Update: The M3 “HAMM3RHEAD” module is still going strong. I have two pair of Keepower 17500’s I’ve been cycling through. My next build will be to source a 17mm driver with the awesome guppydrv software similar to the Dr. Jones module I transplanted into my 6P, only one with a Zener mod I can use to crank out the 6 volts for the XHP50. The infinite programming combinations combined with the ability to lock it on single high or turbo output is a great option to have.
I’ve also contacted a local machine shop for boring options.
Put a new module together: Upped the ante with a 1.5A driver and trying a new XHP50.2 on two Keepower1200mah 17500’s I got from Illumn. The XHP50.2 doesn’t have the crosshair shadow in the beam. Incredibly bright inside.
My trusty Malkoff Hound Dog 18650 on the left, Surefire M3 with the new module on the right.
Secured a 17mm FET/DD driver running guppydrv rev2, zener-modded to handle the increased voltage. Ran it on an XHP50.2 from Kaidomain. Everything went great until I went to set the turbo-timer and the LED went bye-bye. An XHP50.2 with only one quadrant lit looks kinda funny. 🥴 Anyway, grabbed an XHP50 from the parts bin, this time one from Mountain Electronics on a red Noctigon. Since it wasn’t a .2 version, I flossed it, and wired it up. Still going strong. Was able to set the turbo-timer without it incinerating itself, so I got that going for me. Still testing! The guppydrv is great, love the flexibility.
- Going to get a few XHP50.2’s from Mountain Electronics and try those out.
Update: Since I bored out my M3 with a lot of sandpaper and patience, it will now fit 18mm cells. I made a simple 1-mode XML2 module for it with a 17mm 2A driver from Mountain Electronics. It will now run a single 18650 (with a spacer made of an aluminum rod and tape) just like almost everything else I have now.
