BTW, I can't wait for the new heatsink. It's always a pleasure to collaborate with you. Make those fins deep, but not so deep that they can be leveraged.
Here's a cool little mod that I did for setting up a large capacity single Li-Ion Maglite...
This will be great for a single (or dual) FlexDrive set up!
There is plenty of room inside the head to mount the driver (or drivers), heatsinked to the back side of the main sink...
Pricing for basic 'Stubby' kit:
* Maglite 2 D host - $35 (or send me your Maglite - any D size Maglite can be cut down)
* Massive heatsink - $38
* Prep host (switch) with lead wires - $10
* Re-size the host as shown above - $20
It was a 3 D Maglite that I figured I would not use. So I turned it into this!
But in case anybody is wondering, the knurling on the D size Maglites, start at the exact same point under the switch. So it would look the exact same if you cut a 2 D, 3 D, etc...
Wait till you see my up coming XM-L T6 build I have coming. It will be a kit form, or a complete build. I'm going to design a custom mount/heatsink to hold the emitter with driver cavity.
I'll be testing 3 mode or 5 mode drivers for it...
It will retain the focusing ability of the Maglite!
