Inspired by Olight SR95 UT, I built a FM3X UT using P-bin CBT-90 (Even better than SBT-90 used in SR-95 UT, because that the CBT-90 is basically SBT-90 that came on on copper star).
I really love the FM3X UT, so I am going to try to make it happen on Mag 1D platform, targeting high lux with 3 modes. The closest light to this was a DIY Cut Mag 1D SST-90 I made while back,
In this build, I am for various improvements: Smaller host, seamless cut, longer throw and 3 mode to make it more useful…
Part I. Making of the host
Cutting the 3D Digital Camo mag tube
Bore the tube with a 35mm hole saw to 35mm
Bore out the 1D tail section to very thin
Cut the thread section of Mag body & grind the wall down to very thin
Insert the thread piece into the Mag shorty tail, apply JB weld at the internal groove junction.
Thread in the tail cap part way & push the thread all the way in,
then polish the end, until it looks like this:
The tail will look identical to OEM
Including the original OEM anodized threads

Now, moving on to modding Bright Lumens SST-90 heat sink.
Drill down the center post
Grind down the rim of post as well
Grind down the rim. I’ll be using using the heat sink backwards
Drill a dimple in the center of the rear to get rid of the center residue that’s raised slightly
Moving on modding the CBT-90
This is a beautiful Led, the cover glass over the die is actually AR coated. Beefy copper heat sink is just a bit too big for mag, need some operation.
Cutting it with a cutting wheel took solid 2 hrs, because it need to be cooled down constantly.
Fits perfect in the rear of the heatsink, the well meant for driver circuit
For soldering the led, I chose 20AWG teflon wire. I also have 18AWG but that’s way too hard to work with, look how much thicker it compare to the 20G (Orange & Brown).
Did a quick test making sure the led is still working
Spread the arctic Silver, make sure to center the die perfectly & press down with the Mag Rebel SMO reflector (Quick focus stem was cut-off)
