I ended up putting a FET driver in mine and SST-20 3500K but I am second guessing this decision since SS and tiny pill is not ideal for this. I turned the 219B in it originally blue instantly.
~400lm
In case it helps anyone here is the driver they are using as of this latest batch:
I tightened the retaining ring on the driver, unfortunately it made no difference.
I tightened the retaining ring on the switch assembly, which did make a difference, it seems to be working fine now!
I noticed that when completely disassembling mine to see how it worked. To fully tighten the tail retainer it ends up being just below the 2 cutouts for the lanyard and it’s not simple to fully tighten cause I think there is an O ring there for good measure.
I just modded mine: What did you mod today? - #9588 by MascaratumB
Put a 15mm FET driver with Bistro HD OTSM, a 10mm DTP MCPCB with a Luxeon V2 3000K and a pebbled TIR !

About the heat…I’ll need to have the unprotected Shockli cells to make it go hoooooot 
Do you have a link to the optic? I modded mine to use a CWF driver, but I’m not overly fond of the stock optic’s beam profile
I assume you mean Dragon Mini driver? Any details you can share like if the 7135’s fit as is? Sanding? Is there a 7135 on top side?
Yes I do! Here it is

Make sure you pick the right one as they have different options! This is a quite nice floody beam
Is this driver available separately? I have an SS incoming (2700K SST-20 since I like it) but think the low PWM frequency could bother me.
I ordered a new driver from Rey (he just released new drivers for his lights) for my non functional Enogear. Hopefully it will workout well
Hum, nice I will be looking for your feedback on it! Do you intend to use it with Ni-MH or Li-Ion?
I am asking because an older version whined too much with Li-Ion , besides the PWM it had :confounded:
This new driver seems to be different and that shortcut to turbo and other configuration options are quite nice
I switched both of mine to the DTP 12mm PCB’s from MTN:
It does fit with a bit of extra tightening (you really should apply a drop of glue when you get everything how you want so the head doesn’t come off “first” with the pill section being double threaded).
With FET + this DTP pcb + Vapcell H10 flat top it gets scorching hot in seconds. That cell is just absurd. I will keep the vapcell gold in there like I had before but at least now I feel better about the PCB.
Cool
That PCB is larger than the one I have and also larger than the original, but maybe it will dissipate heat a little better due to more contact with the pill
I also feel what you mentioned about the glue, but I didn’t do that, because in case I need to take it out again, I would struggle more :zipper_mouth_face:
Ahah, my Vapcell H10 is topped so it becomes bigger than I wanted, but I have some orange Shockli on the way, flat top, that will make the job :smiling_imp:
BTW, did you manage to use the retainingring with your driver? Was it thin enough to be put back in place?
Yes the ring is in place. It’s probably a half turn or so less threading but it’s there. I put one of those brass buttons on the bottom so only unprotected flat top 14500 fit now.
Nice! My driver was way too thick to put the ring back in place. Glad you made it with yours
Will you bet on the Vapcell Gold then, not the H10?
Yes, for this light and FET only driver. SS is just terrible for heat path. Gold takes 3-4x as long to get to same temp feeling. If you end up sagging that tail spring from leaving it on you are in for a world of regret 
Not sure if that would happen or not but seems possible?
BTW, does anyone know more about the FF copper AA light?

According to the specs it’s even smaller than the SS light!
CRX modded it a while ago:
Thanks! As I was afraid, the thermal path is terrible and there’s not much that can be done about it.
Not for me then. But I notice that there’s also a brass one with micro USB charging. 2 mm longer than steel, 1 mm smaller diameter. Worse looking.
Any more info about it?

ADDED: I see it’s out of stock…
Thanks again!
