Okay, so I guess I got the light out and started fiddling with it.
Driver gotta go. Blech.
Wow, tight beam, and pretty bright!
So I took a Nanjg105c, removed 4 of the 7135s and jerry-rigged it to fit the driver hole:

It doesn’t look all that great, but it fits super snug, it’s not gonna pop out!
With a little bit of custom Luxdrv, and some heatsink goop around the LED, it’s good to go!
BTW, I removed the little spacer/spring cap that goes between the driver and the battery, and I also left the tiny spring the Nanjg comes with, rather than the inch long junk it had, and now any battery I wish fits properly and things close all the way. (They definitely didn’t before)
After mods= GOOD light.
Now I might not give it away…. hmmm.
