You could try contacting Lumintop or one of the vendors that sells the FW3A. Alternately, flashlightlens.com has amazing lenses in a variety of sizes.
Drops right in with zero modification :+1:
I’m not sure what you’re asking here. The fw3a driver is designed specifically to only fit the fw3a type of light. The body of the fw3a is only designed to work with that one driver design. You’re not going to be able to install a different driver inside an fw3a host or be able to use the fw3a driver in a different host. Those parts are specifically designed to work together.
It’s referring to the below quoted post:
Shouldn’t be any issues there.
Yup, I indeed failed to quote the post by Kindle. Sorry for the confusion, and thanks for clearing it up as well as the answers!
Thank you for your answer! Checked flashlightlens.com, seems that they don’t have right size for FW3A, so the lumintop is the only option. I have sapphire glass from AliExpress, but it’s without ar coating.
Neal’s Gadgets has sapphire. Communication is terrible but has been okay if you are persistent and patient.
I bought one of the launch units from Nealsgadgets way back in April 2019. I use the light regularly and am still very happy with it.
I remember writing some initial feedback when I first got it but after all this time I forgot most of them. The color temp I had wanted was not available so I went with the warmer 7A. I see there is now a 219C 4000k which is perfect but it is $$$! I can’t remember what CRI the 7A is but I wish a 90+ was available at launch.
Bummer to hear I could not buy “the same” light any more… should have bought a second one as a backup!
So thanks again for all of your hard work.
Neal stops shipping in Russia a few years ago, and with drop shipping price of the glass will be incredibly high 
so a 14500 variant is releasing soon…
Saw that, hopefully they make it a single emitter not triple.
looks to be triple.
Sorry. Where is this info?
Thanks. Does not look like a good use of the 14500 form factor.
So if someone wants to know - I have contacted Lumintop via AliExpress and they send me this glass for 6$
I bought my FW3A in November 2019 with SST20s and I EDCed it for a while but, believe or not, I put it away. I read something in a post that rekindled my interest and even ran a few tests. I was messing around with it in my 'box', after calibrating it, measured turbo, repeat turbo and max ramp. It looked like this and I'm wondering what causes the pattern circled in red... specifically the half-way point of the peak.
Thank you!
Thermal regulation.
Updated the top post:
Warning to potential buyers (2021)
The FW3A design has been changed many times since launch, with quite a few downgrades. It is not the same light any more. The 2021 model appears to be downgraded so much that it is no longer compatible with the upstream FW3A firmware. It’s missing an entire power channel, as shown in the pic below.
Additionally, the FW1A has been downgraded in at least two major ways — the reflector no longer focuses correctly, and the driver no longer has the primary regulated power channel.
These are only a few of the many downgrades though. Almost every time a new batch was produced, people reported surprising new changes, and most were not for the better. Several vendors have dropped the entire product line because it had too many problems and they had to issue too many refunds.
So, be warned: If you buy a FW3A, FW1A, or any of its other derivatives, you probably won’t get the light described in this thread.
Left: Original FW3A driver. Right: Downgraded version from 2020-12.
