FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public

A mechanical tail switch is on or off and uses “off time” or “on time” to determine the action you are making. An e-switch can have hold functions and utilize single/double/triple/etc.-click operations without the light turning off at all.

If you’ve used any of the Emisar or Fireflies lights, its allows for an updated version of that UI vs something like Bistro or Biscotti where its just taps to do a quick power cycle that also changes modes.

That sounds very useful. I’m mostly used to dual switch lights, so I didn’t realize single mechanical switch lights would have an issue with turning off when you switch modes.

Thank you.

Yeah, a mechanical switch physically disconnects power. It literally can’t keep putting out light while the switch is off, because it’s effectively unplugged. The user interacts with it by connecting and disconnecting power, which makes it a little difficult to do anything fancy.

An e-switch works more like clicking a mouse on a computer. It can be up or down, but in both cases the computer keeps running while you press the button.

Stuff like “hold the button to ramp” doesn’t work on a mechanical power-disconnect switch.

I’m in for 1

Please add me to the interest list. Thank you! This is my first post ever on here, I’ve been reading forever though. :innocent:

I am already on the list but can you add me for one more please

Hello! Put me down for one of each :D. Thank you.

I’ve been lurking for a while, finally joined because this looks pretty interesting. I’d like to be in for one (for now)…

Put me down for one, please.

XPL HI.

I’ve been reading up on this light lately (new to the forum); and yup, I think I “need” one. Please put me down for 1. :slight_smile: Thanks TK and crew.

Edited to add: most likely an XP-L HI, but possibly the Samsung depending on beam and tint bin.

Ok, I can’t take it anymore, please put me on the list for two with xpl hi. Thank you!

I’m interested in the Samsung emitter option. Please add me to the list. Maybe the XPL version too

Hi,

Please add me on the list for for one xpl-hi. Thanks!

Thanks - it wasn’t that far back, so I actually started with “A” and read everything after.

I really hope the final product will accept a wider range of battery lengths. Nothing to lose by doing that.

Its a balancing act between fitting shorter cells (how they were designed and sold by the original manufacturers) or longer button-top/protected cells. You always sacrifice some fit on one end of the spectrum for more on the other.

I would not group button top together with protected. A button top only adds 1mm while a protection circuit adds 4-5mm. That’s a big difference.

The FW3A should fit flat top and button top (most or all, I’m not sure), but not protected cells.

Just made an account for this, put me down for a LH351D!

Edit: Put me down for an XPL instead!

Please put me down for 1 LH351D! Thanks!

From my highly non-technical & less than scientific research :face_with_monocle: , my predictions for FW3A Battery Fitment are……

  • Most all 18650 Flat Tops will work.
  • Most 18650 Button Tops will not work. This will depend entirely on the height of the 'Button Top' installed on the cell... but it ain't looking good for "button tops".. . :wink:

These findings are based on the stated Maximum battery length of 66mm for the FW3A. :+1:

Since both pair of my calipers are hiding from me at the moment :person_facepalming: , the measurements listed below are taken mostly from LIION Wholesale & MTN… with a couple from Illumn & IMR.

…….
Flat Tops

  • Efest 18650 3000mAh Flat Top / 65.02mm
  • Efest 18650 3500mAh Flat Top / 65.25mm
  • Hohm Tech Life 18650 3077mAh 20.7A Flat Top / 65.12mm
  • LG HG2 Flat Top / 65.20mm
  • LG MJ1 Flat Top / 65.0mm
  • Panasonic/Sanyo NCR18650GA Flat Top / 65.30mm
  • Samsung 35E Flat Top / 65.3mm
  • Samsung 30Q Flat Top / 64.85mm
  • Sony/Murata VTC6 Flat Top / 65mm
  • Vapcell 18650 20A Flat Top 3000mAh / 65.0mm
    _
    Button Tops
  • Efest 18650 3000mAh 18650 Battery - Button Top / 67.1mm
  • LG HG2 - Button Top / 67.0mm
  • LG MJ1 Button Top / 66.8mm
  • Panasonic/Sanyo NCR18650GA Button Top / 66.8mm
  • Samsung 30Q Button Top / 67.3mm
  • Samsung –35E Button Top / 66.9mm

So, in summary; there are plenty of flat top batteries that will fit the FW3A even ’if’ no button tops fit at all. :beer:

Now I don't feel so bad about buying flat top 18650 cells!

I wanted button tops, but couldn't find any for the cells I wanted.
