The SupFire X5 is a nice looking light that Summer from DinoDirect offered a discount deal to BLF members. Here's a pic of the light from her posting:
Here is a picture, also from her posting, showing the X5 stock pill on the right:
Here's some photos of the pill mod I did for the X5. Sorry, didn't have my own "before" pics of the pill. The original had a 1 sided 17 mm driver with a brass retaining ring, holding the driver in place, all aluminum, no brass.
Brass ring (FastTech) pressed in, shows copper disc inserts. I grinded down the inner thread part of the pill where the brass ring screwed in, and had to grind the inner walls to get the opening wider for the brass ring:

Shows how the 20mm SinkPAD fits. Plan is to use grease, not epoxy, and sand the SinkPAD and pill top til silky smooth (2500 grit):
The original star sitting on top of the SinkPAD for size comparison below. The SinkPAD appears slightly bigger, specially with the flare-outs, and I've found that the SinkPAD's needed to be filed or sanded down to fit where a standard 20 mm fit fine. In the X5, no problem, because the star mount area is a bit oversized.
The bare brass ring used on the left, alternate pill I was thinking of using on the right - this brass pill would be ground down, removing a lot of the threaded portion (lip around the emitter mount), and the outer surface to reduce it's outer diameter, then press fit it in, but also requiring grinding on the inside of the alumimum pill - a lot of grinding but the dremel works great for this stuff. Nice thing about the using the pill is it's more mass than the ring, so maybe more heat sinking, but the ring was less work.
Now you got a pill all set for mounting a standard 17 double sided driver with extras heat sinking in the critical area, just below the emitter. I'm calculating the effective height is the same as the original with the retaining ring, and plan on re-using the original spring on a Nanjg driver setup for 3.85A. The mass of the SupFire X5 a little more than a typical C8, so figuring a U3 1C mounted on the SinkPAD will do well at 3.85A in this setup (it will get hot after a few minutes none the less).
The brass rings are from FastTech here. FastTech also has these pills, though I purchased mine from FancyFlashlights. That's it for now. I'll post updates, or at least final assembly and test results.
Update 02/10:
Star and pill top surfaces prep'ed, sanding up to 2500 grit:
Reflowed U3 1C, set to Arctic Alumina grease:
Nanjg driver with 3 7135's added:
Pill assembled, spring transferred (driver is a 2-5 mode job from FastTech so no mode soldering):
All put together, showing the emitter:
