Atomsphere: I think that's actually a McR-27 reflector in a Aleph1 head, which has replaced the NX-05 optics. The head's too big to be just a 17mm reflector, and it's not deep enough to be a 38mm reflector. It COULD be a 20mm, but I'm estimating 27mm based on the angle and the look. But that could also be a PR head....
That'll DEFINITELY improve the throw, however, and maybe increase the lux of the beam at the center hotspot.
