusers.
Both the Felix AOD-S and NiteCore NDF25 diffusers fit very, very snugly on the FW3A. They are very useful with candle mode. Of the two, I prefer the AOD-S, as it can be used either tail standing or diffuser down.
Thanks for the info. I like the look of the AOD-S.
The AOD-S does not look to bad. I am not a fan of rigid diffusers, they do not pocket well. I really hope to find one of the smallish silicone ones that will fit, none of my selection will fit. The ideal one, for me, would be similar to the one that fits the TiTool. I may try to make a form and form one up, not sure how well that will go.
