Here's some pics:
Modified Sipik SK58 with XM-L and reflector taken from old underwater kinetics 2xAAA incandescent. Lens is off:
Here's a pic down the business end of the light in full flood mode with the reflector and lens on:
Here's a beamshot in full flood mode. The reflector eliminates all rings in this mode while adding a wide diffuse spot in the center of the beam. Unlike other zoomies there also are no rings outside of the spill in this mode. I love how flood mode looks. Much floodier than the beam from a Xeno E03. And much brighter too with the driver I'm using:
Halfway mode. This looks a lot uglier, but on the other hand the reflector is providing usable spill. Without the reflector everything outside of the bright spot in the center is gone:
Full spot mode. Note the halo and artifacts from the reflector. The beam is pretty ugly, but in real-world use this halo is bright enough to serve as usable spill, without affecting the light's throw. Note that the slight black half circle just above the image of the die was where a bit of the silver reflective coating accidentally chipped off when I was drilling the hole for the emitter.
Note that all modifications on this light were performed using my own rather amateurish do-it-yourself methods. Nothing professional quality about this mod.
