Minimag Cree XR-E mod (mostly) completed!
I finally managed fit a Cree XR-E into a Minimag body. A BB400 was modified to a BB670 using a coil of resistive wire (no BB750s in stock at the time). This was stuck on with garden variety superglue to the non comductive side of a one-sided copper PCB which acts as a ground plate.
A Cree P4 bin was soldered to the Cree PCB and a 50-50 mix of silicone thermal paste and epoxy used to adhere the PCB to to the mag body.
The stock reflector was replaced with a temporary mounting of two cheap plastic lenses to get the required focal length.
Still waiting on a Terralux clickie and some decent optics like the 22mm aspheric Amonra plans to sell to get a better throw.
Body
Head
Cree mounted on PCB.
Optics (notice the dodgy trimming on the lenses)
Flood beam at 4m
Spot beam at 4m
Building about 20m away
Building about 80-100m away (The lit tree is a lot closer)
