good to know
I agree the Aux board would do well to be removed
the main problem w the SP10 reflector is that it is short and wide, with a large base opening, so it produces a wide unfocused hotspot
PNWest already proved that the stock 5050 LED wont make a focused hotspot in a reflector (they used the stock bezel and a cut down reylight reflector), but it might work to create more throw if someone was to also replace the KR1AA 5050 mcpcb with a 3535 mcpcb and install the 6V Nichia 719a.. This would allow keeping the stock driver.
So far nobody has used a KR1AA host to build a thrower. One solution involves a new 3V driver, compatible with small 3V 3535 LEDs, in addition to a reflector and possibly a longer bezel.. that would make it essentially an entirely different light than the existing KR1AA.
Bean_Master7 has mentioned wanting to use a thefreeman FWAA Driver, which requires assembly.. it is not available in completed form. He has talked about using an SFT25, similar to the Wurkkos TS10SG.
I would have little interest in a Low CRI LED.. the one thing that is unique about the TS10SG is that it uses a Tir, not a reflector. But I dont know if that Tir fits a KR1AA..
I had also hoped the KR1AA would be more throwy than the D3AA.. but I have come to accept that is not possible with a 5050 LED.
I say that based on my experience with Zebralight H600D and Skilhunt H300R, both with XHP50 LEDs and reflectors. Those lights have big wide floody beams.. no focused hotspot at all (except at very close range).. the limitation comes from the width of the 5050 LED. A reflector does not change that.
