I'm hoping it will be as easy mod upgrade to a driver running Anduril 2 with the tactical switch support. All that means for Anduril 2 is that a power switch ON turns the LED on to the last used level instead of leaving the LED off, as it does normally. I got a couple modded lights with an e-switch and a power switch running like this, and for me it works pretty well.
Just wish Wurkkos made this light this way, out of the box.
I was sort of hoping I could put my usb dongle to use and flash the existing driver. Please let me know if you find a suitable driver. It will be cold out before I have time to take it apart myself.
Mine arrived. I found a tube light that is actually longer, 138 mm vs 136.5 mm, than the FC12. It's an Eagle Eye X5 on the left:
Also found tailcaps that fit and work, but not the other way around:
This one may be my favorite:
Even an old SWM C20C cap fits:
I do like the beam. As others said because of the deep reflector, the hot spot is well defined, the flood area is small but bright. Also I noticed the lower levels don't have the green effect I see on my custom FET+1 drivers with the SFT-40. For the FET+1's, on the lower channel 7135, there's a noticeable green. Not sure why but must have something to so do with PWM'ing at low amps (0.35 amps). The stock driver on the FC12 doesn't have that effect.
It's funny because the reflector looks designed for a 3535 XP footprint LED. It looks like the reflector is actually sitting on the corners of the LED because the hole is too small, but it works well, appears to be well centered.
Overall now, I'm glad I ordered this light.
I did measure ~6.3 amps on a 30Q and ~7.3 amps on a 25S cell, so it does vary based on resistance of the cell. Not sure, but at least on max/turbo, it may be in full FET mode. Just a spot check on the 30Q had about 1800 lumens at start which probably makes sense from the amp readings. It's a small light so heats up quick at these levels.
Mine didn't come with a manual - hope I can get one to download.
