ooh. I like that U.I. Simple and practical.
I'm kind of puzzled by this as well. Surefire IMHO usually has the best simple straightforward UIs(despite how many levels, functions etc the light has) and don't use the cycle the levels by clicking on/off method(which I'm no fan off). Have they done this before? Maybe it's a move to a more civilian market less gun oriented market? I could see how this light could be a great lights for EMTs etc with the existing UI. Although they should maybe change the clicky to a reverse.Simple? Yes.
Practical? Far from it.
There's a reason why multi-output lights from other companies use a reverse-clickie, and why Surefire's U2 with its forward-clickie relies on a selector ring.
If you use the momentary function on such a light, hope your thumb can maintain constant, direct, pressure. Cause if it can't, the light will go out. You'll instinctively apply pressure the moment the light goes out, and look at that... now you're getting either too much or too little light for the task you need to complete.
Ironically, after getting it right with the U.I. on their U2, Surefire has taken a big step backwards.
I've had one for about 6 months. I also have the 3 cell version. Surefire 115 lumen rating is close by eye to my Fenix TK11 on turbo. The KX3 head on the prototype was a tiny bit beefier. UI is simple 3 light level a 1 second pause before clicking in desired level. Great light for EMT's and Rescue.
Drop-in? It's a sealed head just like the KL4, KX2, KL1, kx1, KL5A... You either buy a complete head or you buy a drop-in for a SureFire bezel ( incandescent reflector only, no TIR or LED module).Will this light be compatible with any malkoff dropins, I noticed from the pictures that it utilizes a kX3 head.
In fact are they selling this head separate?
