Shouldnāt that be Double-click from ON no longer turns off before going to the ceiling level?

Double click from ON always goes to turbo, not ceiling. Double click from OFF goes to ceiling max first. Previously when you double clicked from OFF, the light turned on and off quickly before going to ceiling. This is the case with my review light with old firmware as well.
The FW3A on turbo with a 30Q heats up to about 50Ā°C when the thermal limit is set to 55Ā°C. It stabilizes at around 46-48Ā°C. This is a good setting for not burning your hand. Also loving how quickly the heat transfers to the battery tube from the head.
In case we do end up with the slightly older version of the firmware (not that it sounds like a big deal), the FW3A has accupuncture style flashing holes, right? At least, I think thatās what I heard but I donāt have time to check at the moment. Iāll search some posts later when I get time, assuming nobody has already answered by then. Reflashing should be somewhat easy if this is the case though.
Great review!
Thank you so much for your work.
One little thing
Do you mean non-magnetic ?
Edit: I should read first the whole thread, itās already mentioned
Kiitos suuresta tyƶstƤ, maukka!
The Emisar D4S is flashable like that.
Thanks for your review maukka, looking forward to your beamshots/test data with the correct optic (10511) installed.
Happy to report that the beam is very pretty with the 10511 optics. No discoloration in the middle of the beam. Just some radial artifacts at the edge of the beam, which are not even visible on a white wall unless you rotate the light.
Sounds about right. It uses a window of 10 C as its target zone. If it can get the temperature anywhere in that window, it stops trying to adjust the output. So with a limit of 55 C, the window would be from 45 C to 55 C.
If you happen to have some other optics like 10507 or 10509 it would be nice to have some pictures, all from the same distance, to see what they look like. Assuming your not too busy.
Thatās more like what I was expecting, thanks for checking and getting your findings up so quickly :+1:
A quick note about lumen numbers:
Maukka uses proper ANSI lumens, but a lot of the flashlight industry uses a different scale which has more impressive-looking numbers. I call this second one the ācpfselfbuilt scaleā because he was the one who really perfected it. He did this by measuring a lot of lights, trusting that the manufacturerās values were correct, and fitting a curve to the average. So it does a pretty good job representing a lot of brands which were popular at the time, even if itās not really accurate. Anyway, the difference between the two is roughly 30% or 40%, so 100 ANSI lumens would be about 130 or 140 cpfselfbuilt lumens.
My measurements, so far, have used a super low-tech āintegrating milk cartonā which I calibrated to match cpfselfbuiltās numbers as closely as possible. One of these days Iāll buy some reference lights from maukka so I can get more accurate numbers, and perhaps build a proper integrating sphereā¦ but that hasnāt happened yet.
When I measured my FW3A production sample, I got the following results:
ā¦ and maukkaās numbers for these same levels are:
So in this case, the difference is 31%. That is, assuming the two lights actually produce the same amount of light, which is questionable because the emitters are different tints with unknown bins.
Maukka also measured 2800 lm at 0s on turbo. Using the same 31% correction factor, this works out to about 3666 lm on the scale Iāve been using. That number is probably more directly comparable to the ~4300 lm I got with an Emisar D4.
All the FET / turbo stuff is going to be incredibly approximate though, not precise at all. The actual values are highly dependent on analog factors like the battery condition, the cleanliness of the contacts, etc. But mostly I wanted to let people know that 2800 ANSI lumens is not a disappointing result. Itāll probably look almost as bright as a D4. Unless theyāre side-by-side, it would be hard to tell the difference.
Re: Flashing vias - Ah okay, I must have been thinking of a different flashlight then. I know the D4S has them, and I think there was a rather premium keychain light project that was going to have them too. That might have been what I was thinking of.
The fifty shades of grey anodizing is looking really nice. Itās silvery reflections can fool you depending on the lighting condition. Looking at the short angled area of the body near the clipā¦ In one pic itās the brightest area of the body, but in another pic this area of is turned away from the camera, and itās so dark that at first glance I thought āWhy is there an extra O-ring there?ā Itās even better because something that could have been a major drawback of the light turns out to be a superior point.
Itās not as good as the naked prototype, but itās as good as it possibly could be.
For comparison, hereās some lights so you can get an idea of the shade of grey of the FW3A
Beamshot comparison with different optics. The difference between 10508 and 10509 in the photos is very small, but measurably significant. It is possible though, that the optic installed in the light was 10509, since I donāt have a 10508 to compare it to.

Nice. Thanks
Very nice review for a very nice flashlight!
Question regarding updating the firmware, since there are no flashing vias, how does one update the firmware if thatās possible?
