This is my first attempt at modifying a mag-lite and it was on a budget. I thought i might share my efforts.
Basically its got 3 Cree XM-L emitters glued onto a solid metal reflector (as a partial heat sink), which are hooked up to a cheap DX 2.8A current driver. The switch has a blue led light drawing 5ma and is lit when the batteries are in the light (thinking about only lighting it when light is on, but this is much cooler). The host is a 4D black mag light with 3 18650's, however, i am yet to get a PVC spacer for the batteries. I also have a heavy copper heat sink which almost perfectly fits the host (salvaged from old CPU coolers i have laying around). The results are fairly outstanding, fairly good crisp throw and very bright! I will add beam shots when i have the battery spacer. Below are some pictures of the construction.
Would love some feedback
