I got this light as an EDC option that is thinner than my Convoy S2+. I haven’t seen information on modding this newer version of the light so I thought I would post my experience with it. As far as I can tell the front portion of this light is similar to the last XP-G2 version, but the tailcap portion and belt clip are different. See here for a review of this light.
Unfortunately both the bezel and tailcap threads are glued. Fortunately I was able to un-stick them with a bit of heat (~50C just by holding a lighter under it) and rubber inner tubes and pliers. At the tailcap, the body presses down directly on the switch PCB, with no separate retaining ring. At the front end, the shelf is integrated into the head. The stock MCPCB is 10mm, and I don’t know whether it is DTP or not. It is about 1.0mm thick.
Now for the mod. I am happy with the beam size of my S2+ with XPL HI and narrow TIR, so I aimed for a similar beam size with this light. I chose a dedomed XPG2 S4 2B. For the driver I used a 15mm FET-only driver from mtnelectronics. Ideally I wanted AA compatibility, but I guess I wanted maximum output even more. I used the windyfire 14500 cell from mtnelectronics which is about the best high-drain 14500 cell around.
Here is a picture of all the parts, plus the TIR I ended up using.
Tailcap parts. I added the spring bypass.

I wanted to see if I could find a TIR because I tend to prefer the beam a TIR offers. I ordered some TIRs from kaidomain and ended up using this one: kaidomain.com/p/S021430.15mm-x-9mm-LED-Glass-Lens-(1-Piece)-Clearance. I used a 10mm tpad MCPCB from mtnelectronics. I used an convoy L2 centering ring, available from mtnelectronics, to center and space the TIR. I had to do some creative trimming on the centering ring because there is really not a lot of room between the solder pads on the MCPCB.
With the dedomed XPG2 in stock reflector, I measured 11.7Kcd. With the TIR I measured 13.5Kcd and about 850 lumens. It pulls about 3.5A on the fresh windyfire cell, measured with a 10 mOhm shunt resistor bypass at the tail. Below is a comparison of the beams with stock reflector and TIR, both with dedomed XPG2. It is a good representation of how the TIR gives a bigger hotspot. The lux at the beam centers are similar, but the TIR beam is significantly bigger. The TIR beam is just a bit bigger than the beam of my S2+ with TIR, so I’m pretty happy with the result. I just flashed Toykeeper’s new clicky ramping FW, Crescendo.
Finally a picture of the complete light and my S2+.
