So with experimenting, I managed to blow the driver from this E-series head, from too much voltage. I took the opportunity to tear it apart and toss a FET driver in. The biggest issue was removing the driver, as I didn't know if it was threaded in/ glued in/ press fit. I tried a few techniques, and ended up drilling a couple test holes in the edge of the reflector, to see if I could pull it all apart.
The bottom line is that there is a partition that the LED board sits on, with two small wires through down to the driver pill. Once I had the reflector out, it was pretty simple to lathe out the insides to fit a custom pill. I just made a simple aluminum pill, you can see it here, next to the original:
I did have to make a different battery spacer. The Fivemega host body comes with one more suited to a standard SF head. You can see it here:
I think it turned out well, the Nichia 219c is a good replacement size-wise, so the reflector is pretty much as good as before.
