This is only my second install. I sure picked a tricky hilt to since this one as very little room. Its a very simple setup with a BLUE Luxeon, Pico Crumble Lightside (with recharge port), smaller 18500 3.7v battery and 20mm speaker.
Cramfu'd it all in there and it works well. At some point I'll update the LED to a Tri-Cree and work on FOC.
