I put pebbled TIR , replacing the SMO reflector and AR Coated glass lens. I kept the black gasket around the LED, and I put a black o-ring a between the TIR and the bezel (it has a blue one originally, but it was causing some blueish shift in the beam with the TIR).
Here is how the beam looks with the TIR. It has, obviously, less throw, less intensity, it is floodier, but has no artifacts on the beam!
