Found on reddit : 18350 tube for FW3A
Add a new pocketclip that will work with that and Iām in!
Someone posted their home made version somewhere around here. They found an 18350 tube from another light and then made their own inner tube. Is that what weāre looking at or is this made by Lumintop?
If Lumintop, then itās a big deal. If homemade, then itās ehh. Good for that person, but not those who want to buy it.
Pictures of the FW3A 18350 tube are from Martinās facebook account so it might be official : Redirecting...
Itās a bit odd that it hasnāt been announced here first since the FW3A is a TLF/BLF flashlight. 
I think Lumintop designed this accessory, not a BLF team member ;)
I did not share the pics here because it's not easy using the phone :(
planned to do so tonight from my PC
OK martin, no big deal.
So there is a 18350 tube with a machined cigar grip ring and a 2nd one without ?
Somebody? Did not find a 18350 tubeā¦I bored the tail end and machined the tube to a press fitā¦the Ti/mini is at a Jewelry store to be Laser welded inside the tube as I machined a double lap joint for extra strengthā¦.
. Sent a bunch of pictures of my builds to Neal who in turn sent to Lumintop to get the ball rolling, thank Neal for pounding this into Lumintops head, they didnāt want to do it initiallyā¦
. Neal sent me this badass Titanium clip I guess for helping?ā¦ so I mounted itā¦ added tritsā¦
. Not too bad for being āHomemadeā I guessā¦ 
Very cool! That mokume gane clip looks very excited to be on that light!
Hahaa yep excited, I wanted so badly to put it on the FW3a mini but it is too longā¦ so looking into finding or designing shorter clips for my mini FW3ās I plan on making more of the āHomemadeā Ti/miniās for a few close family/friendsā¦
I want that clip on a Cu version. That needs to be an option.
Direct from lumintop:
Awesome. I think rubber grip ring myself.
18350 version looks nice.
I think it looks strange. Maybe it looks better without the rings. Kawiboys version for the win for now.
Separate so we can use it if we want or not. One more thing, COPPER please!

Also:)
I would say that the rubber, removeable ring would be better for me. Iād buy one for each of my lights.
Removable ring is better I think. By the way, what are the current best 18350 cells?
It would be a good idea if those could be sold with the tubes.
The rubber one looks better.
Best in what way? I use Vapcel 1000mAh (purple) in all my 18350 lights but the largest available capacity is what I base my choice on, there may be a higher current option if you want more output at the cost of runtime.
