FW3A Troubleshooting / FAQ

Good point. Also, greasing the threads generously will help stop water seepage.

I wouldn’t purposely submerge any light that isn’t actually a dive light

Oh my gosh, just caught up on Dbsar’s report of the tailcap spring problems.

I hope whoever is managing production of the tailcaps is reading this. I doubt, but I hope.

I would definitely not submerge it, but I would think light rain or splashing should be fine.

Strange. Do you mean “thicker”? Or was the nubbin of a larger diameter? Mine was fine, just making for a very sensitive switch. I removed the nubbin, installed a 5/32” o-ring and switch has a nice firmness now.

Cross-reference to the other Lumintop QA thread:

I generally don’t have an issue with the firmness of the FWxx switch (I always use lockout), but this light in particular had a defect. The diameter of the nubbin was fine, it was just too long. It was physically longer than the nubbins in my other FWxx lights and was pre-loading the switch when the tailcap was tightened down.

I didn’t replace the nubbin with an whole o-ring, I cut a short piece out of the cross-section of a sufficiently thick o-ring to produce a new nubbin which fits in the original location. It’s a tiny bit larger diameter than the original but the rubber stretches to accommodate.

It definitely has made the switch more stable when pressing off-axis and has improved the tactility, even over my other FWs with properly fitted nubbins from the factory. It’s not immediately apparent to me why this would be. Perhaps a combination of the more pliant material and the slightly larger diameter?

I was always using lockout because of the switch sensitivity. But now I don’t bother with the 5/32” o-ring. I lock out the light when I put it away. Yep, I got that you cut the o-ring, but didn’t quite get that “long” meant “thick”. This o-ring segment technique is interesting. You can cut a variety of thicknesses to see what works best.

My FW3T always starts super dim, moonlight-ish, at first turn on

Even if I ramp it doesn’t remember the ramped value for next turn on, single click

My FW3A is not like this, it remembers the last ramped value.

Everything else works fine.

What am I doing wrong?

Thank you

Does it start there every time? Is it in manual memory mode?

i didn;t think it had a manual memory [no memory] option…

?

one comment - it will do this [start on low], if you happen to hold the button down ‘too long’
it is a feature, to be sure you have a way to start on low
but you have to hold the button down maybe half a second
maybe your button is ‘sticky’ so that it thinks you are doing a slow press for start-on-low?

wle

Yes, every time.

Not clear on manual memory mode, I don’t see it on the instructions.

The FW3T button does seem not a ‘clicky’ as my Fw3a, which does not have this ‘issue’

Manual memory mode on Anduril software is 5 clicks from ON (“5C”). Automatic memory is 5 clicks, but HOLD the last click, from ON (“5H”). See flow chart.

Edit — Oops. Looks like the Anduril version in the FW3As may not have selectable memory mode. Sorry ’bout that.

Was this added on newer versions? My older model does not have this feature.

BTW, I have no clue why it won’t remember it’s level.

My bad. You are correct. Edited above response.

It was manual memory

I did the 5H and boom, now it remembers.

Thanks all.

Oh, so you didn’t reflash it to a newer version, it came with the newer version?

I’ve found some lights have manual memory. Some don’t. Hard to predict what you will get.

Correct, I did not reflash, my FW3T came with the firmware with the memory options, from Illumn.

So now I have two lights with different firmware and it’s bugging me :slight_smile:

I should have read more and bought both from Illumn instead of rushing into the FW3A purchase from another vendor

I have 9 lights with 3 different firmware…. :person_facepalming:

I bought 5 brand new drivers from Lumintop, I used 3 so far… 1 of them has the memory option… so far… the other 2 new drivers are waiting to be used… :smiley: WTF?
