TLF/BLF/Lumintop FW3A review (18650, 3x XP-L HI cool white)

Thanks for the review maukka. :beer:

Thanks :+1:

That does not sound very production-ish :zipper_mouth_face:

Differences in off-the-shelf parts, as long as the expected parts will be implemented in actual production, don’t concern me too much.

If this is a production test of the custom parts: machining and final driver, tail PCB, MCPCB, etc, that still seems significant enough to reasonably call a production test.

The firmware difference is a bit of a puzzle though. I hope they didn’t have 1800+ drivers built and flashed with an older version of the firmware.

There isn’t much difference between the version it came with and the latest version. The only user-visible differences are:

  • Double-click from off no longer turns off before going to the ceiling level.
  • I added a potential workaround for moon flicker issues, but those have only been reported on Fireflies lights, not on any other brands, so it probably doesn’t matter for the FW3A.

Thanks, there was no artifacts. I’ll have to go through my stash of optics to compare.

great review

thanks Maukka!

Here’s the effect of different Carclo optics to throw. My sample had the 10508 installed by default, but the production light should have the 10511. This was measured at the 1x7135 level and scaled to maximum output for repeatability.

Also, added stepped ramp default (78 lm) runtime https://i.imgur.com/uTsDSDI.png and measured maximum output with 50% drained 30Q (1980 lm @ 0 sec, 850 lm at 30 sec)

edit: fixed the table, it had wrong values

/\ … Very good info. :+1: . Much appreciated. :beer:

edit2: filled the CRI table with rest of the modes https://i.imgur.com/B3mgGg3.png

No real change in tint or CRI within the 7135 modes. Will add CIE tint graph soon, added https://i.imgur.com/el07LR1.png

Measured standby current at a negligible 28 µA

Shouldn’t 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 50°C when the thermal limit is set to 55°C. It stabilizes at around 46-48°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 that’s what I heard but I don’t have time to check at the moment. I’ll 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.

No flashing vias on the driver backside from what I can see.

Great review! :slight_smile:
Thank you so much for your work.

One little thing

Do you mean non-magnetic ?

Edit: I should read first the whole thread, it’s already mentioned

Kiitos suuresta työstä, maukka! :+1: :slight_smile:

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.
