I just purchased a brand new KX2 a few hours ago. In comparing it to my KL1, switching the heads back and forth (trying each head with both primaries and a 17670), my KX2 screwed apart instead of off the body. Looks like Surefire didn't use much threadlock at all on this one, so I took advantage... and took some pictures! I searched but didn't come across any other threads with pictures of a disassembled KX2 or KX1, so here you go...
FIrst, the two halves of the KX2 as they came apart in my hands. As you can kind of see, the KX2 is similar to the KL1 in that it uses top and bottom pieces ("upper bezel" and "lower bezel") threaded onto a double-sided male connector that holds the emitter ("heatsink"). I was unable to separate the heatsink and lower bezel, though I really didn't try very hard.
Same view, looking down. You can see that the emitter board is attached to the heatsink via two hex screws. I could not find the right size hex key, so I did not remove them. I may do that some other time, but I'm more interested in the optics of the KX2 than the electronics. You can see the TIR optic and its retaining ring here, which screws into the same threads that the heatsink does.
A (somewhat dark) view into the upper bezel and TIR optic. Not much else to say, this isn't a very good picture...
Left to right: Lower bezel with heatsink/emitter; TIR optic retaining ring; plastic washer; TIR optic; pyrex lens; rubber washer (or o-ring); upper bezel.
Same, from slightly more above.
Close-up of the aluminum ring that retains the TIR optic in the upper bezel.
The next two are the TIR optic, facing down. It appears to be comprised of two separate pieces, a completely flast disc on the bottom topped with a cone-shaped optic. I could be wrong, and it's a single molded optic, but it looked like there was a seam connecting the disc and cone.
TIR optic, facing upwards. At the top of this picture, the optic has a completely flat surface all the way across, not domed like the KL1's TIR optic.
While looking down into the assembled KX2, one might think that there is a reflector inside. I see it, too. However, there is no reflector in the KX2 separate from the TIR (total internal REFLECTION) optic. And as you can see here, the rubber washer/o-ring is visible through the optic, so it is itself fully transparent even sideways.
On the other hand... this optic sure does reflect well! You can see in the center of the optic, the reflection of my ceiling fan light. On the left of the optic, you can kind of make out the reflection of my American flag. On the right of the optic, is my window with blinds, and just left of the window, my monitor with CPF on it.
And finally, in the fine tradition of Maglite, I give you... candle mode! :candle:
It really is quite bright, lights up my dark hallway very well. I just wonder about the lessened heatsinking due to the removed upper bezel; on the other hand, the emitter is exposed to open air.
So, there's the inside of the new KX2. Hope you enjoyed it! :wave:
