Try something much stronger: citric acid/vinegar + salt.
Remove it from the solution, and let it air dry.
If this doesn’t oxidize it, then it is coated.
Haven’t seen it mentioned here yet… Neal posted on TLF saying 21700 version is also in the works!
Ill try some more, Just acetone’d it….
If someone could respond….couldn’t find answer.
Curious…is the “candle” strobe/flicker (and lightning) mode adjustable in brightness? Or is it preset like most blinkies?
You can hold to increase and tap hold to decrease brightness just like in the normal mode.
That is TOOOOO Awesome! Thanks for the reply!
Brightness in candle mode can be set by tap and hold. Strobe modes have only adjustable speed. Lightning mode has no adjustments (brightness varies on its own).
There’s a sale going on at my local store so i ordered one FW3A.
My light has a brass driver retaining ring, black pocket clip, Lumintop one piece optic and the most important detail is the tail
cap has been glued tight.
The light work flawlessly though, I just wish that i got the one using Carlo optic.
Put it overnight in a bag with smashed hard boiled eggs.
Patinas like crazy.
That sounds odd. They now have the retaining ring for the tail so glue is not necessary. The black clip is definitely an early part. I thought they had fully switched to silver clips before they started using the one piece optic.
Do you see the traces of glue or is it still together and too tight to remove? I have not heard of them gluing any tails. Quite odd.
Maybe the store added the glue to reduce warranty issues?
There is trace of glue on the pocket clip and the inner tube is pretty much stuck inside the body as well so i think there’s a good chance that it has been glued. I’ve also checked with the store, they said all their FW3A have been glued like this from the factory but only in their recent batch and not on the earlier ones.
Received my purple edition today (thanks ToyKeeper). Worked great out of box - I opened it anyway, it has a black retaining ring in the tail, silver clip, and a brass retaining ring in the head. I forget how to check the Anduril version (well, I forget how to check for the manual memory or two-step lockout mode). Also has a glass lens and Carclo optic.
I went with the SST-20 4000K for this one, and I’m not noticing any green, so it’s a pretty good tint. The button doesn’t feel better or worse than I recall the button being on my original, group-buy edition FW3A.
Fake edit: Checked, and it does have a two-step lockout mode. I don’t remember other details to check for, or what Anduril version that indicates.
I might bite the bullet and get liver of sulfur. The baking soda did zip
I got mine 3 days ago, but the batteries I ordered were supposed to arrive yesterday, instead I got this bogus tracking notice “we are unable to access you residence, we will make an attempt on the next business day” which is mailman speak for I am too tired/lazy and want to go home 
. And of course there is no mail tomorrow for holiday, so I have to sit and stare at this light for 2 more days
I got a Amazon.CO.UK deal
for the Lumintop FW3A
10 £ OFF - ask me for the code ;)
Wow that’s a good price! I’d be in if they had the raw 4000K SST20 on there.
some rogue mailman dropped off my batteries on a holiday today! I had similar issues with this V2 version as a lot reported, mostly it wouldn’t shut off, one time right after I hit turbo, man was that hot unscrewing the head. then it wouldn’t turn on after I let it cool. Took it apart and cleaned everything with alcohol, still nothing.
Seems to be working now after I cranked down the tail and head simultaneously, that seems to be best way to get some good leverage. Hopefully that was the only issue.
Now that all the versions are available has anyone tested thermal regulation on the various metal combinations?
Something like a fan cooled 5 minute run time chart for each (assuming the same LED)
I did 30 seconds on the copper and it was too hot to hold.
I posted it on here someplace.
I think it was around 60 C
Every light will be too hot to hold depending on your settings. Not really what I want to know. More interested in something like this:
With temp ceiling set to ~55C and a small fan on. Start from Turbo or Ceiling Max and then record % output for 5 minutes.
Curious how much you are really sacrificing by choosing full Ti for example.
