I've done a progression of stubby Mags refining my basic design and adding power. This is the latest and probably be the last one for a little while, as I have some other ideas to try. I couldn't consider the series complete without doing an SST-90. In keeping with my usual approach, the goal was to build a light that is respectably bright yet practical, so I didn't try to pull big amps just for the sake of being able to burn wet grass at 100 yards. The current at the tail cap, measured with a Fluke 117, is 5.2A on High, 1.46A on Medium and .22A on Low. Medium fires enough light out the front for most purposes and run time is quite long with an IMR 26650. It is very bright on High. I've run it tailstanding for fifteen minutes at a time and it gets very warm but still holdable.
The host is dark gray. It's just a tad darker than the pewter hosts that I've used in the past and provides a nice contrast to the bright trim.
This one is a bit longer than my earlier stubbies. The first reason is that it uses the Rebel reflector, which is quite a bit deeper than the standard Mag reflector. The second is that the heat sink is longer than usual, to provide lots of contact area with the body to promote heat transfer. The heatsink mates to a very smoothly machined surface inside the body with a very thin layer of thermal grease between the two.
The heat sink was bored to take a copper slug that is about .7" long.
The slug is tapped for a machine screw to insure that it stays put. Even without the screw, it won't likely go anywhere because it is a tight fit in the bore, requiring the force of a bench vise to push it home.
The top of the slug was machined to take the SST-90, which was reflow soldered into place.
This is a 5700k emitter.
The driver is a three board stack consisting of a ShiningBeam #1217 and two 4x7135 boards in parallel.
The bore at the rear of the heat sink is sized for the diameter of the battery.
The Mag switch is replaced by a McClicky in the tail cap. A small brass disk was soldered to the spring to improve contact with the base of the battery.
Two #4 flat head machine screws were tapped into the heat sink to hold it in place even though the fit is pretty close.
The LED needs to be recessed quite a bit because of the extra length of the Rebel reflector.
A Delrin sleeve holds the battery and an o-ring holds the sleeve in place so that it doesn't fall out while changing the battery.
The glass is UCL from flashlightlens.com.
Beam shots to follow after dark.
This light ought to make someone very happy. It's a lot of money for a Mag but it's a lot of Mag!
