FW3A Troubleshooting / FAQ

I bought mine individually at the local hardware store for 25 or 30 cents each.

Shoot me a PM with your address and I’ll mail a few to you.

I just received a new FW1A (new version with the retaining ring in the tailcap) and it does not turn on. When I screw the head on I get a single flash, but then nothing. I’ve checked that the driver retaining ring is tight, took the head off, tightened the tailcap as much as I can, and then reassembled but still nothing. I checked continuity between the tailcap spring and outer trace on the switch PCB that’s supposed to contact the inner tube and I get good continuity when I press the switch.

Any ideas?

Edit: I replaced the standard bezel with the SS one and now when I tighten the head down, the light comes on by itself and steps up to a bright setting and does not respond to button presses…

Edit 2: I completely disassembled the tailcap and reassembled and the light seems to be working correctly now. The switch retaining ring was not tight at all and the leading edge of one of the notches was totally gouged. The assembler who installed the ring obviously botched the operation. We’ll see how it works from now on.

I posted the same on the other thread, buying 100 when I just need 1 is too much to handle for my overflowing “stuff” drawers.

I have a gray Nichia and Green SST-20.

Both needed fiddling with. Cleaning, adjusting, pitching spurious components, etc. Gray seems stable now. Green seems to have mind of its own at times. Won’t turn on. Stays on, etc. - even when adjusted, tested and just left to sit for a few days.

Not enough mfr tolerance design into it by engineers. They are lovable but not QC’d well enough.

If you’re in the US I can send you O rings for $1 to cover envelope and postage. Send PM

How do I get turbo off of the top of the ramp? I accidentaly turned that configuration on. Thanks

With light turned On, click 4 times fast to enter ramp config mode. At the prompts (fluttering light), respectively, click 1 time, then 21 times. If there is a 3rd prompt, click 7 times (this is seen when in stepped ramping mode).

I think I did it with light on, 4 clicks then maybe 1 after flutter, is that what turns turbo to ramp top? I didnt do 20ish clicks to enable it, seems odd to disenable with 21 clicks lol. Lesson is don’t play with this light while half asleep.

The first flutter is were you set the ramp floor. 1 click sets the lowest level.

The second flutter sets the ramp upper level. 21 clicks means 20 levels below max. Max level (Turbo) is 150. Level 130 is max regulated (stock).

I’m still confused, I somehow added turbo to the ramp max with just one or 2 clicks after one of the flutters. I would just like to put it back to the factory default, thats what I was used to using, that is the top of the ramp was high (I think lol) and then still need double click for turbo. Thanks for help Jason, if you could confirm your previous instructions are what I need to do before I fudge it up anymore.

Assuming you are in smooth ramping mode, you can set the ramp floor minimum and maximum.

With light turned On, click 4 times fast. At the prompts (fluttering light) click 1 time it will respond and then then flutter a second time. This second flutter is where it sets the ramp max. Default is 21 clicks. If you click 1 time ramp max will be Turbo, so don’t do that, click 21 times.

Thanks a lot Jason, that worked, appreciate the help, the manual is kinda confusing.

Anduril is a little too easy to get into the menu settings, Imho.

You can also set the ramp min and max in stepped ramping. It has seperate settings. Same procedure except you make sure your in stepped ramping mode. It has a 3rd flutter which is the number of steps you want. Default is 7.

This also allows for two different momentary moon modes when the light is locked out. Hold gives you the floor for the current ramp and click, hold gives you the floor for the other ramp. Pretty cool, and one of the more obscure features.

Try soft candle wax, like from scented candles for example.
It doesn’t cause grey gunk grease and really helps smoothening the threads.

One of mine no longer stops at the top of the ramp before turbo, meaning it no longer takes a double click to reach turbo. Did I accidentally re-configure it that way, or is it a quirk?

That is the default behavior. Top of the ramp is the highest brightness for LT1.

This is for the FW3A. All three originally required a double click to turbo, and now one of them doesn’t. It just ramps to turbo without a double click.

You may have accidentally clicked 4 times while on and reset the ramp levels. Look a few posts above to reset it.
