Finally got the Manafont "3T6" driver. The perpendicular circuit board is epoxied to the battery board. The epoxy covers several of the components. Fearing I would render the board useless, trying to separate it, I resigned to installing it in the pill (instead of in the space around the reflector. To build the depth of the pill, I cut a .25" length of 3/4" copper pipe coupler and pressed it into the pill. It was pressed to the shoulder that is the threads terminate at. Here is pic with the extension press in, the driver, and the driver in the pill.
Although this route gives more than adequate space for the wiring and driver (driver was not changed), I would not recommend this much of an extention. In order to fit my protected cells, I had to not use a battery spring on the driver and had to switch to a small P60-type spring on the tail cap. Even with that, I can barely tighten the tail cap enough to work. For the emitter side, I used a copper slug to bring up the emitter to the base of the reflector. I soldered the slug and copper sinkpad to the pill. Used a XM-L2 T6 3C. With the cells charged to 4.17V, current at the tail was 2.86A. This number sounds high to me because I thought this driver was a 4.5A driver. With this set up, this light out throws my Defiant Super Thrower (10 7135's, XML U2 NW, Parellel 18650's), my ZY-T08 (stock), HD2010 (11 7135's, XML U2 NW). It only out throws them due to the higher current. With the same current, the others would out throw this light. That being said, I would prefer this light to those in most situations because the throw is already more than I need and the profile is very nice. The great thing is that the transition from the "hot spot" to the spill is so smooth that you get a wider long-distance viewable area. To me, the hot spot is not discernible when looking out far. I live in a very thickly wooded area and I can peer deeper into the woods with this beam profile, because I don't get blinded as much by near by trees as I pan the light
